Problems solved by technology

[0002] In the existing technology, the overcurrent protector is an externally purchased component. After entering the factory, the quality of the overcurrent protector can only be determined by visual inspection of the surface or after assembly of the finished product.
[0003] However, there is no device for detecting whether the overcurrent protector exists, and it is difficult to judge whether the overcurrent protector is qualified.
When there is a failure, it is necessary to increase the cost of man-hours by 40% for repair and replacement

Abstract

The invention discloses an overcurrent protector detection device, comprising an overcurrent protector circuit, wherein the circuit comprises an alternating-current wiring terminal, the alternating-current wiring terminal is connected with a power supply total toggle switch, a voltage regulator and a primary coil of a transformer in series in sequence, the secondary coil of the transformer is connected with a rectifier, the output end of the rectifier is connected with a direct-current voltmeter in parallel and is connected with an alternating-current contactor switch, a direct-current ampere meter, a test socket and an adjustable resistor in series in sequence, and a pedal switch is further connected between the alternating-current contactor switch and the power supply total toggle switch. Accordingly, the overcurrent protector detection device has he advantages of convenience for detection and low cost.

Description

technical field [0001] The invention relates to a detection device, in particular to a detection device for an overcurrent protector. Background technique [0002] In the existing technology, the overcurrent protector is an externally purchased component. After entering the factory, the quality of the overcurrent protector can only be determined through visual inspection of the surface or after assembly of the finished product. [0003] And there is no device for detecting whether the problem exists in the overcurrent protector, so it is difficult to judge whether the overcurrent protector is qualified at this time. When there is a failure, it is necessary to increase the cost of man-hours by 40% for repair and replacement. Contents of the invention [0004] In view of the above-mentioned defects in the prior art, the object of the present invention is to provide a detection device for an overcurrent protector with convenient detection and low cost. [0005] To achieve t...
