Description

Prefabricated box-type substation

Technical Field

The utility model relates to the technical field of power distribution devices, in particular to a prefabricated box-type transformer substation.

Background

In modern power systems, prefabricated box substations are widely used because of their modular, quick deployment and easy maintenance characteristics, which generally require handling of large amounts of wires and cables to ensure stable transmission of power, whereas wires and cables are generally loosely suspended in the equipment in conventional designs, such unordered arrangements may increase the difficulty of maintenance and replacement, increase maintenance costs and time, and even lead to wear and damage of the cables, increasing the risk of short circuits and fires.

The use of prefabricated box substations in modern power systems is already quite widespread. However, such substations need to operate under various environmental conditions, including heavy weather conditions such as heavy rain, snow, and even floods. Thus, the waterproof problem is a factor that must be considered seriously when designing and manufacturing prefabricated box substations. However, the waterproof design of the existing box-type substation mainly depends on the tightness of the box body and the protection measures at the wire inlet, which results in relatively poor waterproof sealing performance. Such design imperfections may affect the normal use of the device.

Prefabricated box substations generally comprise electrical equipment such as transformers, switching equipment, control systems, etc., which are assembled in a box and can be quickly installed and deployed when required, however, heat generated during operation may affect the performance and lifetime of the equipment if not effectively dissipated, and thus ventilation management is critical in design and operation, while humid environments may lead to internal humidity, which in turn affects the normal operation of the equipment.
