Technical field
The utility model system relates to the electric supply installation of joining of electric railway, relates in particular to the power transmission and transformation stations occasion of 27.5kV electric railway.
Background technology
At present, in China electric railway system, railway is joined the also fewer of cabinet, installation, use with vacuum circuit-breaker, and intelligent supplementary measures are not also very good.Therefore need the railway vacuum circuit-breaker that a kind of volume of design is little, multiple functional, reliability is high.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of 27.5kV railway vacuum circuit-breaker, and versatility is good, and is simple in structure, and connecting-disconnecting function is strong, and the life-span is long, and operating function is complete, is particularly useful for electric railway and cut-offs important load and frequent operation.
for solving the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of 27.5kV railway vacuum circuit-breaker, comprise the handcart that is formed by roller and handcart frame, be installed on the top of handcart frame with the high-pressure vacuum breaker of operating mechanism, handcart advancing mechanism is installed on the middle part of handcart frame, the interlock that is installed on handcart advancing mechanism top matches with handcart advancing mechanism and operating mechanism, upper conductive plate is arranged on the upper contact head seat of high-pressure vacuum breaker, lower conducting plate is arranged on the bottom of high-pressure vacuum breaker by zinc oxide arrester, insulating contact is arranged on the termination of conductive plate and lower conducting plate, travel switch and grounding contact are arranged on the bottom of handcart frame, offer hand crank on vacuum circuit breaker and advance the hole.
Zinc oxide arrester is fixedly mounted on the handcart frame.
High-pressure vacuum breaker and operating mechanism form integral structure.
Handcart advancing mechanism is the screw mandrel propulsive mechanism.
Vacuum circuit breaker is provided with observation window.
On the handcart frame, handle is installed.
The 27.5kV railway vacuum circuit-breaker that the utility model provides, beneficial effect is as follows:
1, utilize interlock between handcart advancing mechanism, operating mechanism to control high-pressure vacuum breaker when operation or correctly closing during the turnover high-tension switch cabinet, sub-switching operation; The design of insulating contact can be guaranteed after handcart enters switch cabinet body, the galvanic circle of high-pressure vacuum breaker and the connection of the galvanic circle of cabinet; The electric terminal of travel switch guarantees the secondary electrical connection of vacuum circuit-breaker handcart and switch cabinet body, and normally switching on and off when test position and service position; Grounding contact namely produces reliable ground connection electrical connection with cabinet after handcart enters cabinet, guarantee the circuit breaker reliable ground; The utility model versatility is good, and is simple in structure, and connecting-disconnecting function is strong,, the life-span is long, and operating function is complete, is particularly useful for electric railway and cut-offs important load and frequent operation.
2, volume is little, both can use separately, also can coordinate switch cubicle to use.
3, the handcart-type structure has facilitated test of the present utility model, maintenance and maintenance.
4, handcart advancing mechanism adopts the screw mandrel propulsive mechanism, and turnover steadily.
5, the stability of interlock energy Reliable guarantee circuit breaker handcart when meeting with an accidet, guarantee that railway reliably cut-offs, closes with vacuum circuit-breaker the short circuit current that closes the accident fault.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples:
Fig. 1 is structural representation of the present utility model;
Fig. 2 is end view of the present utility model.
Embodiment
as depicted in figs. 1 and 2, the utility model comprises the handcart that is comprised of roller 14 and handcart frame 1, be installed on the top of handcart frame 1 with the high-pressure vacuum breaker 4 of operating mechanism, handcart advancing mechanism 2 is installed on the middle part of handcart frame 1, the interlock 3 that is installed on handcart advancing mechanism 2 tops matches with handcart advancing mechanism 2 and operating mechanism and realizes interlocking, when namely making handcart advance (or shifting out) in switch cubicle with handcart advancing mechanism 2, high-pressure vacuum breaker 4 can not close, sub-switching operation, and only when handcart enters test position or service position, high-pressure vacuum breaker 4 just can close, sub-switching operation, simultaneously, when test position or service position are in "on" position, if will pass in and out handcart, interlock 3 will make high-pressure vacuum breaker 4 separating brake immediately when high-pressure vacuum breaker 4, and handcart could pass in and out in switch cubicle.
Upper conductive plate 5 is arranged on the upper contact head seat of high-pressure vacuum breaker 4, lower conducting plate 7 is arranged on the bottom of high-pressure vacuum breaker 4 by zinc oxide arrester 8, insulating contact 6 is arranged on the termination of conductive plate 5 and lower conducting plate 7, the effect of insulating contact 6 be in handcart enters switch cabinet after, the galvanic circle of high-pressure vacuum breaker 4 and the galvanic circle of switch cabinet are connected.
High-pressure vacuum breaker 4 and operating mechanism form integral structure.
Handcart advancing mechanism 2 is the screw mandrel propulsive mechanism.
Handle 12 is installed on handcart frame 1, the effect of handle 12 is to hold for operating personnel, promotes handcart mobile and promote handcart and enter into the test position of switch cabinet body or pull handcart to make handcart fall back on switch cabinet from the test position of switch cabinet body external switch cabinet outside.
Handcart frame 1 is basic mounting framework of the present utility model, totally 4 of handcart roller 14() be arranged on the both sides, bottom of handcart frame 1.
