A, product overview and scope of application
KYN28-12 armoured medium type metal enclosed switchgear (hereinafter referred to as the switchgear) is my company in the absorption of advanced manufacturing technology at home and abroad on the basis of the design and development of new products, can replace the old type of metal enclosed switchgear, such as KYN1-10, JYN2-10, the GBC - 10 etc series products.Its product has the following obvious advantages:
1.1 products shell entirely by coated aluminium zinc steel plate after CNC machine tool processing multiple bolts assembled after bending forming, has high mechanical strength, effectively ensure the product's tidy and beautiful, cupboard door adopt plastic spraying coating, with strong impact resistance and corrosion resistance ability.Product is shell IP4X level protection grade. 
1.2 this product is the main switch can be configured ABB VD4 vacuum circuit breaker, C3 series fixed load switch, at the same time also can configure a variety of domestic series vacuum circuit breaker (e.g., VS1, VH1, vitamin k, ZN28), to replace the similar foreign products. 
1.3 whether to choose what kind of circuit breaker, the bare conductor insulation distance air can ensure that more than 125 mm, the composite insulation is greater than 60 mm.The circuit breaker has long life, high parameters, less maintenance, small volume of the unique advantages. 
KYN28-12 armor type of metal-enclosed switchgear is suitable for 3.6 ~ 12 kv three-phase ac 50 hz power grid, as acceptance and distribution of electricity, and the circuit for control, monitoring and protection purposes.Can be used for single busbar, single or double busbar system bus section system.Switchgear meet IEC298 52 kv and below the rated voltage 1 kv ac metal-enclosed switchgear and control equipment ", IEC694 terms of high voltage switch control equipment, our country GB3906 "3-36 kv ac metal-enclosed switchgear and DL404 indoor ac high voltage switch cabinet order conditions, German DIN. VDE0670" rated voltage 1 kv ac switch equipment, such as the standard requirements.And have perfect functions and reliable prevent wrong operation.

Q:How to control the pressure switch with PLC (ZSE30-ISE30A)? How is programming too?
For vacuum suction cups to detect whether the adsorption is good, the air pressure is negative. It depends on your pressure gauge performance. As far as I know, SMC commonly used two applications: One is 0-100kpa, which is displayed as positive, for blowing and other measures of the size of the pressure of the occasion; The other is -100- +100 kPa, that is, positive and negative all can detect the model. The signal you need can be obtained from it.
Q:What are the two lines of water pressure switch?
Four-wire pressure switch works are the same, about two high and low pressure switch, the upper and lower pressure switch; for example, the pressure at higher than 3.4 or below 0.196 disconnect the compressor Pressure higher than 1.7 when the pressure switch action, so that the condenser cooling fan high-speed operation. There are two lines are high and low voltage switch line, and then the root is the medium voltage switch line, above two are FireWire, High and low switches can be used directly with the line, the same pressure switch .....
Q:Principle of low pressure switch
US UE pressure switch for pure mechanical deformation caused by micro-switch action. When the pressure increases, the role of different sensing pressure components (diaphragm, bellows, piston) deformation, will move up, through the railing spring and other mechanical structure, and ultimately start the top of the micro-switch, the electrical signal output. UE pressure switch set from the functional principle is divided into continuous displacement and force balance type.
Q:Is the pressure switch of the motor controlled by the contactor requiring a separate power supply?
The control circuit is preferably low-voltage, so safe. However, the home, 220V do not know you mean the motor circuit, or contactor circuit. If the control side of the circuit, 220V is also not a bad idea, but as far as I know, there is no controller operating voltage is so high. The The You must not control it automatically. Then the contactor into a knife switch and the like can be used on the main circuit. If you are referring to the motor circuit, the control side of the circuit is best for low voltage. Ha ha
Q:Can you draw a concrete map? Thank you. The The I do not understand that. The - is it 24V ... The The please. The The
If the pressure switch is a switch of the more simple, direct access control box can be the collection side. Shandong coal electrical, professional control box and sensor production.
Q:Before we do fire linkage is only linkage signal valve, but suddenly see some of the drawings are also linked to the pressure switch, ask, what is the pressure switch with the shower signal valve is what ah! Do you need to activate the pressure switch after the linkage signal valve?
The linkage signal valve also need to linkage after the pressure switch, because the linkage valve to start the sprinkler system after the spray system will drop the pressure, the pressure switch will start the pressure pump to the sprinkler system
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:Control the pressure switch of the cold and dry machine fan is measured what pressure
Condensing pressure, to a certain pressure will jump, down to a certain pressure will jump
Q:How does the air compressor pressure switch pressure adjust? Read half a day to explain how the clockwise rotation at the same time increase the opening pressure and closing pressure, there is a clockwise rotation to increase the opening pressure and closing pressure unchanged
Closed pressure is to reach this pressure, the air compressor began to work, it should be the lowest value.
Q:After the power, display E1, to determine the sensor circuit problems, dismantling and found that one foot of the relay was blown off, replace the bad relay, and then power, show E4, to determine the pressure switch failure, I as a maintenance beginner, Once encountered such a failure, how to determine the pressure switch is good or bad, how maintenance?
With a multimeter resistance file pressure is set to 0, the sensor resistance is about 100 kilohms. If this measurement is this value, then the circuit board has a problem, check whether the circuit was blown, plug the card is bad.
