Problems solved by technology

[0006] As can be seen from the above, the clutch structure in the existing electromechanical operation type chassis vehicles is relatively complicated, and the manufacturing cost is relatively high.
Certain types of clutches cannot be disengaged automatically, which makes it very inconvenient for users to operate, and there are also situations where misoperation or overoperation causes damage to parts

Abstract

The invention provides an electromechanically operated chassis for a breaker. The chassis comprises a static frame, a mobile frame, a lead screw, a dynamic system, a power transmission system and an automatic clutch, wherein the breaker is placed on the mobile frame; the lead screw is rotatably mounted on the static frame; the mobile frame is mounted on the lead screw, and when the lead screw rotates, the mobile frame can be moved relative to the static frame along the axial direction of the lead screw; the dynamic system is mounted on the mobile frame; the power transmission system is used for transferring the power of the dynamical system to the lead screw so as to push in or draw out the mobile frame; the automatic clutch is arranged between the dynamical system and the power transmission system; and the automatic clutch is a centrifugal clutch. The electromechanically operated chassis for the breaker has the advantages of simple structure, easy operation and outstanding economical efficiency.

Description

technical field [0001] The present invention relates to low-voltage and medium-voltage electrical equipment, in particular to an electromechanical operation type chassis vehicle with automatic clutch for medium-voltage circuit breakers. Background technique [0002] In the medium-voltage electrical field, ordinary skilled persons know that in order to push or pull the circuit breaker to move between the working position and the test position, generally a chassis is used to carry the circuit breaker. At present, in terms of the operating structure of chassis vehicles, they can be roughly divided into mechanically operated chassis vehicles and electromechanical operated chassis vehicles. [0003] In mechanically operated chassis, the breaker is pushed in or pulled out using a direct combination of the handle and lead screw. Thus, no clutch is required. In the electromechanical operation chassis, the clutch is generally used to combine the power of the electric motor with the...
