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:I would like to use a two-point output pressure switch to achieve high pressure stop pump, low pressure pump, I would like to ask how the line should be connected, the best wiring diagram, thank you.
so that even if the pressure will not stop the high point of the pump;
Q:What is the oil pressure switch?
Monitor the oil pressure, oil pressure is low, then the instrument panel has a red oil tank alarm light will be bright. All engines must be equipped.
Q:Hello! Will the air compressor pressure switch how to tune ah? There are two plugs in the switch screw, one is the plastic screw, one is the iron screw?
Two screws are located in the left and right columns, each column has a different scale display, the screw is used to adjust the pressure, the right side of the adjustment is the pressure difference, the left side of the pressure limit is adjusted, such as the right side to 2, Adjusted to 8, then the controller to control the compressor to start the way, six kilograms of pressure to start, eight kilograms of pressure to stop. Do not know if you understand, do not understand can consult Beijing in the Year of a Trade Co., Ltd., professional air compressor repair and post-processing equipment maintenance professional service providers
Q:Fire water flow instructions, pressure switch, signal butterfly valve their role
In accordance with Specification 6.3.1 In addition to the alarm valve group control of the nozzle only to protect the area of fire outside the same area, each fire partition, each floor should be set up water flow indicator. 6.3.2 Under the roof of the warehouse under the nozzle and the nozzle should be set separately water flow indicator. 6.3.3 When the control valve is set before the inlet of the flow indicator, the signal valve shall be used. 6.4.1 rain shower system and fire separation water curtain, the water flow alarm device should adopt the pressure switch. 6.4.2 Pressure switch should be used to control the regulator pump and should be able to adjust the start and stop pressure.
Q:How to determine the car air conditioning pressure switch is good, or bad? What are the steps and methods of operation?
Air conditioning pressure switch is usually two, one is low-voltage protection, one is high-pressure protection, the approximate principle is: When the pressure inside the system is increased when the pressure is set, the pressure switch is automatically opened, the system stops working. When the system pressure drops to the set pressure, the pressure switch is automatically connected. The system is working normally. The air conditioning pressure switch is the air conditioner Pressure, and then the pressure signal to the air conditioning control system, play a protective air conditioning compressor and the role of the pipeline. Only the pressure signal in the normal range, air conditioning can work properly.
Q:Where is the pressure switch?
my machine is to use this pressure Table, the feeling can be right, no defense, you can try trial
Q:Hot and cold water automatic self-priming pump how to adjust the automatic pressure switch
The normal pressure switch is a small can similar to the gray, the small jar cover open, the middle of a one-inch screw, you can quickly screw the screwdriver can be, a less tune, about 1/4 turn, you can The So that you can mobilize the pressure.
Q:Home booster pump water control automatic switch how maintenance
Flow switch failure. May be stuck by the garbage in the water. Remove the rinse. Or replace the water flow switch.
Q:What is the difference between a pressure switch and a differential pressure switch?
The main difference between the pressure switch and the differential pressure switch: 1, the structure is not the same: (1) pressure switch with high stability, high precision pressure sensor and transmission circuit, and then through a dedicated CPU modular signal processing technology to achieve the media pressure signal detection, display, alarm and control signal output. (2) and the differential pressure switch is composed of two high sensitivity of the pressure element, if both change, it will cause the switch mechanism to control the equipment such as motor-driven valves. The switch mechanism provides the SPDT non-fast acting (floating) action, so the shared movable contact will touch one of the two fixed contacts, or stay between the two (no contact).
Q:Computer-type electric pressure cooker normal heating, any function time after the show E4, functional time should be after the pressure, please master guiding.
Pressure switch failure, pressure switch and insulation switch similar. The pressure switch is used to detect the working pressure of the electric pressure cooker. When the pressure inside the pressure cooker close to 80KPA when the pressure switch action, and then cut off the power supply to the heating plate, so that the pressure inside the pot to maintain the standard pressure. The position of the pressure switch is mounted on the edge of the pan bottom heating plate, with a contact facing the heating plate. Put that stuff on it
