Problems solved by technology

[0004] At present, most manufacturers use the following methods to detect leakage protectors PRCD: 1. Outsourced certification inspection and testing institutions for testing, but there are long test cycles and high test costs, and it is difficult to find and analyze test failures; 2. Outsourced equipment manufacturer testing machine , there are high equipment costs, poor applicability, and difficult maintenance
[0005] On the other hand, the existing overload detection device used for leakage protectors cannot perform self-inspection, and it is difficult to find out the error point if the detection error is made. Inaccurate

Abstract

The present invention discloses an earth leakage protection device overload testing device. The earth leakage protection device overload testing device is short in the overload test power-on time, employs a high-power transformer with the high loading capacity and provides 120V and 90-120A output so as to save the cost; the earth leakage protection device overload testing device with a self-inspection and testing product no-load debug function; and moreover, the earth leakage protection device overload testing device has a test data statistical analysis function and a test failure alarm function, and is simple in electrical line and convenient in maintenance, low in cost and low in test cost.

Description

[0001] [technical field] [0002] The invention relates to an overload testing device for a leakage protection device. [0003] [Background technique] [0004] At present, most manufacturers use the following methods to detect leakage protectors PRCD: 1. Outsourced certification inspection and testing institutions for testing, but there are long test cycles and high test costs, and it is difficult to find and analyze test failures; 2. Outsourced equipment manufacturer testing machine , there are high equipment costs, poor applicability, and difficult maintenance. [0005] On the other hand, the existing overload detection device used for leakage protectors cannot perform self-inspection, and it is difficult to find out the error point if the detection error is made. Inaccurate. [0006] [Content of the invention] [0007] The invention overcomes the disadvantages of the above-mentioned technologies, and provides an overload testing device for an intelligent leakage protectio...
