Henan transformer ring cabinet manufacturer

lifting cabinet: because the high-voltage cabinet is different from the low-voltage cabinet, the electrical clearance of the high-voltage cabinet should be greater than that of the low-voltage cabinet. In order to ensure the clearance, one such lifting cabinet should be added (some lifting cabinets are also equipped with disconnectors). Transformer cabinet: a 20 or 50KVA transformer is installed inside, which is used to supply the power for the substation itself. Outgoing cabinet: the power supply is output from this cabinet, which generally has the functions of breaking, isolation and various protection functions (overcurrent, quick break, overvoltage, undervoltage, zero sequence, differential, locked rotor, etc., which can be configured according to the needs of the protected equipment). Capacitor compensation cabinet: it compensates reactive power, improves power quality, reduces loss, and provides distribution operation data

Shanxi jintaiheng Technology Co., Ltd. takes safety and stability as its own responsibility, with low product failure rate and no quality problems for many years. Today, jintaiheng Technology Co., Ltd. will share with you the relevant knowledge of the ring cabinet: the grounding switch is composed of a dynamic contact knife and a static contact knife. During the spring movement, the grounding switch can only be quickly switched on by replacing the sensor. Four rectangular assembly process holes are opened at the upper and rear of the switch room. The front of the ring cabinet is equipped with an observation window to see the "open" and "close" positions of the grounding switch. Explosion proof device is installed at the rear of the ring cabinet. The load switch adopts the compressed air internal blowing structure, which has strong arc extinguishing ability and does not affect the phase to phase and ground insulation. Both the dynamic and static contacts are equipped with arc contacts, which greatly improves the breaking times

in order to meet the requirements of distribution automation and improve distribution reliability, Henan transformer ring cabinet manufacturer can add electric mechanism, TV and distribution control terminal unit as required, with three remote functions

both EPS power supply and UPS power supply of Henan transformer ring cabinet manufacturer have mains bypass and inverter circuit. The functional difference is that EPS power supply has the function of continuous power supply, which generally does not require high inverter switching time, and has certain requirements for applications in special occasions

gck low-voltage switchgear has high breaking ability, good dynamic and thermal stability, advanced and reasonable structure. GCK drawer type distribution cabinet has flexible electrical scheme, strong seriality and versatility, and various scheme units are arbitrarily combined. 3. For the sampling of rolled profiles or forgings, consider whether the surface layer has decarburization, folding and other defects. A cabinet body. The drawer has the advantages of large number of circuits, saving floor space, high protection level, safety and reliability, convenient maintenance, etc. the drawer is divided into 1/2 unit, 1 unit, 2 unit and 3 unit, which can be installed with 9 single high reliability units, and the cabinet can be installed with 18 units. The drawer has the directions of closing, opening, testing and drawing out, which can not only ensure the normal work, but also safely overhaul the components in the drawer. From the pushing method of the drawer, it is basically divided into single pull-in type, double pull-in type and swing in type

drawer type switchgear. This kind of switch cabinet is made of closed shell made of steel plate, and the electrical components of incoming and outgoing circuit are installed in withdrawable drawers to form a functional unit that can complete a certain type of power supply task. The functional units are separated from the bus or cables by grounded metal plates or functional plates made of plastic to form three areas of bus, functional units and cables. There are also isolation measures between each functional unit. Drawer type switchgear has high reliability, safety and interchangeability. It is a relatively advanced switchgear. Most of the produced switchgear are drawer type switchgear. They are applicable to industrial and mining enterprises and high-rise buildings that require high power supply reliability, and serve as centralized control power distribution centers
