High- and low-voltage power distribution cabinet capable of being automatically powered off when overheated

Abstract

The invention discloses a high- and low-voltage power distribution cabinet capable of being automatically powered off when overheated. The high- and low-voltage power distribution cabinet comprises acabinet body, wherein limitation racks are fixedly connected to the top and the bottom of two sides of an inner wall of the cabinet body, one end of each limitation rack is fixedly connected with thetop and the bottom of two sides of an outer surface of a placement box, temperature sensors are clamped in inner cavities of two sides of the top and the bottom of the placement box, and middle partsof inner cavities of the four temperature sensors are clamped with alarm lamps. In the high- and low-voltage power distribution cabinet capable of being automatically powered off when overheated, a temperature in the cabinet can be detected in real time by the temperature sensors, detection and comparison are performed by a detection module and a comparison module, the alarm lamp can be controlledto be flicking when the compared data is excessively large, warning processing is performed, the running of a circuit breaker and a knife switch are controlled according to heat of the temperature, the switch can be switched off by the circuit breaker when the heat is medium and can be directly cut off by the knife switch when the heat is excessively high, and the safety is greatly improved.

Description

technical field [0001] The invention relates to the technical field of power distribution equipment, in particular to a high and low voltage power distribution cabinet that automatically cuts off power when overheated. Background technique [0002] The power distribution cabinet (box) is divided into power distribution cabinet (box), lighting distribution cabinet (box), metering cabinet (box), and is the final equipment of the power distribution system. The power distribution cabinet is a general term for the motor control center. The power distribution cabinet is used in the occasions where the load is relatively scattered and there are few circuits; the motor control center is used in the occasions where the load is concentrated and there are many circuits. They distribute the electric energy of a certain circuit of the upper-level power distribution equipment to the nearest load. This level of equipment shall provide protection, monitoring and control of the load. [0...

AI Technical Summary

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a high-voltage and low-voltage power distribution cabinet with overheating and automatic power-off, which has the function of overheating and automatic power-off, can greatly improve the safety performance of the power distribution cabinet during use, and solves the problems in the cabinet. When the heat inside is too high, automatic power-off cannot be performed, which will lead to the occurrence of safety accidents
