Abstract
The utility model relates to a spring pressure-connecting type electric connection which is convenient for assembly of a voltage transformator and can ensure reliable transportation of the voltage transformator; in a shell for being charged by insulating gas, an electric-conducting tube, a spring, a contact terminal, a nut and a contact terminal base are sequentially assembled; the spring is adopted for ensuring reliable pressure connection between the contact terminal and the contact terminal base. By adopting the electric connection, the electric-conducting tube can be conveniently connected with a high-voltage terminal rigidly, thus increasing stability; meanwhile, the electric-conducting tube is elastically connected with a shield cover, thus effectively reducing the effect on coils when shaking appears in the transportation.
Description
(1) technical field
The utility model relates to being electrically connected of a kind of power equipment use, especially can realize the supporting structure that connects with the voltage transformer internal high pressure of GIS (gas insulated switchgear).
(2) background technology
At present, the supporting connection with the voltage transformer internal high pressure of known GIS is made up of Mume flower contact, radome, contact tube, high-field electrode, wherein contact tube one end is fixed and is linked to each other with instrument transformer high pressure winding, the other end passes the Mume flower contact that radome connects the high-field electrode place, and the clamping force by Mume flower contact self realizes being electrically connected.But Mume flower contact is an elastic construction partly, can occur rocking in transportation, because of contact tube one end is fixed on the coil, thereby might make coiler part produce displacement, causes electric field distortion, influences the safe operation of equipment.
(3) summary of the invention
Might be in the existing electric connection structure transportation in order to overcome because of rocking the deficiency that causes the coil displacement, the utility model provides a kind of electrical connection of new construction, this electrical connection is not only easy to assembly, and can improve transportation stability, can effectively avoid making coil displacement to occur, guarantee the long-term safety operation of equipment.
The technical scheme that its technical problem that solves the utility model adopts is: an end of conducting rod is fixed on the high-field electrode, the other end is provided with the contact of a band spring, fix a contact base on the radome, adopt the thrust of spring that contact is closely contacted with contact base.Contact tube, high-field electrode and device housings are rigidly connected by bolt, good stability.
The beneficial effects of the utility model are: simple in structure, parts are easy to process, can be easy to realize assembling, and transportation stability is good.
(4) description of drawings
Fig. 1 is the vertical section structural map that the spring crimp type is electrically connected.
1. contact tubes among the figure, 2. spring, 3. contact, 4. contact base, 5. nut, 6. radome
(5) embodiment
Below in conjunction with drawings and Examples the utility model is further specified.
According to shown in Figure 1, the design's realization is that contact tube (1) is fixed on the conductor of high-field electrode, spring (2) assembles at contact tube (1) other end with contact (3), nut (5), contact base (4) is fixed on the radome (6), contact (3) contacts with contact base (4), and spring (2) pressure guarantees that two elements reliably is electrically connected.Spring is made by the compression of carbon steel cold coiling, and the spring wire diameter generally about 1mm, made by copper material by contact, and contact tube, nut all can be by simple machining moulding.
The design can be widely used in realizing that coil is connected with the reliable of high-field electrode in the connection of voltage transformer internal high pressure.This structure is easy to assembly, transportation reliability height.
Claims (3)
1. a voltage transformer spring crimp type is electrically connected, and mainly by shell, contact tube, spring, contact, nut, contact base are formed, and it is characterized in that: adopt spring to make between contact and contact base and reliably be connected.
2. a kind of voltage transformer spring crimp type according to claim 1 is electrically connected, and it is characterized in that: contact tube one end is fixed on the conductor that is communicated with high-field electrode, and spring, contact, nut are fixed on the other end of contact tube, and contact base is fixed on the radome.
