Electrical control box temperature cycle test detection device

Abstract

The invention discloses an electrical control box temperature cycle test detection device which comprises a box body, a fixed ring is vertically installed in the middle of an inner cavity of the box body, telescopic sections are connected to the two side walls of the fixed ring respectively, movable rings are fixed to the tail ends of the telescopic sections, and detection cavities are formed in the fixed ring, the telescopic sections and the movable rings. The telescopic sections are made of two telescopic rubber pipes with different diameters, and a through hole is formed in the surface of the telescopic rubber pipe located on the inner side. The fixed ring and the movable ring are arranged in the box body, the detection cavity is formed in the inner sides of the fixed ring and the movable ring, the space of the detection cavity is small, the temperature in the detection cavity is adjusted during detection, energy consumption is reduced, and the detection effect is improved; the control box is clamped and fixed through the fixed clamping plate and the movable clamping plate, a plurality of fixing mechanisms are arranged on the surfaces of the clamping plates, after the control box is fixed, slipping can be avoided, the fixing stability is improved, and the detection device is suitable for being used by control boxes of different specifications and wide in applicability.

Description

technical field [0001] The invention relates to the technical field of electric control box detection, and more specifically relates to a temperature cycle test detection device for an electric control box. Background technique [0002] The control box is suitable for opening factories, mines, enterprises, shopping malls, hotels, schools, airports, ports, hospitals, high-rise buildings, living quarters, etc., in the low-voltage power grid system with AC 50HZ and rated working voltage of AC 380V, as power, lighting distribution and Used for motor control, suitable for indoor wall-mounted and outdoor floor-mounted power distribution equipment. It is also used in AC 50HZ, voltage below 500V power system as fire pump control, submersible pump control, fire fan control, fan control, lighting distribution control, etc. The control methods include direct start control, star delta step-down start control, self-coupling Various control methods such as step-down start control, invert...

AI Technical Summary

Problems solved by technology

[0003] At present, the internal space of the existing electric control box temperature cycle test detection device is relatively large, the temperature of each position inside the detection device is inconsistent, and the detection effect is poor. When testing, the inside of the box needs to be filled to achieve the detection. Effect, the energy consumption of the equipment is high, and it is not convenient to fix the control box
