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...

Embodiment Construction

[0021] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0022] like figure 1 As shown, it is a test device for a bipolar leakage protection switch provided by the embodiment of the present invention, which is matched with the first bipolar leakage protection switch connected to the live line L and the neutral line N in the user's home. The test device includes the first Two bipolar leakage protection switch M, bypass switch N, first display part L1 and second display part L2; wherein,

[0023] The second bipolar leakage protection switch M includes a live line input terminal m1 that can be connected to the first bipolar leakage protection switch through the live line L, and a neutral line input terminal m2 that can be connected to the first bipolar leakage protection switch through the neutral line N, and The live lin...
