Product Description:

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:Home booster pump pressure switch failure how maintenance
Flow switch failure. May be stuck by the garbage in the water. Remove the rinse. Or replace the water flow switch.
Q:Bay fire equipment in the wet alarm valve on the signal butterfly valve and pressure switch
It may be 24v bar, pressure switch action in addition to the alarm after the host signal, but also have to start the spray pump. Your relay should play the role of conversion it. Pressure switch action after the start of the relay, a group of normally open point to the input module, another group of open pump
Q:Why is the air conditioning pressure switch called pressure relay
Temperature control switch is mainly to monitor the temperature of the condenser, the temperature is too high to cut off the electromagnetic clutch circuit to prevent damage to its overload.
Q:How to choose the pressure switch
The pressure switch can be divided into mechanical and electronic sub- First confirm that you need to confirm the type of switch 1. mechanical 2. Electronic If mechanical pressure switches are selected, the following parameters need to be confirmed 1. Switch range 2. Switch lag 3. Body material 4. Switch function: normally open or normally closed or single pole double throw 5. Interface size 6. Dielectric temperature 7. Electrical connection form: 8. Protection class:
Q:Is the pressure switch used?
Pressure switch is a commonly used switching instrument, in a number of industries have a certain application. It controls the flow of traffic and block, this switch is very important. The following are the same as the " Reference: Baidu search Ai Chi mall, inside the knowledge base has a very comprehensive industrial learning materials and complete product solutions, but also to meet your procurement Please also please, thank you
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:What parameters are required for pressure switch selection?
4. Output form (SPDT, DPDT, two SPDT) 5. Whether to require explosion protection 6. What is the total process connection
Q:Where the fire pressure switch is installed
The pressure switch is an indispensable part of the alarm valve. When the pressure in the sprinkler network is less than the steady pressure of the roof tank, the pressure switch can transmit the signal to the alarm host (if the pump is open automatically) and start the spray pump
Q:Pressure switch switching value problem
Switching is the difference between the upper limit of the measurement range and the next line only, the specific you can ask to buy the pressure switch manufacturers, KFP50 pressure switch you can refer to these data
Q:Have the air compressor changed the pressure switch or the hole leak?
The hole is put the head of the pressure on the release of no gas out, if the gas out for a long time then you can determine the one-way valve is broken. Open the one-way valve inside the valve plate wear or grinding or a change. Welcome to your service
