Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of circuit breaker production, in particular to a high-voltage circuit breaker assembling, testing and packaging production line. BACKGROUND

[0002] A high-voltage circuit breaker is a switching device that can close, carry and break the current under normal circuit conditions, and can close, carry and break the current under abnormal circuit conditions (such as short circuit) within a specified time. The types of high-voltage circuit breakers mainly include post-type circuit breakers and common-tank circuit breakers.

[0003] Generally, the structure of a high-voltage circuit breaker includes: a moving contact and a stationary contact, which are in contact when the circuit breaker is closed, and the circuit is turned on; when the circuit breaker is opened, the moving contact and the stationary contact are separated, and the circuit is turned off; a conducting rod for connecting the contacts and the external circuit to ensure that the current can pass smoothly; an arc extinguishing device for quickly extinguishing the arc to prevent damage to the contacts and equipment, and to avoid the continuous burning of the arc causing a short circuit failure; insulation components for ensuring sufficient insulation strength between the conducting parts of the circuit breaker and the ground, and between the phases, to prevent electric shock and short circuit; an operating mechanism for driving the opening and closing actions of the circuit breaker; a transmission system for transmitting the power of the operating mechanism to the conducting parts of the circuit breaker to realize the opening and closing actions; and support components for supporting the various parts of the circuit breaker.

[0004] At the production site, workers assemble the components of the high-voltage circuit breaker, such as the moving contact, the stationary contact, the conducting rod, the arc extinguishing device, the insulation components, the operating mechanism, the transmission system, and the support components, into a box to obtain a finished high-voltage circuit breaker according to the assembly process. The box is transported to each assembly process location by a traditional trolley, but the traditional trolley lacks a guiding function. When multiple trolleys move from one assembly process location to the next, they are prone to collide and deviate from the moving direction, and the placement of multiple trolleys is messy and crowded, which can easily occupy the production line's worker walking path and other material transportation paths, which is not conducive to the production efficiency of the high-voltage circuit breaker.

[0005] After assembling the high-voltage circuit breaker, it also needs to be tested, such as mechanical property testing, long-term heating testing, power frequency voltage withstand testing, short-circuit breaking and closing ability testing, and special environment adaptation testing. The tested high-voltage circuit breaker is transported to the packaging area by a trolley, such as packaging the high-voltage circuit breaker in a wooden box and fixing it on the wooden box bottom plate with screws. After completing the packaging, it is sold to the market. Since the high-voltage circuit breaker is generally heavy, manually moving the assembled high-voltage circuit breaker from the trolley to the testing equipment and manually moving the tested high-voltage circuit breaker from the trolley to the wooden box for packaging is labor-intensive and inefficient.
