A circuit breaker interlocking handcart

Abstract

The invention discloses a circuit breaker interlocked rocking-in handcart, which solves the problem that interlocking of the existing rocking-in handcart is not reliable in the actual working process. The circuit breaker interlocked rocking-in handcart comprises an end beam, a cart body, a driving rod and a driving piece for driving the driving rod to rotate, wherein the cart body is internally provided with an auxiliary switch and an interlocking plate; the driving rod is connected with the auxiliary switch through a first transmission mechanism and a second transmission mechanism; the first transmission mechanism is in linked connection with a first linkage plate; the second transmission mechanism is in linked connection with a second linkage plate; and the interlocking plate is provided with a first position limited by the first linkage plate, a second position interlocked with the circuit breaker for avoiding error operation of the circuit breaker, and a third position limited by the second linkage plate. Arrangement of a left plate is reduced, the interlocking plate driving mode is simplified, the production cost is reduced, the structure is simple, the assembly is convenient, the actions are reliable, and the service life is long.

Description

technical field [0001] The invention relates to a switch cabinet, in particular to a circuit breaker interlocking handcart. Background technique [0002] With the advancement of power equipment manufacturing technology, the power supply device of power equipment is becoming more and more stable. In order to further improve the automation of the power industry, various units in the power supply industry have comprehensively launched unattended transformation of substations. [0003] In the existing center-mounted insulated switchgear, in order to enable the center-mounted vacuum circuit breaker to conveniently realize the functions of pushing in (pushing from the test position into the working position and interlocking) and withdrawing (exiting from the working position to the test position and interlocking) Generally, a cranking handcart or chassis car is used to carry the vacuum circuit breaker, and the driving wheels mounted on the cranking handcart move forward or backwar...
