Description

Electrical safety detection device and detection equipment

Technical Field

The utility model belongs to the technical field of electric safety detection, and particularly relates to an electric safety detection device and detection equipment.

Background

In the electrical appliance processing and manufacturing industry, electrical appliances are usually required to be electrically detected before leaving the factory, and the electrical appliances can be packaged and leave the factory only after the electrical detection is qualified. The following describes a general description of a conventional electrical inspection tool and an inspection operation process, taking an electrical inspection before shipping of an air conditioner outdoor unit as an example.

In order to facilitate centralized management of wiring and circuits during use, the wiring terminals of various current electrical appliances are generally arranged in a terminal groove in a centralized manner. The existing detection tool mainly comprises an electrical safety performance tester and a connecting wire; the electric safety performance tester can detect four main electric safety data such as insulation, leakage, withstand voltage and grounding of the air conditioner outdoor unit, compares the four main electric safety data with a set safety value, and gives an alarm to prompt a worker when any one of the related data is abnormal, but the detected electric appliance has a problem, and the worker needs to manually take off the line to repair the problem machine.

When detecting, one end of each connecting wire is connected with a corresponding terminal of an electrical safety performance tester in advance, the other end of the relevant connecting wire for insulation, leakage and pressure resistance detection needs to be manually connected to a corresponding connecting terminal of the detected air conditioner outdoor unit by a worker, and the other end of the relevant connecting wire for ground detection is manually clamped on a stop valve of the air conditioner outdoor unit by the worker. Every time an air conditioner outdoor unit is detected, a wiring operation needs to be manually performed. After each connection is completed, an electrical safety performance tester is started (or the tester can be set to be in a self-starting mode after connection), and the tester detects electrical safety.

The detection process needs repeated single wiring operation of manpower and long-time machinery, and the labor intensity is high; in addition, if the wiring terminal is not connected with the air conditioner outdoor unit correctly during detection, inaccurate detection data, false detection and false alarm can be caused, and the reliability is not high; in addition, the working voltage is larger during detection, and potential safety hazards still exist although staff stand on the insulating rubber in actual operation.
