Embodiment Construction

[0034] The technical solutions of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Apparently, the described embodiments are some of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0035] In addition, the technical features involved in the different embodiments of the present invention described below may be combined with each other as long as there is no conflict with each other.

[0036] Such as Figure 1-6 As shown, it is a specific implementation of a reclosing device involved in the present invention. The reclosing device is used to trip when overload, overcurrent or short circuit occurs in the circuit, and push the operating mechanism to buckle after the fault is eliminated. close...

Abstract

The invention relates to the technical field of switches, in particular to a reclosing device. The reclosing device comprises a shell, a drive motor, a transmission mechanism and an automatic closingmechanism and is characterized in that the drive motor is arranged inside the shell, the transmission mechanism is in linkage with the drive motor, the automatic closing mechanism allows an operationmechanism to close under the effect of the transmission mechanism, the transmission mechanism is provided with a rotary face whose axial height gradually increases under the driving of the drive motor, the automatic closing mechanism is slidably arranged on the rotary face, and the automatic closing mechanism continuously acts on the operation mechanism during the rotation of the transmission mechanism to allow the operation mechanism to complete closing. The reclosing device has the advantages that the closing mechanism, for driving the closing, of the reclosing device is continuous and stable in acting force, and timely and reliable closing can be achieved.

Description

technical field [0001] The invention relates to the technical field of switches, in particular to a reclosing device. Background technique [0002] In the power supply and distribution system, there are a large number of unattended power distribution cabinets, and the switches trip when overloaded, overcurrented, or short-circuited. After the overload, overcurrent, and short circuit faults are eliminated, it is necessary to wait for personnel to close the switch, resulting in a long power outage and increasing the workload. In order to solve the above technical problems, the Chinese patent document CN205900480U discloses a small circuit breaker for automatic closing, which includes: a circuit breaker unit and a reclosing unit. The gate unit includes a first housing, the first housing is provided with a driving motor and a rotating part driven by the driving motor, and also includes a coupling part coaxial with the rotating part and a trip piece for pushing the trip pin . ...
