Abstract

The invention is applicable to the technical field of electronic devices, and provides an air switch power-taking device for series and parallel connection of circuits. A first clamping wall and a second clamping wall can be clamped together in an air switch, an adjusting part can adjust the distance between the first clamping wall and the second clamping wall to adapt to the air switch with different interface spacing, and the applicability is high. After the first clamping wall and the second clamping wall clamp the air switch, electricity taking thimbles in two electricity taking units canmake contact with electric screw hole interfaces of the air switch, safe, firm and electric connection is achieved, the thimbles are connected with an external device through an external connection wire, electricity taking can be achieved under large load current, the two thimbles can make contact with the upper and lower electric screw hole interfaces of the air switch simultaneously to achieve circuit series connection and application. The combination of two air switch power-taking devices for series and parallel connection of circuits can meet the application requirement of series or parallel connection of an electrical circuit in detection, and line lead-out for electricity taking or detection can be conveniently achieved without changing the situation of circuits in a meter box.

Description

technical field [0001] The invention belongs to the technical field of electronic devices, and in particular relates to an air switch power-taking device used for series-parallel connection of lines. Background technique [0002] Air switch (air switch), also known as air circuit breaker, is a switch that will automatically disconnect as long as the current in the circuit exceeds the rated current. The air switch is a very important electrical appliance in the low-voltage power distribution network and electric drive system. It integrates control and multiple protection functions. In addition to completing the contact and breaking of the circuit, it can also protect the short circuit, severe overload and undervoltage of the circuit or electrical equipment, and can also be used to start the motor infrequently. [0003] In the low-voltage power distribution field inspection work in the power industry, it is often necessary to inspect the electric energy meter or the circuit. ...
