Abstract
The utility model discloses an outdoor high voltage isolating switch. The utility model has the purpose to provide an outdoor high voltage isolating switch in which the contact mode of contact heads is improved, wire contact is changed into plane contact, and the stability and the reliability of energization are ensured. The utility model comprises a protective cover, electric conducting tubes, a left contact head and a right contact head, wherein the left contact head of the utility model is a contact finger seat which is connected to the end part of one of the electric conducting tubes, and is provided with a plurality of contact fingers; the right contact head is a high voltage isolating switch of a hammer-shaped contact head, and is connected to the end part of the electric conducting tube. The utility model is characterized in that the contact finger seat forms a U shape, and the bottom part is fixedly connected with the top ends of the electric conducting tubes in a stationary fit mode; the contact fingers are bent from bus bars, and form a thumb shape, and one side of each contact finger is provided with an opening; the upper sides of the contact fingers, and a contact finger pressing board are directly pressed tightly and fixed on the contact finger seat through screw bolts, so that plane contact is realized. Contact finger pressure springs are arranged in the contact fingers, and are supported between the inner walls of the contact fingers, and the contact fingers are matched with the right contact head in a high density plane mode. The utility model solves the problem that contact heads are burned by heating the contact heads to be deformed, and ensures the stability and the reliability of energization.
Description
Technical field
The utility model relates to a kind of high voltage isolator, is specially adapted to GW4A type, GW5A type outdoor high-voltage isolating switch, belongs to outdoor electric equipment.
Background technology
In the electric power system converting equipment, high voltage isolator quantity is maximum for number, existing isolating switch is in operation and all can finds the fingertip scaling loss in the maintenance annual spring and autumn, the scaling loss position is around the fingertip anchor point, especially fingertip end, its reason are that the width of contact was greater than the width of fingertip seat after isolating switch closed a floodgate, the back fingertip that closes a floodgate is strutted, and makes fingertip become line with the fingertip seat and contacts.Also having a kind of phenomenon is that the back contact that closes a floodgate bumps with fingertip, makes fingertip run off location, causes the positioning convex point of fingertip to touch to have formed a little with the fingertip seated connection and contacts.More than these two kinds of phenomenons all make in the gap of fingertip and fingertip seat and have dirt, contact resistance is increased, cause the fingertip scaling loss, the back energising that can't guarantee to close a floodgate is reliable and stable.
The utility model content
At the defective that exists in the above-mentioned technology, the purpose of this utility model provides a kind of line contact is contacted with point and is improved to the formula face contact that is fixed and clamped, and reduces the contact heating burnout, guarantees the outdoor high-voltage isolating switch that energising is reliable and stable.
For achieving the above object, the utility model has adopted following technical scheme: a kind of outdoor high-voltage isolating switch, comprise protective cover, contact tube, left and right sides contact, and the fingertip seat that be provided with some fingertips of left contact for being connected with a contact tube port is provided with spring in it; Right contact is the contact that is connected with another contact tube port, and its characteristics are: described fingertip seat is the U-shaped shape, and its bottom surface and described contact tube top are affixed; Described fingertip is the contact that curves thumb of a side opening, and the fingertip outside is fixed with a fingertip pressing plate by bolt with described fingertip seat and is connected; Be provided with the fingertip stage clip in the described fingertip, the fingertip stage clip is supported between the fingertip inwall; Described fingertip inboard is that the plane touches with described contact junction.
Above-mentioned high voltage isolator, its characteristics are: described fingertip seat and described contact tube are riveted by stationary fit.
Above-mentioned high voltage isolator, its characteristics are: described contact and described contact tube junction are the stationary fit riveted joint.
Above-mentioned high voltage isolator, its characteristics are: described contact is the capitate contact, and its both ends of the surface are arcwall face, are the plane in the middle of its arcwall face, and the plane of described capitate contact and fingertip inboard closely touch.
Above-mentioned high voltage isolator, its characteristics are: described contact, fingertip seat, contact tube are selected the red copper material for use, and fingertip is selected the fine copper material for use.
Above-mentioned high voltage isolator, its characteristics are: described protective cover is the dustpan shape, by being bolted on the fingertip seat.Described fingertip surface is coated with certain thickness hard silver layer, has self-lubricating function;
Described fingertip seat adopts and scalds process of tin, and scald on the surface certain thickness tin layer, when fingertip seat and fingertip and fingertip pressing plate also together, when connecting, satisfied fingertip seat and fingertip and closely cooperated and prevent the requirement of oxidation with bolt;
The utility model adopts the stationary fit pressure-riveting process to be connected with between contact, fingertip seat and the contact tube, makes it can realize the high density cooperation, becomes non-removable fixed connection structure, has guaranteed reliable mechanical performance and electric conductivity.
The utility model adopts and improves the fingertip frame mode, fingertip is set at an end opening, the thumb structure of other end sealing, its opening part upper and lower side inboard is plane, inside upper part is an arc shape, be fixed on the fingertip seat, its fingertip one side directly is pressed abd fixed on bolt on the fingertip seat on contact tube top, and opposite side withstands contact by fingertip stage clip end face in the fingertip seat hole, when closing a floodgate, contact enters between fingertip, the pressure of spring and fingertip self elastic force has solved under "on" position, and the width of contact is greater than the width of fingertip seat, the back fingertip that closes a floodgate is strutted, make fingertip become line and contact, cause loose contact, make the contact heating with the fingertip seat, the problem that causes contact to damage effectively guarantees the reliable and stable of energising of closing a floodgate.
