Lifting type buried ring main unit with constant-temperature and constant-humidity purification system

Abstract

The invention discloses a lifting type buried ring main unit with a constant-temperature and constant-humidity purification system. The lifting type buried ring main unit comprises a cabinet, a lifting type buried ring main unit body and a foundation pit. An evaporator, a compressor, a fan, a humidifier, an electric heater and a temperature and humidity controller are arranged in the cabinet. The cabinet is fixedly installed in a foundation pit, the evaporator is fixedly installed on the rear side of the bottom of the cabinet, the compressor is fixedly installed in the middle of the cabinet, the fan is fixedly installed on the upper right portion of the cabinet, the humidifiers are fixedly installed on the periphery of the cabinet, the electric heater is fixedly installed on the front side of the bottom of the cabinet, and the temperature and humidity controller is fixedly installed on the front side of the upper portion of the cabinet. According to the scheme, the problems that components are burnt out due to too high temperature and components are short-circuited due to too high humidity can be solved, the constant-temperature and constant-humidity purification system is additionally arranged on the ring main unit, so that the purpose of protecting the components and the ring main unit is achieved, and the ring main unit is simple in structure, easy to manufacture and install, not prone to damage, high in practicability and capable of being popularized in a large range.

Description

technical field [0001] The invention relates to the technical field of ring network cabinets, in particular to a lift-type buried ring network cabinet with a constant temperature and humidity purification system. Background technique [0002] The ring network cabinet is a group of electrical equipment for transmission and distribution that is installed in a metal or non-metal insulated cabinet or made into an assembled interval ring network power supply unit. Its core part uses load switches and fuses. It has simple structure, small size, It has the advantages of low price, improved power supply parameters and performance, and power supply security. It is widely used in distribution stations and box-type substations of load centers such as urban residential quarters, high-rise buildings, large public buildings, factories and enterprises. [0003] The structure of the lifting type buried ring network cabinet, in order to overcome the problems of not occupying urban roads, gr...

AI Technical Summary

Problems solved by technology

When the ring main unit is in the power supply state, the heat generated by the work cannot be dissipated in time. If the temperature is too high, the internal components will be easily damaged or even short-circuited; if the humidity is too high, a large amount of water vapor will accumulate inside to form Condensation can easily cause a short circuit and cause equipment failure
