Description
Technical field
The utility model relates to a utmost point or multipolar low-voltage circuit breaker, is specifically related to a kind of modularization low-voltage circuit breaker with quick tripping function.
Background technology
Existing low-voltage circuit breaker comprises the housing of being made up of base, base and cover, one utmost point or multipole contact device, operating mechanism are installed and are used to transship or the electromagnetic tripping apparatus of short circuit action in enclosure interior.When circuit breaker was subjected to big current overload, the effect that the contact head in the contact apparatus is subjected to electrodynamic repulsion force made the circuit breaker disjunction, reaches the effect of protection circuit and equipment.The every of multipolar low-voltage circuit breaker might be subjected to the impact of short circuit current in extremely, so require every utmost point can both reach the effect of current limliting and the quick disjunction of electromagnetism.
Contact head phase repulsive interaction current limliting and the action of the electromagnet portion in the electromagnetic tripping apparatus that low-voltage circuit breaker is abutted against in the system of touching realize disjunction.Because the low-voltage circuit breaker internal structure is very compact, does not have enough spaces, so existing low-voltage circuit breaker electromagnetic tripping apparatus often can not transmit signal fast between each module, also promptly generally can only be used for three-pole breaker.At present, adopt low-voltage circuit breaker to be implemented in the quick short-circuit signal that transmits between each module by the mode that airflow hole (or airslide) transmits air-flow, be used to transmit each mutually between the swingle and the airflow hole (or airslide) of short-circuit signal all be arranged in the housing, the defective of this structure is:
1, identical device need all be set in the both sides of each phase of low-voltage circuit breaker and act on mechanism respectively and just can transmit the short circuit current signal, complex structure and transmit unreliable.
2, operate time long, the short circuit breaking protective capability of low-voltage circuit breaker is reached capacity, be difficult to improve the disjunction class.
Summary of the invention
The purpose of this utility model is that existing low-voltage circuit breaker disjunction protective capability is easily saturated, the disjunction class is difficult to improve and the insecure problem of disjunction provides a kind of low-voltage circuit breaker with quick tripping function in order to solve; can reduce break-time, improve breaking capacity.
The utility model adopts technical scheme to be: respectively be fixed with the housing that is involuted by upper and lower covers in each both sides, utmost point contact, between the housing upper and lower covers, have two not connected airslides up and down, respectively establishing one in two airslides can be along the piston of corresponding air flow groove slip, near the other rod like parts that one one end is set near piston of the housing of contact one side of low-voltage circuit breaker operating mechanism, the other end of rod like parts is positioned at by the operating mechanism; Swingle one end is fixed on the rod like parts, and rod like parts one end of the swingle other end and contact opposite side is fixed, and the rod like parts other end is near the homonymy piston.
The beneficial effects of the utility model are:
When 1, the air-flow in the airslide promotes piston, piston slap rod like parts one end, the swingle that drive is fixed on it rotates, the other end of rod like parts drives the circuit breaker relieving mechanism simultaneously, because this relieving mechanism action is from last operate time early than the electromagnetic tripping apparatus the prior art electromagnetic system of time, thereby reduced an electromagnetic force is hit tripgear by adjusting rod link, so can make low-voltage circuit breaker disjunction early, reduce break-time, multipolar low-voltage circuit breaker breaking capacity is improved greatly, be used for the multipole of low-voltage circuit breaker and protect mutually; Realize the interchangeability of each phase module.
2, the utility model only needs a rod like parts just short-circuit signal can be delivered to each utmost point contact, simple in structure and reliable in action.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Fig. 1 is the utility model structural front view, the structure chart when wherein housing 100 is opened for loam cake.
Fig. 2 be among Fig. 1 A-A to cutaway view.
Among the figure: 100. housings; 101. airslide; 102. airslide; 103. piston; 104 pistons; 105. through hole; 106. through hole; 200. rod like parts; 201. spiral arm; 202. spiral arm; 203. rod like parts; 300. swingle; 400. contact; 401. pilot hole; 500. axle sleeve.
Embodiment
Shown in Fig. 1-2, each fixes one in each 400 both sides, utmost point contact the housing 100 that is involuted by upper and lower covers, be provided with two not connected airslides 101,102 between housing 100 upper and lower covers, these two airslides 101,102 are communicated with adjacent two-phase by the through hole 105,106 that is positioned at loam cake and covers down respectively.In two airslides 101,102 piston 103,104 is set respectively, piston 103,104 can slide along its corresponding airslide.
