Falling object cooling type junction box for electrical equipment

Abstract

The invention discloses a falling object cooling type junction box for electrical equipment, and belongs to the technical field of junction boxs. According to the junction box, due to the arrangement of a normally-fixed hot soft body, a sleeving cooling piece, a heat absorption cooling ball and the like, when the temperature of an electric wire is too high, the normally-fixed hot soft body synchronous with the temperature of the electric wire is heated to be softened, and part of a reflective reminding rod falls into a transparent pipe. The reflective performance of the reflective reminding rod can play a reminding role, so that a worker can timely find the abnormal temperature phenomenon of the electric wire, further deterioration of an accident is prevented, meanwhile, a connector sleeving box and an electric wire sleeving block can fall downwards and sleeve an electric wire connector and an electric wire respectively, and a normally-closed ball outlet gap falls into clear water. Therefore, an effect of cooling the electric wire and the electric wire connector is provided, the temperature of the electric wire can be prevented from further rising within a certain time, the influence on other electric wires can be reduced, and the safety and the practicability are greatly improved.

Description

technical field [0001] The invention relates to the technical field of junction boxes, and more specifically, to a junction box for electrical equipment of falling object cooling type. Background technique [0002] Electrical equipment is a general term for generators, transformers, power lines, circuit breakers and other equipment in the power system. The important role played by electricity in our life and production cannot be ignored. It brings us great convenience and becomes an important energy source in our production and life. The most critical element in a power plant for the proper operation and delivery of electricity is the electrical equipment. [0003] Electrical equipment needs to use wires to power on. Therefore, it is often necessary to use a junction box to arrange the wires. The junction box is one of the electrical accessories, which plays the role of protecting the wires and connecting the wires. There are usually multiple wires in the junction box. Con...

AI Technical Summary

Problems solved by technology

[0004] During the power-on process, the wires are likely to be too hot due to reasons such as too dense arrangement, poor ventilation and heat dissipation, excessive load, and improper model selection, which may exceed the normal operating temperature. The junction box in the prior art, when a certain wire When the temperature of the wire on the connector is too high, it is impossible to give a reminder, so that the relevant staff cannot find the overheating phenomenon of the wire in time, and the temperature of the wire is likely to rise further. There are many wires in the junction box, and the wires with abnormal temperature will also affect the rest of the wires, causing the temperature of the rest of the wires to rise accordingly, which is easy to expand the scope of the accident, low safety performance, and poor practicability
