The patent application of the present invention is a divisional application of the invention patent titled "a vacuum circuit breaker transfer vehicle with adjustable width and height". The original application date was January 27, 2014, and the application number was 2014100400606.

technical field

The invention relates to a vacuum circuit breaker transfer vehicle with adjustable width and height.

Background technique

In the process of installation, commissioning, operation and maintenance of the central cabinet, it is necessary to use a transfer cart to safely transport the vacuum circuit breaker out of the central cabinet and place it in another location. The transfer carts currently on the market have several defects: 1. The height adjustment is slow, and it is very difficult to level the height of the front, rear, left, and right points. Unbalanced and easy to cause bolt deformation; 2. There are many height and width specifications, and the versatility is poor. Different specifications of circuit breakers must be equipped with corresponding transfer vehicles, which increases production costs. , which also caused a large amount of site space to be occupied; 3. There is no reliable locking device for the transfer vehicle and the vacuum circuit breaker, and the center of gravity of the transfer vehicle is too high. 4. Because there is no lifting equipment on site, sometimes the circuit breaker needs to be dropped from the transfer vehicle to the ground or lifted from the ground to the transfer vehicle. The transfer vehicle is high from the ground and the high-current circuit breaker is relatively Heavy, so useless. At present, it is becoming more and more difficult for power consumption departments to arrange power outage time. If the accident occurs during the on-site power consumption operation and maintenance stage, it may prolong the power outage time and cause greater economic losses.
