Pre-assembled transformer box type transformer

The main components of the landscape box transformer combined substation: transformer, high-voltage switchgear and control equipment, low-voltage switchgear and control equipment, corresponding internal connecting lines (cables, busbars and others) and auxiliary devices. The combined transformer box transformer is connected by cable and can be operated from its inside or outside, capable of being installed on or below ground (partially or fully). Widely used for 6KV/6.3KV/7.2KV/10KV/12KV/22KV

/24KV/33KV/35KV/40.5KV box-type transformer distribution switchgear, urban power grid transformation, residential areas, high-rise buildings, industrial and mining, hotels, shopping malls, airports, railways, oil fields, docks, highways and temporary power installations and other indoor and outdoor places.

The variable high voltage part of this box adopts high-voltage vacuum circuit breaker (VS1), microcomputer comprehensive protection or high-voltage load switch, insertion fuse, backup current limiting fuse and other high-voltage components. It is connected by high-voltage distribution device, transformer and low-voltage distribution device, divided into three functional isolation, namely high-voltage room, transformer room and low-voltage room, high and low voltage outdoor functions are complete, high-voltage measurement primary power supply system, can be arranged into ring network power supply, terminal power supply, dual power supply and other power supply methods, can also be installed high-voltage metering components to meet the needs of high-voltage measurement. The transformer room can choose dry-type transformers and other series of low-loss oil-immersed transformers or dry-type transformers; The low-voltage chamber can be composed of panel or switchgear-mounted structure according to user requirements to form the power supply scheme required by the user, and has a variety of functions such as power distribution, lighting distribution, reactive power compensation, energy measurement and power measurement to meet the different requirements of users. And facilitate the user's power supply management and improve the quality of power supply;

→ high pressure chamber has a compact and reasonable structure, and has a comprehensive anti-misoperation joint pin function. When the user has the requirements, the transformer can be equipped with a track to easily enter and exit from the doors on both sides of the transformer room. Each room has automatic lighting devices, and all components selected in the high and low pressure chambers have reliable performance, easy operation, safe and reliable product operation and convenient maintenance;

→ two methods: natural ventilation and forced ventilation. The transformer room and the high and low voltage rooms have ventilation channels, and the exhaust fan has a temperature control device that automatically starts and closes according to the set temperature to ensure the normal operation of the transformer;

→ box structure can prevent rain and dirt from entering, and the material is made of colored steel plate, which has anti-corrosion and heat insulation function. With long-term outdoor use conditions, to ensure anti-corrosion, waterproof, dustproof performance, long service life, Tongjin beautiful appearance.
