Problems solved by technology

[0002] Existing arc protector products realize the arc protection function by putting the sensor outside a certain wire to be protected, and sometimes even need more than two sensors. sensor, resulting in complex structure of the product, inconvenient use, and increased production cost of the product
[0003] In addition, the existing arc protector needs more sensors to realize the three-phase arc protection function, which further increases the cost of use and is difficult to use

Abstract

A leakage and arc protector with a single sensor can simultaneously realize two functions of leakage protection and arc protection only by a leakage sensor. In addition, the arc protector has no limitation on the number of the electric wires to be protected, and the electric wires can be either single-phase or three-phase, but the circuit is not added with elements while all the electric wires to be protected are only needed to perforate the sensor. Therefore, the leakage sensor greatly reduces the manufacturing cost and use cost of the product, and improves the usability of the product for a user using the product.

Description

Technical field [0001] The invention relates to a leakage and arc protector, in particular to a single-sensor leakage arc protector that only needs one leakage sensor and can realize the two functions of leakage and arc protection at the same time. Background technique [0002] The existing arc protector products realize the arc protection function by putting the sensor outside a certain wire that needs to be protected, and sometimes even more than two sensors are needed. If the leakage protection function is to be realized at the same time, then a leakage protection is needed. The sensor causes complex structure of the product, inconvenient use, and increases the production cost of the product. [0003] In addition, the existing arc protector needs more sensors to realize the three-phase arc protection function, which increases the use cost and the degree of difficulty in use. Summary of the invention [0004] The purpose of the present invention is to solve the above-mentioned...
