Embodiment Construction

[0021] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0022] Such as figure 1 As shown in the figure, a kind of mechanical transmission is applied to the moving mechanism of the handcart of the medium voltage circuit breaker. It drives the rotating shaft by shaking the external handle, installs a bevel gear on the transmission shaft, drives another bevel gear, and passes through the middle of the bevel gear with a hexagonal shaft. , install two gears on the second section of the shaft, install racks on both sides of the outer frame, and install wheels. There is a point fluctuation switch on the front frame. When the moving mechanism is pushed into the medium voltage electrical cabinet, Toggle the switch, there is a positioning pin on the frame, extend out and insert it directly into the medium voltage electrical cabinet, then shake the handle to drive the bevel gear, and mesh with another bevel gear. The b...

Abstract

The invention discloses a handcart mechanism of a circuit breaker. The handcart mechanism comprises an internal rack of a handcart and an external rack of the handcart, wherein the internal rack of the handcart is mainly used for positioning the handcart mechanism; the handcart is arranged in metal closed switch equipment for linkage; a vacuum circuit breaker is arranged on the external rack of the handcart; a panel directly displays the position, and with the conversion of stirring switches, the connection of an internal rack body and a cabinet body of the metal closed switch equipment can be locked; external rack wheels are arranged on the external rack; and when the vacuum circuit breaker which is arranged on the external rack enters a touch box by shaking, and a movable contact is jointed with a stationary contact, inclination can be avoided due to uniform forcing of two edges by meshing a gear and a rack. By adoption of the handcart mechanism of the circuit breaker, a medium-voltage circuit breaker can more steadily and reliably move. Compared with the conventional screw transmission technology, the handcart mechanism of the circuit breaker has the advantages of good stability, high reliability and convenience for use.

Description

technical field [0001] The invention relates to the balanced transmission technology of the handcart mechanism of the medium voltage circuit breaker, especially the handcart of the circuit breaker which adopts the combination of the bevel gear transmission structure and the rack, which can reduce the damage of the contact caused by the inclination of the contact during the contact process due to the movement. ACCIDENT. Background technique [0002] Medium-voltage circuit breakers are widely used in power transmission and distribution equipment, accounting for about 30% of all equipment. With the increasing use of medium-voltage circuit breakers, the large-scale use of medium-voltage circuit However, since the handcart of the vacuum circuit breaker is pushed into the electrical cabinet, a certain position must be reserved for the handcart of the medium voltage circuit breaker to be moved into the electrical cabinet, and the stability of the push-in needs to be ensured. At pr...
