Embodiment Construction
[0029] Such as Figure 1-3 The shown anti-seismic structure of a handcart circuit breaker includes a handcart guide rail assembly structure plate 5, the lower part of the handcart guide rail assembly structure plate 5 is bent and provided with a support plate 3, and a number of springs 2 are arranged on the support plate 3 at intervals. 2. It is evenly distributed between the handcart guide rail 1 and the support plate 3, and the two ends are fixed by notch limit or welding. Under normal conditions, the installed spring 2 is always in a compressed state, acting on the guide rail 1 of the handcart.
[0030] In order to improve the supporting performance, the spring 2 is made of carbon steel.
[0031] The upper end of the spring 2 is provided with a handcart guide rail 1 , the upper part of the handcart guide rail 1 is provided with a grounding guide rail 4 , and a guide wheel guide groove 51 is arranged between the handcart guide rail 1 and the grounding guide rail 4 .

The invention discloses an anti-seismic structure of a handcart circuit breaker. A supporting plate is arranged on the lower portion of a handcart guide rail assembling structural plate in a bent mode, a plurality of elastic supporting structures are arranged on the supporting plate at intervals, a handcart guide rail is arranged at the upper ends of the elastic supporting structures, and a grounding guide rail is arranged on the upper portions of the handcart guide rail; a guide wheel guide groove is arranged between the handcart guide rail and the grounding guide rail; the handcart guide rail assembly structural plate is provided with a handcart breaker guide end; the handcart circuit breaker and the handcart circuit breaker anti-seismic structure are installed along the handcart circuit breaker guide end, handcart chassis guide wheels on the two sides of a handcart chassis of the handcart circuit breaker slide along the guide wheel guide grooves, and after the stress balance is achieved through the elastic force of the elastic supporting structure and the gravity of the handcart circuit breaker, the contact of the handcart circuit breaker is contacted with or separated from the contact seat. The acting force and the counter-acting force are attenuated and counteracted through effective combination, so the anti-seismic performance of equipment is improved.
Description
technical field [0001] The invention relates to the field of industrial electrical equipment, in particular to an anti-seismic structure of a handcart circuit breaker. Background technique [0002] At present, in the application process of the handcart circuit breaker, the material of the guide rail is mostly changed to improve the anti-seismic effect, and the matching connection between the plum blossom contact of the handcart circuit breaker and the closing contact seat is used for reinforcement. Usually, during the anti-seismic test or the use of the product, the handcart circuit breaker is in the working position, and the anti-seismic capability of the test position is basically not considered or tested. [0003] In the actual transportation process, the conventional method is to transport the handcart circuit breaker and the switch cabinet separately, so as to ensure that the guide rail will not be deformed due to the vibration and turbulence of the vehicle transportati...
