In the invention, the integral lower contact is adopted, the current guide copper sheet is thickened, the current guide capability of the isolating switch is greatly increased, and the produce can be applied in a large-current line; and moreover, a belleville spring is adopted, and the Belleville spring not only reduces the occupation space but also is economic and has high safety and long service life under the premise of ensuring the fastening force.
Description
Technical field
The present invention relates to a kind of high-voltage electrical equipment, particularly a kind of outdoor AC high-voltage isolating switch.
Background technology
The outdoor AC high-voltage isolating switch of existing identical electric pressure is used for the overhead distribution system, the safe fracture that provides Maintenance and Repair to use.Because of visible cut-off point is arranged intuitively, and when cut-offfing instrument with deflection formula load and use, can play the effect of the little load current of disjunction, create safe operational environment for maintenance circuit and service equipment, be used widely.But in electric line, the ac high-voltage isolating switch that generally uses at present is because contact adopts split-type structural down; The water conservancy diversion copper coin is thiner; Secondly blade of knife switch, following contact, following terminal block are independent split type, and having formed many places divides breakpoint, cause contact to be prone to heating; Temperature rise too high useful life that has a strong impact on product, the shortcomings such as difficulty of product overall package have been increased simultaneously.Because the problem of temperature rise is difficult to be applied to than in the heavy current circuit.
Summary of the invention
The objective of the invention is in order to overcome the deficiency of prior art, provide that a kind of flow conductivity is strong, easily assembled, the outdoor AC high-voltage isolating switch of long service life.
The present invention realizes through following technical scheme:
A kind of outdoor AC high-voltage isolating switch comprises mounting seat and is located at moving contact seat and the static contact seat on the mounting seat that moving contact seat is provided with upper contact head and conductive prong; Static contact seat is provided with down contact; Be connected with blade of knife switch between said moving contact seat and the static contact seat, blade of knife switch one end embedding is sandwiched in upper contact head, which is provided with the operation draw ring; The other end is installed in down on the contact through screw is rotating, and said contact down is an integral structure.
As further improvement, contact is an integral type U type structure under the above.To descend contact thickness to increase, keep having saved time contact supporting on the intensity based.
As further improving, be crimped with disk spring between the above screw and the blade of knife switch.
The present invention can be applicable to the high pressure of 12kV.
Compared with prior art, the invention has the beneficial effects as follows:
(1) the following contact of integral structure, its water conservancy diversion copper sheet thickens, and has increased substantially the flow conductivity of isolating switch, and product can be applied to than in the heavy current circuit;
(2) the following contact of integral structure has reduced the branch breakpoint, makes temperature rise reduce, and has prolonged the useful life of product; And easy for installation, reduced the difficulty that switch is assembled, improved production efficiency.
(3) adopt disk spring to replace original helical spring, under the prerequisite that guarantees fastening force, not only reduced taking up room, make up easy to use, and economical, safe, long service life.

Embodiment
Below in conjunction with accompanying drawing the present invention is further specified, but protection scope of the present invention is not limited only to embodiment.
Embodiment:
Fig. 7 ~ Fig. 9 is the outdoor AC high-voltage isolating switch of prior art; Contact comprises contact supporting 13 and split type contact 14 down down under it, and the water conservancy diversion copper sheet of split type contact 14 down is thinner, and flow conductivity is lower; And the increase that divides breakpoint causes temperature rise to improve, and life of product shortens.
As improvement, like Fig. 1 ~ shown in Figure 6, a kind of outdoor AC high-voltage isolating switch; Comprise mounting seat 1 and be located at the moving contact seat 2 and static contact seat 12 on the mounting seat 1, moving contact seat 2 is provided with upper contact head 4 and conductive prong 5, and static contact seat 12 is provided with down contact 10; Be connected with blade of knife switch 7 between moving contact seat 2 and the static contact seat 12, blade of knife switch 7 one end embeddings are sandwiched in upper contact head 4, which is provided with operation draw ring 6; The other end is through screw 9 rotating being installed in down on the contact 10, and said contact 10 down is an integral structure.
Following contact 10 after the improvement saves down contact supporting 13, and its water conservancy diversion copper sheet thickens, and has increased substantially the flow conductivity of isolating switch, and product can be applied to than in the heavy current circuit; Reduce the branch breakpoint, made temperature rise reduce, prolonged the useful life of product; And easy for installation, reduced the difficulty that switch is assembled, improved production efficiency.
Crimp spring after the improvement adopts disk spring to replace original helical spring, under the prerequisite that guarantees fastening force, has not only reduced taking up room, make up easy to use, and economical, safe, long service life.
