Metal armouring medium voltage switchgear cabinet is a three-phase AC 50HZ indoor power distribution device, which is used to receive and distribute 3-12KV network electric energy and implement control protection and monitoring of the circuit. The relay chamber panel of the metal armouring medium voltage switchgear cabinet can be installed on various types of microcomputer integrated relay protection device, and can realize the intelligent control system, with remote control, remote measurement, remote communication and remote adjustment function, The CAN bus with a communication interface is used to control the field network and has "five preventions" functions to ensure safety, which include: Preventing the mis-operation of circuit breakers, Preventing the movement of a load-bearing trolley, Preventing the closing of grounding switches with live voltage, Preventing the earthing switch from transmitting power at the grounding position and preventing the inadvertent entry into the live interval. These "five preventions" functions are crucial for maintaining safety in electrical systems. The cabinet can be equipped with VS1 (ZN63) ZN12V vacuum circuit breaker, and can also be equipped with imported VD4 vacuum circuit breaker and VC series vacuum contactor.

 

 

 

 

• Environment air temperature · Upper limit +40°C, lower limit - general area -10°C
• Altitude: 1000m
• Relative humidity: daily average no more than 95%, monthly average no more than 90%
• Water vapor pressure: The average daily value is no more than 2.2 Kpa and the average monthly value is no more than 1.8 Kpa.
• Condensation may occur when the temperature drops sharply, accompanied by pollution, this product is suitable for the following two environmental conditions that are harsher than normal conditions: condensation is not frequent (no more than twice a month on average) and there is mild pollution; Generally there is no condensation (no more than twice a year on average) with more serious pollution
• There is no danger of fire, explosion and severe pollution enough to corrode metal and destroy insulation and other harsh places
• There is no severe vibration, turbulence and the vertical inclination does not exceed 8°;

Note:

1. Allows storage and transportation at -30°C.
2. When the altitude more than 1000m, according to JB/Z102 "High voltage electrical equipment use altitude area technical requirements" treatment, when the altitude does not exceed 2000m, low voltage auxiliary equipment does not need to take any measures.
3. When the actual conditions of use are different from the above, the user and the manufacturer shall negotiate.

 

 

Metal armouring medium voltage switchgear cabinet is composed of a fixed cabinet and a draw-out part (trolly). The cabinet shell and the partition of each functional unit are made of aluminum-zinc steel plate bolted together. The enclosure protection level of the switch cabinet reaches IP4X, and the protection level of each compartment is IP2X. The switch cabinet has overhead incoming and outgoing, cable incoming and outgoing and left and right contact functions. According to the purpose, the switch cabinet of each scheme can be arranged to form a power distribution device that can complete the design function. The installation and debugging of the switch cabinet can be carried out in the front, and can be against the wall, so as to save the floor area and reduce investment.
