Abstract
The utility model discloses an isolating switch, which comprises a revolution plate, an insulating ceramic member, a wire outgoing seat, an intermediate contact, a contact, a linking rod, a bearing pedestal, an underframe and a joint. The isolating switch is characterized in that the contact is provided with a rainproof cover, an n-shaped outer frame and a pressing plate. The n-shaped outer frame is provided with the rainproof cover and is sleeved onto the pressing plate and the contact. The n-shaped outer frame is in threaded connection with the rainproof cover. The pressing plate is provided with a circular groove matched with the bottom of the rainproof cover. One side of the contact, positioned close to the pressing plate, is provided with a concave hole. The pressing plate is provided with a convex block matched with the concave hole. According to the technical scheme of the utility model, due to the adoption of the isolating switch, the direct contact between a bolt and a contact is prevented. In this way, the problem that the clamping force of the contact is decreased due to the bolt corrosion and thermal annealing phenomena in the prior art can be avoided. Due to the arrangement of the circular groove on the pressing plate, the positioning effect is realized. Due to the arrangement of the convex block on the pressing plate, the longitudinal sliding phenomenon of the isolating switch due to the insufficient clamping force of the contact can be avoided.
Description
Technical field
The utility model belongs to high voltage power transmission field, and more particularly, it relates to a kind of high voltage isolator of electric power system.
Background technology
High voltage isolator is in electric power system, to be used for deciliter having voltage and the switch of zero load circuit is the power equipment of consumption maximum in electric power system, and major part is used out of doors.Contact, as the vitals of isolating switch, often exists contact burn, corrosion, wearing and tearing to make loose contact; Contact fingertip in service, spring corrosion, overheated, elastic force reduces, holddown spring or screw lax, the edge of a knife closes not tight; Contact fingertip surface oxidation, contact resistance increases.
Utility model content
The deficiency existing for prior art, the purpose of this utility model is to provide a kind of contact a kind of isolating switch in useful life that improves.
For achieving the above object, the utility model provides following technical scheme: a kind of isolating switch, comprise finger plate, insulating porcelain piece, wire outlet seat, middle contact, contact, link rod, bearing pedestal, underframe and joint, it is characterized in that: described contact is provided with Contraband word housing and pressing plate, on described contact, comprise rain-proof cover, Contraband word housing and pressing plate, described Contraband word housing is provided with rain-proof cover, described Contraband word outer frame set is located on pressing plate and contact, described Contraband word housing is threaded with rain-proof cover, described pressing plate is provided with the circular groove matching with rain-proof cover bottom, described contact is provided with shrinkage pool near pressing plate one side, described pressing plate is provided with the projection matching with shrinkage pool.
By adopting technique scheme, between bolt and contact, directly do not contact, avoided the contact clamping force causing because of bolt corrosion, heating annealing at present to reduce, the design of circular groove on pressing plate, played positioning action, the design of pressing plate projection, the longitudinal sliding motion that has stoped contact to cause not because of clamping force.
Described close two contact end places are provided with two shrinkage pools, match with two projections of one side under pressing plate.
By adopting technique scheme, increase the fastness of contact and pressing plate, improved contact reliability.
Described rain-proof cover top is umbrella, and bottom is cylindrical thread shape.
By adopting technique scheme, and simple in structure, easy accessibility.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of isolating switch of the utility model embodiment;
Fig. 2 is a kind of isolating switch A-A of the utility model embodiment cutaway view.
In figure: contact, 5-contact, 6-link rod, 7-bearing pedestal, 8-underframe, 9-joint, 10-rain-proof cover, 11-pressing plate, 12-Contraband word housing, 13-circular groove, 14-contact shrinkage pool, 15-projection in the middle of 1-finger plate, 2-insulating porcelain piece, 3-wire outlet seat, 4-.
Embodiment
With reference to attached Fig. 1 and 2 specific embodiment, the utility model is described further.
A kind of isolating switch, comprise finger plate 1, insulating porcelain piece 2, wire outlet seat 3, middle contact 4, contact 5, link rod 6, bearing pedestal 7, underframe 8 and joint 9, described contact 5 is provided with Contraband word housing 12 and pressing plate 11, on described Contraband word housing 12, there is rain-proof cover 10, on described contact 5, comprise rain-proof cover 10, Contraband word housing 12 and pressing plate 11, described Contraband word housing 12 is provided with rain-proof cover 10, described Contraband word housing 12 is set on pressing plate 11 and contact 5, described Contraband word housing 12 is threaded with rain-proof cover 10, described pressing plate 11 is provided with the circular groove 13 matching with rain-proof cover 10 bottoms, described contact 5 is provided with shrinkage pool 14 near pressing plate one side, described pressing plate is provided with the projection 15 matching with shrinkage pool 14.
Cross employing technique scheme, between bolt and contact 5, directly do not contact, avoided contact 5 clamping forces that cause because of bolt corrosion, heating annealing at present to reduce, the design of circular groove 13 on pressing plate 11, played positioning action, the design of pressing plate projection 15, the longitudinal sliding motion that has stoped contact 5 to cause not because of clamping force.
Described close two contact 5 ends are provided with two shrinkage pools 14, match with two projections 15 of 11 times one sides of pressing plate.
By adopting technique scheme, increase the fastness of contact 5 and pressing plate 11, improved contact reliability.
Described rain-proof cover 10 tops are umbrella, and bottom is cylindrical thread shape.
By adopting technique scheme, and simple in structure, easy accessibility.
The foregoing is only preferred embodiment of the present utility model, not in order to limit the utility model, those skilled in the art carries out common variation and replaces should being included within the scope of technical solutions of the utility model.
