Abstract
The utility model provides an indoor high-voltage vacuum circuit breaker with insulating supports, which is provided with an L-shaped frame, wherein the upper part of an insulating cylinder is fixed with the side wall of the frame into a whole, and the insulating supports are arranged between the frame and the lower end surface of the insulating cylinder. By additionally arranging the insulating supports with different height between the frame and the lower end surface of the insulating cylinder, not only air distance of a breaker electrode (lower outgoing line) over the ground is increased and insulating performance of products is enhanced, but also current-carrying capacity of the indoor high-voltage vacuum circuit breaker is improved and safety and reliability of the products in running are guaranteed simultaneously. Moreover, the insulating supports have different specifications, so as to satisfy different needs of users, and be convenient to adjust and organize production simultaneously; in addition, the indoor high-voltage vacuum circuit breaker has high performance-price ratio due to low cost.
Description
Technical field
The utility model relates to the indoor high-voltage vacuum circuit breaker that a kind of tape insulation supports, and satisfies the user demand of user for product different insulative level.
Background technology
In the indoor electrical power trans mission/distribution system of 12kV; indoor high-voltage vacuum circuit breaker uses very extensive, almost accounts for more than 98% of circuit breaker use amount, simultaneously because electrical network need; the user according to height above sea level or actual service conditions, requires to improve the insulation property of product through regular meeting.Use the demand that dual mode satisfies the user at present both at home and abroad always: the one, the circuit breaker insulation system does not adjust, satisfy user's needs by the original design insulation margin of circuit breaker, and the design of product insulation margin generally is not very big, doing so on the one hand is restricted the product scope of application, also stayed accident potential on the other hand, easily because the insulation deficiency causes the electrical network paralysis; The 2nd, exploitation corresponding insulation part (insulating cylinder) mfg. moulding die is adjusted original circuit breaker insulation system, improves the insulation level of circuit breaker.User's demand is always changing, single structure is not good selection, so just need exploitation multiple kinds of molds (insulating cylinder), change the structure of product, satisfy the needs of different user, so just cause disposable input too big, improved the cost of product, also prolonged the manufacturing cycle of product simultaneously.
The utility model content
The technical problem that the utility model solves: the indoor high-voltage vacuum circuit breaker that provides a kind of tape insulation to support, support by the insulation that increases differing heights, adjust the air gap over the ground of electrode, improved the insulation level of circuit breaker, satisfy user's different needs.
The technical solution adopted in the utility model: the indoor high-voltage vacuum circuit breaker that tape insulation supports, have L type framework, the top and the frame side wall of insulating cylinder are fixed as one, and are provided with insulation between described framework and the insulating cylinder lower surface and support.
Described insulation is supported for the sleeve shape body with sufficient mechanical strength and dielectric strength, the bottom surface end face of described insulating cylinder is provided with four screwed holes, the base of frame upper surface is provided with four and screwed hole 5 corresponding unthreaded holes, screw passes unthreaded hole from described framework inside and with screwed hole framework is connected with insulating cylinder, and described insulation support set is contained on the described screw.
The utility model advantage compared with prior art:
1, increases indoor high-voltage vacuum circuit breaker electrode air distance over the ground by installing the insulation support additional, improved insulation property;
2, the height of insulation support can be adjusted as required, and the product agent structure remains unchanged, and is convenient to tissue production, has improved efficient;
3, install insulation additional and support after, have the gap between insulating cylinder and the framework, be beneficial to cross-ventilation, good heat dissipation effect has correspondingly improved the current capacity of indoor high-voltage vacuum circuit breaker;
4, relative insulating cylinder mfg. moulding die greatly reduces the production cost.

Embodiment
Below in conjunction with accompanying drawing 1,2,3 a kind of embodiment of the present utility model is described.
The indoor high-voltage vacuum circuit breaker that tape insulation supports, has L type framework 1, the top of insulating cylinder 4 and framework 1 sidewall are fixed as one, it is characterized in that: be provided with insulation between described framework 1 and insulating cylinder 4 lower surfaces and support 3, it is the sleeve shape body with sufficient mechanical strength and dielectric strength that insulation supports 3, the bottom surface end face of insulating cylinder 4 is provided with four screwed holes 5, upper surface, framework 1 bottom is provided with four and screwed hole 5 corresponding unthreaded holes 2, screw 6 passes unthreaded hole 2 from described framework 1 inside and with screwed hole 5 framework 2 is connected with insulating cylinder 4, insulation is supported 3 and is sleeved on the screw 6, the effect of mechanical support is not only played in insulation support 3, and corresponding breaker electrode (following outlet) the air distance over the ground that increased, improved the insulation level of product, simultaneously owing to have the gap between insulating cylinder 4 and the framework 1, be beneficial to cross-ventilation, good heat dissipation effect has correspondingly improved the current capacity of indoor high-voltage vacuum circuit breaker.The height of insulation support 3 has multiple, and the insulation support 3 of differing heights can be satisfied the demand of different high user above sea level.Support 3 by increasing different insulation, both improved the different insulation level of circuit breaker, product is in operation and is more conducive to ventilate, dispel the heat simultaneously, has increased current capacity.The product overall target more is tending towards optimizing rationally, and with low cost, is easy to tissue production.
Install the indoor high-voltage vacuum circuit breaker after insulation is supported additional, insulation and current-carrying parameter are as follows:
Annotate: Ir is a rated current.
In sum, after the 12kV indoor high-voltage vacuum circuit breaker installs the insulation support additional, both increased breaker electrode (following outlet) air distance over the ground, the insulation property of product have been improved, improve the current capacity of indoor high-voltage vacuum circuit breaker simultaneously, guaranteed safety, the reliability of product when operation.Insulation supports 3 different size, has both satisfied user's different needs, is easy to simultaneously adjust, and is convenient to tissue production.Because it is with low cost, has very high cost performance, has created good economic benefit.
