Problems solved by technology
At present, the upper workbench of the special-purpose maintenance handcart is an overall flat structure. Since the stroke sensor for measuring the opening and closing speed of the circuit breaker needs to be connected below the circuit breaker, when the circuit breaker is placed on the workbench of the handcart, the stroke cannot be connected. The sensor can only be connected and measured after lifting the circuit breaker with lifting equipment, which is not only time-consuming and laborious, but also requires special lifting equipment

Embodiment Construction
[0008] The present invention will be further described below in conjunction with accompanying drawing:
[0009] Such as figure 1 , 2 Shown, the present invention mainly is made of vehicle frame 1, wheel 2, and the workbench panel of vehicle frame top is made of two boards 5 and 6 that can slide along slideway 3,4, and the middle part of workbench panel is provided with square through-hole. Hole 7, two slideways are arranged in parallel on the vehicle frame of the bottom of the workbench panel by a certain interval, and the two ends of the slideway extend to a certain length outside the vehicle frame, and the two workbench panels can slide along the slideway, and can make The width of the panel is greater than the width of the frame.
[0010] When in use, slide the two workbench panels to a certain width according to the size of the circuit breaker, and then place the circuit breaker on the workbench panel for inspection and maintenance. The lower part connects the sensor to...

The invention relates to a vacuum circuit breaker maintenance handcart. The vacuum circuit breaker maintenance handcart comprises a cart frame and wheels and is characterized in that a working table face board on the upper portion of the cart frame is composed of two symmetric slidably-foldable boards, the middle of the working table face board is provided with a through hole, the cart frame on the lower portion of the working table face board is provided with slideways for the working table face board to slide, and the length of the slideways is larger than the width of the cart frame. The vacuum circuit breaker maintenance handcart is applicable to maintenance and detection of circuit breakers of various specifications and in different sizes and can directly perform connection of a travel sensor after a circuit breaker is placed to measure the data indexes such as the switch-on and switch-off speed of the circuit breaker, so that the circuit breaker does not need to be lifted up through a hoist device; meanwhile, the vacuum circuit breaker maintenance handcart is simple in structure and convenient to use.
Description
technical field [0001] The invention relates to an auxiliary tool for detecting high-voltage electrical equipment, in particular to a vacuum circuit breaker maintenance handcart. Background technique [0002] Vacuum circuit breakers are currently the most widely used high-voltage electrical equipment. During operation, the opening and closing speed of vacuum circuit breakers, opening and closing starting voltage, vacuum degree of arc extinguishing chamber, and loop resistance are directly related to the vacuum circuit breaker. It reflects whether it can operate safely and stably, especially the opening and closing speed, which is an important basis for judging the performance and stable operation of the circuit breaker, so these indicators need to be checked and repaired frequently. Since the vacuum circuit breaker above 10kV has a large mass and is not easy to be transported manually, a special maintenance handcart is usually used as an operating platform during inspection ...
