Abstract
An all insulated all-sealed compact outdoor vacuum circuit breaker relates to the technical field of protection and control in power distribution systems of substations and industrial mining enterprises. The outdoor vacuum circuit breaker comprises one-piece terminal poles, wherein an upper wire seat is sealed and connected with an upper end of each terminal pole, and an incoming cable clamp is arranged in the upper wire seat; a lower wire seat is sealed and connected at one side of each terminal pole, and an outgoing cable clamp is arranged in the lower wire seat; a inner cavity of each terminal pole is provided with a vacuum arc extinguish chamber; and an upper end of each vacuum arc extinguish chamber is connected with an inner end of the incoming cable clamp. According to the outdoor vacuum circuit breaker, two segments of a conventional circuit breaker is combined into one segment; and upper wire seats and lower wire seats are all sealed inside the terminal poles; external cables can be directly inserted into the terminal poles, so that no primary conductive portions are exposed outside the terminal poles. As a result, insulation performance of the outdoor vacuum circuit breaker is substantially improved.
Description
Technical field
The utility model relates to protection and control technology field in transformer station and the industrial and mining enterprises' distribution system.
Background technology
Existing 10kV outdoor AC high-voltage vacuum circuit breaker will be used for power distribution network and cut-off, closes the load current, overload current and the short circuit current that close electric power system.Principal organ's characteristics:
1, the version of existing outdoor vacuum circuit breaker body is casing three-phase column support type, mainly is comprised of six parts such as conduction arc quenching system, insulation system, drive system, operating mechanism, housings.Because mechanism's parts are various, failure rate is higher;
2, pole is divided into two sections, and mid portion is gapped, and pole inside easily makes moist;
3, vacuum interrupter is placed in the pole, and vacuum interrupter and pole inwall have the air gap, easily produce flashover;
4, according to user's request 200/5～600/5 current transformer can be installed, lower outlet and pole link position are gapped, are placed on for a long time outdoor rainwater and infiltrate wherein decreasing insulating.
Summary of the invention
The utility model purpose is to design the outdoor AC high-voltage vacuum circuit breaker that a kind of all insulation that can improve moisture effect is sealed entirely admittedly.
The utility model comprises the pole of disjunctor, the seat of reaching the standard grade is tightly connected in the upper end of described pole, in the seat of reaching the standard grade, arrange the inlet wire cable clip, side seal at pole connects the seat that rolls off the production line, in the seat that rolls off the production line, arrange the outlet cable clip, at described pole inner chamber vacuum interrupter is set, the upper end of described vacuum interrupter links to each other with the inner of described inlet wire cable clip.
Ruuning situation from ZW32, outdoor products subject matter is exactly Rainproof moisture-proof, original pole form is that two joint docking form up and down, the utility model not only becomes a joint with two joints, and wire outlet seat all is enclosed in pole inside admittedly up and down, external cable can directly be inserted into the pole the inside, does not have exposed primary conductive part thereby reach the pole outside, and insulation property improve greatly.
The utility model also can directly be poured into vacuum interrupter in the pole, can further improve insulation property, truly reaches all insulation and entirely consolidates seal structure.
The utility model is because above design, can make original three the single-phase poles of product change the whole pole of three-phase integratedization into, thereby spaced apart reduces, the volume of bottom mechanism case also can further dwindle, insulation property improve, have the characteristics such as parts are few, power consumption is low, simple to operate, further prolonged the service life of outdoor breaker.
Description of drawings
Fig. 1 is a kind of structural representation of utility model.
Fig. 2 is that the A-A of Fig. 1 is to cut-away view.
Embodiment
As shown in Figure 1, 2, the utility model comprises the pole 1 of the disjunctor of three-phase integrated setting, and the seat 2 of reaching the standard grade that is tightly connected in the upper end of pole 1 is in the seat 2 interior layout inlet wire cable clips 3 of reaching the standard grade, side seal at pole 1 connects the seat 4 that rolls off the production line, in the seat 4 interior layout outlet cable clips 5 that roll off the production line.
At pole 1 inner chamber vacuum interrupter 6 is set, the upper end of vacuum interrupter 6 links to each other with the inner (being the lower end) of inlet wire cable clip 3.
7,8 are respectively into and out of the line cable among the figure.
Claims (1)
1. all insulation is sealed the compact outdoor vacuum circuit breaker entirely admittedly, it is characterized in that comprising the pole of disjunctor, the seat of reaching the standard grade is tightly connected in the upper end of described pole, in the seat of reaching the standard grade, arrange the inlet wire cable clip, side seal at pole connects the seat that rolls off the production line, arrange the outlet cable clip in the seat that rolls off the production line, at described pole inner chamber vacuum interrupter is set, the upper end of described vacuum interrupter links to each other with the inner of described inlet wire cable clip.
