Embodiment 1

[0036] Such as Figure 1-Figure 2 As shown, the embodiment of the present invention provides a power-taking structure of a switching device, including a moving contact group 1; the moving contact group 1 includes a first contact part 11 and a second contact part 12; the first contact part 11 can communicate with the incoming line side 21 of the control circuit 2 when the switch body is closed, so that the switch body can take power from the incoming line side 21 of the control circuit 2; the second contact part 12 can be connected with the The outlet side 22 of the control circuit 2 is connected, so that the switch body takes power from the outlet side 22 of the control circuit 2 .

[0037] Specifically, since the first contact part 11 and the second contact part 12 included in the movable contact group 1 respectively take power from the incoming line side 21 and the outgoing line side 22 of the control circuit 2 when the switch body is opened and closed, realizing When the s...

Embodiment 2

[0072] Such as Figure 4-Figure 5 As shown, the embodiment of the present invention provides a power-taking structure of a switching device, the difference from Embodiment 1: the height of the first contact arm 14 is higher than the height of the second contact arm 15, and the first contact arm 14 is higher than the second contact arm 15, and the first A contact part 11 is located at the end of the first contact arm 14, and the second contact part 12 is located at the end of the second contact arm 15, so that when the contact seat 13 moves, The first contact part 11 and the second contact part 12 respectively communicate with the incoming line side 21 and the outgoing line side 22 of the control circuit 2 in sequence.

[0073] Specifically, by making the height of the first contact arm 14 higher than the height of the second contact arm 15, and setting the first contact part 11 and the second contact part 12 between the first contact arm 14 and the second contact part The upp...

Abstract

The invention provides an electricity taking structure of a switching device and the switching device. The electricity taking structure comprises a movable contact group. The movable contact group comprises a first contact part and a second contact part. The first contact part can be communicated with the wire inlet side of a control loop when a switch body is closed, so that the switch body takes electricity from the wire inlet side of the control loop; and the second contact part can be communicated with the wire outlet side of the control loop when the switch body is disconnected, so that the switch body takes electricity from the wire outlet side of the control loop. The problem that energy cannot be provided due to faults when an existing switching device locally takes electricity at the wire inlet side of a control loop is solved. Local electricity taking is achieved through the control loop, electricity taking can be conducted from the wire inlet side and the wire outlet side of the control loop through the arranged first contact part and the arranged second contact part when the switch is switched off and switched on, the problem that power cannot be supplied when the control loop breaks down is avoided, the influence on the switch body is avoided, and the use continuity and reliability of the switching device are improved.

Description

technical field [0001] The invention belongs to the technical field of electric power equipment, and in particular relates to a power-taking structure of a switching device and the switching device. Background technique [0002] Switching appliances refer to switches used in low-voltage electrical appliances to connect and break circuits. In intelligent circuit breakers, control and protection switch products, external power supply is basically used to ensure the energy required for product opening and closing. [0003] When the existing switchgear takes external power, one is to use external wiring, which causes the problems of too many complicated lines and poor reliability. The method not only has the problem of poor reliability, but also cannot guarantee the continuity. [0004] In order to avoid the problem of poor reliability and continuity of the external power supply, the switchgear can also be powered locally. In the event of a fault such as a short circuit, there...
