Description

Outdoor AC high-voltage isolating switch

Technical field

The utility model relates to a kind of outdoor AC high-voltage isolating switch.

Background technology

Isolating switch is commonly called as " disconnecting link ", is in high-voltage switch electric appliance, to use maximum a kind of electrical equipment, plays buffer action in circuit.The principles and structure of itself is fairly simple, but because use amount is large, functional reliability requires high, and the impact of design, foundation and safe operation on electric substation, power plant is all larger.The main feature of disconnecting link is without arc extinguishing ability, can only in the situation that there is no load current, divide, close circuit.

In prior art, dividing, closing of outdoor AC high-voltage isolating switch, is by rotating knife brake lining, makes two side plates of switch contact or separate to realize with contact, between switch and contact, there is no special location structure, conventionally two side plate designs are and the incompatible realization of contact close-fitting location.Long-term use, two side plates and fixed contact very easily wear and tear, and cause loose contact, directly affect the validity of switch.

Therefore, the inventor, specially for problems of the prior art, develops a kind of outdoor AC high-voltage isolating switch, and this case produces thus.

Utility model content

The purpose of this utility model is to provide a kind of outdoor AC high-voltage isolating switch, makes it simple in structure, and contact is good, guarantees the validity of switch.

To achieve these goals, the technical solution of the utility model is as follows:

Outdoor AC high-voltage isolating switch, comprise base, moving contact, static contact and switch, moving contact and fixed contact are arranged on base, two side plates of switch one end and moving contact pivot joint, between two side plates of the switch other end, be provided with hook, handle and back-moving spring, hook is V-shape, the break place of V-shape is hubbed between two side plates, one end of V-shape also forms forward the hook that can catch on fixed contact base to downward-extension, the other end of V-shape extends back and forms driving section, handle is hubbed between two side plates, the lower end of handle extends to form forward operating portion, operating position is in the below of driving section, back-moving spring is arranged between hook and side plate, make driving section be pressed on operating portion and hook hooks forward by action of reset spring.

Described back-moving spring is torsion spring, and torsion spring set is on the pivot at hook break place, and one end of torsion spring is fixed on side plate, and the other end of torsion spring fixes on the hook of hook.

The outside of described hook forms lead angle.

On described handle, form draw ring.

Adopt after such scheme, the utility model is simple in structure, because increased hook, handle and back-moving spring between two side plates, when combined floodgate, the hook of hook hooks on the base of fixed contact, locking bit in realization, the ground switch of guaranteeing to close a floodgate contacts well with fixed contact, guarantees the validity of switch.

Below in conjunction with drawings and the specific embodiments, the utility model is described in further details.

Brief description of the drawings

Fig. 1 is decomposing schematic representation of the present utility model;

Fig. 2 is "on" position schematic diagram of the present utility model;

Fig. 3 is gate-dividing state schematic diagram of the present utility model.

Label declaration

Base 1, moving contact 2, static contact 3, base 31, switch 4, side plate 41, bolt 42, rivet 43, rivet 44, hook 5, hook 51, driving section 52, lead angle 53, handle 6, operating portion 61, draw ring 62, back-moving spring 7.

Embodiment

As shown in Figure 1 to Figure 3, be the outdoor AC high-voltage isolating switch that the utility model discloses, comprise base 1, moving contact 2, static contact 3 and switch 4.Moving contact 2 and fixed contact 3 are arranged on base 1.Two side plates 41 of switch 4 one end, by bolt 42 and moving contact 2 pivot joints, are provided with hook 5, handle 6 and back-moving spring 7 between two side plates 41 of switch 4 other ends.

Hook 5 is V-shape, and the break place of V-shape is hubbed between two side plates 41 by rivet 43.One end of V-shape is to downward-extension and form forward hook 51, and hook 51 can catch on fixed contact 3 bases 31 in good time.The other end of V-shape extends back and forms driving section 52.Close a floodgate for convenient, the outside of hook 51 forms lead angle 53.

Handle 6 is hubbed between two side plates 41 by rivet 44.The lower end of handle 6 extends to form forward operating portion 61, and operating portion 61 is positioned at the below of driving section 52.In order to facilitate separating brake, on handle 6, form draw ring 62.

Back-moving spring 7 is arranged between hook 5 and side plate 41, and back-moving spring 7 specifically can adopt torsion spring, and torsion spring set is upper at the pivot (rivet 43) at hook 5 break places, and one end of torsion spring is fixed on side plate 41, and the other end of torsion spring fixes on the hook 51 of hook 5.By the elastic reaction of back-moving spring 7, make to link up with 5 and clockwise rotate, driving section 52 is pressed on operating portion 61, and hook 51 hooks forward.

When the utility model closes a floodgate, switch 4 is turned downwards, while contact with fixed contact 3 to two side plates 41 of switch 4, realize and closing a floodgate, now, the hook 51 of hook 5 hooks on the base 31 of fixed contact 3, locking bit in realization, as shown in Figure 2, the ground switch 4 of guaranteeing to close a floodgate contacts well with fixed contact 3, guarantees the validity of switch.

When the utility model separating brake, upwards lift hand 6, make to shake hands 6 operating portion 61 upwards rotates, and the effect that drives the driving section 52 of hook 5 to overcome back-moving spring 7 is also upwards rotated, and the hook 51 of hook 5 is drawn back, hook 51 separates with the base 30 of fixed contact 3, realize release, continue switch 4 upwards to turn, when switch 4 is separated with fixed contact 3, realize separating brake, as shown in Figure 3.

These are only specific embodiment of the utility model, not the restriction to protection range of the present utility model.All equivalent variations of doing according to the mentality of designing of this case, all fall into the protection range of this case.
