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:Air conditioning pressure switch has several lines, what is the line
There are three lines, red line, blue line, yellow line
Q:Control the pressure switch of the cold and dry machine fan is measured what pressure
In the cold and dry refrigeration system, the temperature and pressure are one by one, when the temperature is high when the pressure is also large.
Q:13 years Audi a6l oil pressure switch for lower oil pressure failure
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:How do I adjust the pressure switch of the electric pressure cooker?
Find the mechanical temperature sensor, scrape off the adjustment screw. If the exhaust does not jump insulation clockwise fine-tuning; if the pressure is not enough to jump insulation counterclockwise fine-tuning. Adjusted in 1 4 to 1 2 laps. Hope to help you 囧
Q:Is there a pressure switch with pressure relief function?
Pressure switch is a measuring element, its own will not have a pressure relief function, for automatic pressure relief can be connected to the pressure switch contacts components of the circuit (such as throttle, solenoid valve, variable frequency motor, regulating valve, etc.) through Chain protection function for pressure relief If helpful to adopt
Q:With the pressure switch diaphragm pump can install the governor
It appears that the pressure switch controls the diaphragm pump and the pump automatically starts or stops when the set pressure is reached. Is the switch control start and stop.
Q:Air conditioning pressure switch damage will be what failure
Usually the pressure switch is connected to the compressor power supply, if damaged, one situation is the compressor can not work, the other case the compressor will always work, even if the system pressure is too high, if the system pressure is too high, and compression Machine to continue working, then easy to damage the compressor.
Q:Is the booster pump pressure switch available at the repair shop?
Directly looking for aftermarket? Responsible for the sale of units are generally sales units.
Q:The pressure switch of all intelligent electric pressure cooker
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.
Q:SMC pressure switch "reverse" What does it mean? Negative output when?
In fact, the output signal is often open the meaning of normally closed
