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:What is the principle of automotive air conditioning pressure switch
Hello! Pressure switch is to detect the pressure of air conditioning pipelines, and then the pressure signal sent to the air conditioning control system, play a role in protecting air conditioning compressors and piping! Only the pressure signal in the normal range, air conditioning can work properly!
Q:Pressure switch wiring
Your machine pressure switch is what model, say it to help you analyze the wiring.
Q:Specification or type of pressure switch for water pump
Export plus check valve on it, even if there is pressure, it will not return to water! Will not affect the pump seal. Pressure gauge pressure is usually set a pressure, it can be slightly larger, it will not start frequently.
Q:Pressure switch and pressure sensor the difference? same?
Hello, the pressure switch is a combination of a controller, a pressure sensor and a pressure transmitter that can output the displayed value.
Q:What is the output signal of the explosion-proof pressure switch? What standard?
When the pressure increases, the role of different sensing pressure components (diaphragm, bellows, piston) produce deformation, will move up, through the railing spring and other mechanical structure, and finally start the top of the micro-switch, the electrical signal output Explosion-proof pressure switch pressure adjustable range: 68.9 mbar to 861.9 bar; Explosion protection and protection class: to meet the 1 area and 2 area explosion-proof requirements, protection class IP66 Is the switch signal output Switch output: Code S: an SPDT, fully sealed switch.                   Code D: Two SPDTs as DPDT, fully sealed switch Such as this 12 series of all 316 stainless steel explosion-proof pressure switch 12SHSN2A 12SHDN7B 12SHSN4F 12SHSN3D 12SHDN5D 12SHSN5F 12SLSN7B
Q:Air compressor pressure switch
The working principle of the pressure switch is when the pressure inside the system is higher or lower than the rated safety pressure, the sensor disc moving instantly, through the connecting rod to push the switch connector connected or disconnected, when the pressure dropped to or When the rated pressure is exceeded, 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, changing the switching element On-off state, to achieve the purpose of controlling the measured pressure. The pressure switch uses elastic elements such as single-ring spring tube, diaphragm, diaphragm and bellows. Put the gas, because the internal solenoid valve opening and closing, internal and external pressure pressure, it issued a sound.
Q:What is the role of automotive air conditioning pressure switch
Pressure switch is to protect the compressor: When the air conditioning refrigerant in the air conditioning pipeline system pressure is too high or too low when the air conditioning pressure switch will turn off the compressor control power, so that the compressor does not work. When the pressure returns to the normal range, the pressure switch will open.
Q:Automotive air conditioning pressure switch three lines how to measure good or bad
Marked as NO for the static end of the static normally open contact, and C line between the open state. Three lines of a two resistance reaction, the performance of the resistance tends to 0 value.
Q:How does air conditioning pressure switch know bad?
If the compressor does not work, or the electronic fan does not work, the electronic fan is often the pressure switch is a problem.
Q:The role of automobile air conditioning pressure switch
Automotive air conditioning pressure switch is basically divided into: high voltage protection switch and low voltage protection switch two. Its main function is to control the operation of the electromagnetic clutch in the pipeline when the pressure of the refrigerant is higher than the pressure of the system or below the basic operating pressure of the system so as to achieve the purpose of protecting the air conditioning system.
