Abstract
The utility model discloses a pole-type permanent magnet vacuum circuit breaker with good tightness, simple transmission structure and low fault rate. The pole-type permanent magnet vacuum circuit breaker comprises a case (8) and three fixedly sealed poles (2) arranged at the top part of the case (8). A permanent magnet mechanism (9) is arranged in the case (8) corresponding to lower parts of the fixedly sealed poles (2). The peripheries of the fixedly sealed poles (2) are fixedly sealed by epoxy resin integrally. The internal part is provided with an input terminal (1), an output terminal (3), a vacuum arc extinguish chamber (5) and an insulating tension rod (7) which is connected with the permanent magnet mechanism (9). The other end of the insulating tension rod (7) is connected with a movable contact in the vacuum arc extinguish chamber (5). The output terminal (3) and the vacuum arc extinguish chamber (5) are connected by a flexible lead (6). The utility model is widely applied to existing 12kV electric power system.
Description
Technical field
The utility model relates to a kind of pole type permanent magnetism vacuum circuit-breaker.
Background technology
Along with improving constantly of development and national economy, progress of science and technology and the people's material and cultural life level, society is also increasing to power demand, simultaneously the power system power supply quality is had higher requirement.Circuit breaker is as the terminal equipment of protecting electrical power system and control, and its reliability will produce far-reaching influence to the stability of electric power system.
Present high-tension vacuum switch equipment has many sealings not so good; The environment tolerance is poor, mostly adopts traditional spring operating mechanism, because the spring operating mechanism amount of parts is many; The wearing and tearing of mechanical part are big; Drive connection is complicated, and failure rate is higher, can not satisfy the reliability requirement of power supply and distribution of electric power system.
The utility model content
The utility model technical problem to be solved is the deficiency that overcomes prior art, and a kind of good airproof performance, drive mechanism is simple, failure rate is low pole type permanent magnetism vacuum circuit-breaker are provided.
The technical scheme that the utility model adopted is: the related pole type permanent magnetism vacuum circuit-breaker of the utility model comprises cabinet and three poles that are arranged on said cabinet top; The cabinet inside of correspondence position is provided with permanent magnet mechanism below said pole; It is one that said pole periphery is sealed by epoxy resin admittedly; The insulated tension pole that set inside has input terminal, outlet terminal, vacuum interrupter and is connected with permanent magnet mechanism; The other end of said insulated tension pole is connected in the indoor moving contact of said vacuum extinction, is connected by flexible conductor between said outlet terminal and the vacuum interrupter.
Further, the position that on said pole, is positioned at outlet terminal is provided with current transformer, and said current transformer is by epoxy sealing.
Further, also be provided with the manual switching-off device that links with said permanent magnet mechanism at said cabinet inside.
The beneficial effect of the utility model is: because the utility model adopts the permanent magnet mechanism of three independent operations; Directly the transmission insulated tension pole is controlled the break-make in the arc control device; This motion of mechanism parts and transmission link amount of parts in present all operating mechanisms is minimum; Mechanism's volume is minimum, and can realize the complete rectilinear motion of switchgear, therefore can the wearing and tearing and the power consumption of mechanical part be reduced to minimum; It has almost completely eliminated the possibility that produces mechanical breakdown, can satisfy the switch reliability requirement fully.In addition owing to seal admittedly at the periphery of input terminal, outlet terminal, vacuum interrupter and the insulated tension pole that is connected with permanent magnet mechanism employing epoxy resin integral, and cabinet also is all-sealed structure, so just guaranteed the overall sealing performance of circuit breaker.
Description of drawings
Fig. 1 is the utility model integral outer sketch map;
Fig. 2 is a single pole internal structure sketch map in the utility model.
Embodiment
Like Fig. 1, shown in Figure 2; The pole type permanent magnetism vacuum circuit-breaker of the utility model is mainly used in the 12KV electric power system, includes input terminal 1, pole 2, outlet terminal 3, current transformer 4, vacuum interrupter 5, flexible conductor 6, insulated tension pole 7, cabinet 8, permanent magnet mechanism 9 and manual switching-off device 10.Comparing main feature with existing product is: it comprise three independently 2, three poles 2 of pole be fixed on the top of said cabinet 8, pole 2 comprises input terminal 1, outlet terminal 3, current transformer 4, vacuum interrupter 5 and insulated tension pole 7 etc.; Its entire periphery employing epoxy resin APG technology is sealed admittedly and is one; Epoxy resin is again the main mechanical support part of product both as the main insulation of product, has both satisfied the insulation property and the mechanical performance requirement of product; Shortened the electric conductor length of major loop again greatly; Electric conductivity is good, makes that simultaneously this product overall structure is compact, and outlet terminal 3 is conducted electricity by flexible conductor 6 with vacuum interrupter 5 and is connected; Three independently permanent magnet mechanism 9 be fixed on the inside of said cabinet 8; Insulated tension pole 7 is positioned at the inside of pole 2, and it passes cabinet 8 vacuum interrupter 5 is connected with permanent magnet mechanism 9, forms the break-make that moving contacts in the vacuum interrupter 5 are controlled in the straight line transmission; Manual switching-off device 10 is positioned at below the permanent magnet mechanism 9, can link with permanent magnet mechanism 9.
The operation principle of the utility model is following: adopt three independently permanent magnet mechanism 9 linear drives insulated tension poles 7 accomplish the branch closing operation of moving contacts in the vacuum interrupter 5; Closing position is tried hard to keep by permanent magnetism and is held; The separating brake position leans on spring force to keep (not shown); Abandon complicated mechanical transmission mechanism in the existing product, reduced hazard rate, improved operating reliability; In this external cabinet manual switching-off device 10 is housed also, and with three permanent magnet mechanisms 9 interlock, in case of emergency also can realize the three manual emergency separating brakes that link through manual switching-off device 10.
