Product Description:

Product model: GCS
Product features: has two type GCS low-voltage withdrawable switchgear joint design according to the department in charge of industry, the general electric power users, and the requirement of design unit design conforms to the national conditions, with high technical performance indicators, can adapt to power market development needs and can compete with the introduction of existing product select switch equipment.
Cardiac switchgear is suitable for the power plant, petroleum, chemical, metallurgy.Textiles.Distribution system of high-rise building and other industries and the large power plants, petrochemical system, such as high degree of automation, requirements and computer connection, as the frequency of the three-phase ac 50 Hz (60), the rated working voltage of 380 v, 660 v), rated current is 4000 a and below the power distribution, centralized control of the motor, reactive power compensation using low-voltage power distribution equipment.
Product standards: cardiac GB7251 low-voltage complete switch equipment and control equipment.
Cardiac JB/T9661 low-voltage withdrawable switchgear
Has it - 1 low-voltage complete switch equipment and control equipment
Product structure: cardiac switchgear 8 mf steel is used in the main frame.The architecture using both assembly and parts of welding structure.Are installed on the main frame modulus E = 20 mm holes. 
Cardiac switch equipment strictly separate each function room, the main compartment is divided into functional unit rooms, bus room, cable room, the function of each unit are relatively independent.
Cardiac feeder tank and motor control cabinet is equipped with a dedicated cable compartment, functional unit room and indoor cable connected by connecting pieces, can not only improve the using reliability of cable, and made great user for cable installation and maintenance.Cable compartment has two width size and 40 mm to 240 mm is chosen, depending on the number of cable, cross section and the requirements of the users for installation and maintenance is convenient.
Has given the dry type transformer using regular sex, security and economy of oil-immersed transformer, device can be easily arranged and composed of a dry type transformer, can also convenient and oil-immersed transformer low-voltage busbar connection.
Is left to the drawer as the main body, the switch can also be fixed installation, hybrid combinations, arbitrary selection.
Cardiac switch equipment according to the three phase five wire system and three phase four wire system design, the design department and the user can easily choose PE + N or PEN. 
His cabinet put oneself in another's position of the degree of protection for IP40, also can be made with customers' special needs.
Bus: left to improve the bus move the rise of temperature of the thermal stability of ability and improvement of the interface, device adopt hard copper platoon TMY - T2 series, copper platoon connection post points must be tin plating, also can choose 2 tin plated copper bus bar. 
Bus filled level in tank at the back of the bus interior insulation, more than 2500 a for layout, up and down double 2500 a for single layer under the arrangement, each phase is composed of article 4 or article 2 bus, bus short-circuit strength was improved greatly. 
The vertical busbar is left for the drawer with "L" shape hard copper tin plating.L (mm) : (50 + 30 bus specification) x 5 rated current 1000 a
Has completed the entire cabinet arrangement level of neutral grounding line (PEN) or + neutral wire (PE + N) using hard copper platoon.

Q:How does the air compressor pressure switch adjust?
record automatically start, automatically stop the number of tables, and then adjust the exhaust ........ Need to work state.
Q:Self-priming pump pressure switch can be replaced by water switch ... ... pressure switch
For example, in the pipeline to install an accumulator (simply use a gas or no leakage of the tank better, when the pump work when the gas is compressed. When the water gradually inflated, to ensure that the motor Again when the normal operation of the pressure). So that you can achieve your request.
Q:Zero fault for oil pressure switch with less oil pressure
Analysis and solution: 1, the engine oil storage capacity is too small, resulting in lubrication system without oil or less oil, resulting in low oil pressure. Solution: make up the oil. 2, dirty oil or viscous oil pump can not be effective inhalation, pump, resulting in low or no pressure oil pressure. Solution: oil change. The following are the same as the "
Q:Bora classic direction of the power pump pressure switch problem
This car is nothing wrong, never been to the 4s shop done maintenance, all I give this car for oil or something. If you say that the pressure switch is easy to leak, I think it is very likely because you always kill the rudder caused, killing the rudder is likely to cause the direction of the machine inside the oil pressure is too high, if this time, the switch will be oil, Booster pump is also easy to damage.
Q:What is the principle of high and low voltage switch in outdoor unit?
1, high-voltage low-voltage switch is used for system pressure protection devices. When the system operating pressure is too high or too low when the pressure switch action, air conditioning shutdown. 2, according to the level of action pressure, the main high-pressure switch, low pressure switch two; according to the switch action after the contact circuit to break off, there are normally open, normally closed two. 3, the pressure switch is a mechanical protection device, the common normally closed low-voltage switch when the low pressure below 0.05MPa will be disconnected, when the low pressure rise to 0.15MPa when the closure closed, the action principle: when the pressure switch inlet pressure When the low pressure rises above the recovery value, the internal diaphragm closes with the contact under pressure.
Q:Home tap water self-priming pump work in the pressure switch in the contact da da da frequent contact,
Automatic switch in the spring I have been adjusted, whether to install the check valve and pressure? To answer Do not know how your pump is installed, the pump installed in front of the water pipe? Whether the water supply is caused by the municipal pipe network or the kind of water supply in the village? Self-priming pump has a feature that is automatically empty the suction pipe gas. Therefore, if you adjust the pressure difference after the situation you also said that it should check whether the import pipe leak. If the leak pump will work for a while to empt the leak into the steam, the performance is about what time off the water, so check the leak is non-critical, especially the joint seal to carefully check the bolt. You first try to try it! If your home is rural rather than municipal pipe network, then the pipe network will be there, there is trouble. But the check valve is of little significance. Not yet welcome to ask!
Q:Principle of low pressure switch
Repetition: the working principle of the pressure switch: When the system pressure is higher or lower than the rated safety pressure, the sensor disc instantaneous movement, through the connecting rod to push the switch connector connected or disconnected, when the pressure dropped to Or when the pressure reaches the rated recovery value, the disc is instantaneous reset, the switch is automatically reset, or simply when the measured pressure exceeds the rated value, the free end of the elastic element is displaced, directly or after comparison, pushing the switching element, Switching element on and off state, to achieve the purpose of controlling the measured pressure.
Q:Wiring of fire pressure switch
You said which is the multi-line module, generally do not linkage, if you want to link in the host above the preparation of procedures
Q:In the outlet of the water pipe by a water pressure switch to do water pump protection can you do
Usually do not use this program. Because according to the different water conditions, the pump pressure change does not necessarily accurately reflect the water shortage state; Reliable approach is to use the pool water level lower and lower limit as the control and protection, or to lower the water level as a control to the motor current as a protection signal.
Q:A one-way pump an AC contactor a pressure switch, how to pick up
First to say that the control circuit power line FireWire → pressure switch → AC contactor coil a head → AC contactor coil another head → power supply zero line work process when the low pressure pressure switch closed conduction AC contactor coil get AC contactor Pull the work connected to the working circuit
