Abstract
The utility model relates to an electrical switch and provides a solid seal vacuum switch which has compact structure, small size and good sealing property. The solid seal vacuum switch comprises a box body and a circuit breaker, a fuse and an isolating switch arranged in the box body, wherein a support rod is arranged on the inner side wall of the box body; a contact is arranged on the support rod; a vacuum arc extinguish chamber is arranged on the circuit breaker; the isolating switch is arranged above the box bod; the circuit breaker is arranged in the middle of the box body; the fuse is arranged below the box body; the vacuum arc extinguish chamber is arranged below the isolating switch; a static contact of the isolating switch is integrated with a post of the vacuum arc extinguish chamber; and a moving contact of the isolating switch is conducted with a contact of the support rod in the box body and matched with the circuit breaker.
Description
Technical field
The utility model relates to a kind of electric switch, particularly a kind of vacuum switch that seals admittedly.
Background technology
On-load switch is a kind of device for switching between circuit breaker and isolating switch, has simple arc-control device, can cut off rated load electric current and certain overload current, but can not cutting-off of short-circuit electric current; It can be divided into high voltage load switch and low-voltage load switch according to working voltage.High voltage load switch mainly contains 6 kinds: solid air-generating high voltage load switch, air pressing type high voltage load switch, compressed air type high voltage load switch, SF6 formula high voltage load switch, oil-immersed and high-voltage on-load switch and vacuum type high voltage load switch.Wherein the vacuum type high voltage load switch is to utilize vacuum medium arc extinguishing, and electric life is long, and relative price is higher, is applicable to 220 kilovolts and following product.Present vacuum type high voltage load switch has isolating switch and vacuum interrupter usually; After the main effect of isolating switch is separating brake; Set up reliable clearance for insulation, the equipment or the circuit of needs maintenance separated with an obvious cut-off point with power supply, with the safety of assurance maintainer and equipment; Vacuum interrupter has another name called vacuum switch tube, is the core component of mesohigh power switch, and it mainly acts on and is, makes behind the mesohigh circuitry cuts power supply blow-out rapidly and suppresses electric current through the good insulating properties of vacuum in managing, and avoids accident to take place with unexpected.But isolating switch is distinguished with the vacuum interrupter on the circuit breaker and is connected separately in the present vacuum type high voltage load switch, makes that whole vacuum type high voltage load switch overall structure is big, installs and uses to take up room too greatly, makes its range of application that certain limitation arranged.Volume is too big, when switch is installed in the open air for a long time, under Effect of Environmental, must make this switch produce situation such as corrosion, electric leakage, influences the useful life of switch.
The utility model content
Therefore, to above-mentioned problem, the utility model proposes a kind of compact conformation, volume is little, closure is good solid envelope vacuum switch.
For solving this technical problem, the utility model is taked following scheme: a kind of vacuum switch that seals admittedly comprises casing and is located at circuit breaker, fuse and the isolating switch in the casing; Said box inside wall is provided with support bar, and this support bar is provided with contact, and said circuit breaker is provided with vacuum interrupter; Said isolating switch is arranged on the casing top; Said circuit breaker is located at the casing middle part, and said fuse is located at the casing below, and said vacuum interrupter is arranged on the isolating switch below; The fixed contact of said isolating switch and the pole of vacuum interrupter are wholely set, and the contact conducting of the moving contact of said isolating switch and casing inner bracing piece and opening circuit cooperates.
Through adopting the aforementioned techniques scheme, the beneficial effect of the utility model is: the vacuum interrupter on isolating switch and the circuit breaker is wholely set, and makes the whole vacuum switch structure compactness of sealing admittedly, and volume is little; The whole casing that seals vacuum switch admittedly adopts the poured with epoxy resin moulding, make the utility model product hermeticity good, but anti-corrosion is avoided the appearance of leaky.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment.
Embodiment
Combine accompanying drawing and embodiment that the utility model is further specified at present.
With reference to figure 1; A kind of vacuum switch that seals admittedly of preferred the utility model comprises casing 1 and is located at circuit breaker 2, fuse 3 and the isolating switch 4 in the casing 1 that said casing 1 madial wall is provided with support bar 11; This support bar 11 is provided with contact; Said circuit breaker 2 is provided with vacuum interrupter 21, and said isolating switch 4 is arranged on casing 1 top, and said circuit breaker 2 is located at casing 1 middle part; Said fuse 3 is located at casing 1 below; Said vacuum interrupter 21 is arranged on isolating switch 4 belows, and the fixed contact of said isolating switch 4 41 is wholely set with the pole 211 of vacuum interrupter 21, and the contact conducting of the moving contact 42 of said isolating switch 4 and casing 1 inner bracing piece 11 and opening circuit cooperates.
The utility model at first is connected setting through isolating switch with vacuum interrupter one on the circuit breaker, makes whole vacuum load switch compact conformation, and volume is little; The casing of whole vacuum load switch adopts the poured with epoxy resin moulding, make the utility model product hermeticity good, but anti-corrosion is avoided the appearance of leaky.
Although specifically show and introduced the utility model in conjunction with preferred embodiment; But the those skilled in the art should be understood that; In the spirit and scope of the utility model that does not break away from appended claims and limited; Can make various variations to the utility model in form with on the details, be the protection range of the utility model.
Claims (1)
1. one kind is sealed vacuum switch admittedly, comprises casing and is located at circuit breaker, fuse and the isolating switch in the casing, and it is characterized in that: said box inside wall is provided with support bar; This support bar is provided with contact; Said circuit breaker is provided with vacuum interrupter, and said isolating switch is arranged on the casing top, and said circuit breaker is located at the casing middle part; Said fuse is located at the casing below; Said vacuum interrupter is arranged on isolating switch below, and the fixed contact of said isolating switch and the pole of vacuum interrupter are wholely set, and the contact conducting of the moving contact of said isolating switch and casing inner bracing piece and opening circuit cooperates.
