A test device for bipolar leakage protection switch

Abstract

The invention provides a test device for a bipolar leakage protection switch, which cooperates with a first bipolar leakage protection switch, and includes a second bipolar leakage protection switch, a bypass switch, a first and a second display part; The second bipolar leakage protection switch includes a live wire input terminal connected to the first bipolar leakage protection switch, a neutral line input terminal connected to the first bipolar leakage protection switch, and a live wire output terminal connected to the first end of the first display component, The neutral line output end connected with the second end of the first display part; the bypass switch includes one end connected with the ground wire and the other end connected with the second end of the second display part; the second display part also includes a connection with the second bipolar The live wire output end of the leakage protection switch and the first end of the first display component are both connected to the first end. The implementation of the present invention can effectively test the operation reliability of the double-pole leakage protection switch in the user's home, judge the correctness of the power connection mode, and realize the purpose of eliminating potential safety hazards and preventing power safety accidents.

Description

technical field [0001] The invention relates to the technical field of leakage protection switches, in particular to a test device for bipolar leakage protection switches. Background technique [0002] With the increase of users' household electrical equipment, the user's electricity load has also increased, and safety problems such as electric shocks caused by leakage, burning of electrical appliances, and even fires have become more and more prominent. Household leakage protection switch, as the "first protector" of the user's electricity safety, its performance and quality play an important role in improving the level of safe electricity use, reducing personal electric shock casualties, equipment leakage protection and electrical fire accidents. [0003] At present, because the user's electricity voltage generally adopts single-phase 220V, most users use bipolar two-wire leakage protection switches in their homes. The quality is also mixed, so it is difficult for most ho...

Problems solved by technology

[0003] At present, because the user's electricity voltage generally adopts single-phase 220V, most users use bipolar two-wire leakage protection switches in their homes. The quality is also mixed, so it is difficult for most household leakage protection switches to achieve the purpose of leakage protection and overload prevention; 2. Since most electricity users lack the maintenance awareness of leakage switches, they cannot perform regular test trips, which leads to aging of leakage switches. Sensitivity and other problems occur from time to time; 3. Due to the variety of low-voltage wiring methods in the user's home, there are wrong wirings such as connecting the N wire (zero wire) and the PE wire (ground wire) in parallel, and swapping the L wire (fire wire) and N wire at the socket. situation, making the leakage switch lose its function
