Problems solved by technology

[0002] At present, the detection of electrical circuits in relay boxes, contactor boxes, etc. generally uses a multimeter, which is very inconvenient to use and has low detection efficiency. The circuit inside is more complicated, and the detection is more difficult and time-consuming
Especially when detecting the work (normally open) and release (normally closed) of the relay circuit, live operation is often required. During the detection, it is inevitable that a short circuit will occur due to the wrong contact point, burn out the electrical components, and even damage the equipment in severe cases.

Embodiment Construction

[0017] The present invention will be described below in conjunction with the accompanying drawings.

[0018] figure 1 The overall structure of the invention shown. It is mainly composed of a bridge rectifier circuit (1), a combination detection unit (2) and a connector (3). Several groups of combined detection units (2) are arranged to be connected in parallel. Combined detection unit (2) consists of K 1 、K 2 、K 3 It is composed of three switches and one indicator light. K of each combined detection unit (2) 1 、K 2 and K 3 One end is connected and connected with the corresponding unit number of the connector (3), and the connector (3) can be connected with several different connectors in parallel according to the different types of the tested parts (4). K 1 and K 2 There is an indicator light directly between the other ends, K 1 Connect with the self-test button, the self-test button is connected with the negative pole of the bridge rectifier (1) circuit, K 2 Conn...

Abstract

The invention relates to the electric appliance circuit testing technical field. The invention mainly comprises a bridge rectifier circuit, a self-check button, combined detecting elements, a connector, etc., which are connected in parallel by a plurality of groups of combined detecting elements. The combined detecting element group is composed of three switches and an indicator light. The invention detects a relay circuit by a mode of connecting a plug of the connector and a socket of the connector of a detected element, and avoids short circuit or misjudgement caused by touching contacts by mistake; the invention is of simple circuit structure, convenient using and operation, and improvement of working efficiency.

Description

Technical field: [0001] The invention relates to the technical field of electrical circuit testing, in particular to a detection device and method for detecting whether the relay circuit is connected correctly and works normally. technical background: [0002] At present, the detection of electrical circuits in relay boxes, contactor boxes, etc. generally uses a multimeter, which is very inconvenient to use and has low detection efficiency. The circuit inside is more complicated, and the detection is more difficult and time-consuming. Especially when detecting the work (normally open) and release (normally closed) of the relay circuit, live operation is often required. During the detection, it is inevitable to cause a short circuit due to wrong contacts, burn out the electrical components, and even damage the equipment in severe cases. Invention content: [0003] Technical problem to be solved: [0004] In order to solve the above problems, the present invention provides...
