Description

Technical Field

The invention relates to a conductive part of a high-voltage isolating switch, in particular to a wire outlet seat assembly of the high-voltage isolating switch, and a female contact assembly, a male contact assembly and a fracture assembly comprising the wire outlet seat assembly.

Background

The high-voltage isolating switch outlet seat component is a port for connecting a high-voltage isolating switch conductive part with an external equipment electric appliance, taking a double-column horizontal fracture isolating switch as an example, the conductive part is fixed on a post insulator through the outlet seat component, for convenience of operation, the post insulator of the high-voltage isolating switch can rotate through a flange base at the lower end, so that the conductive part at the upper end of the post insulator can rotate in a plane, the static external equipment transmits electric energy to a conductive component through the outlet seat, the other end of the conductive component is connected with a contact component, so that the isolating switch completes the opening and closing operation through the rotation of the post insulator, and the rotation range of the conductive part in the operation is generally about 90 degrees.

The high-voltage isolating switch is generally used outdoors for a long time, and an upper cover is covered outside the wire outlet seat assembly for avoiding the corrosion damage of rainwater, dust and external environment to the wire outlet seat assembly, reducing the electrical stability of equipment and even threatening the reliable operation of a power system.

The existing outlet seat component has the following three typical structures:

1. the wire outlet seat assembly is characterized in that a structure mode of a conical conductive roller and a spring is adopted, the conductive roller of the wire outlet seat assembly can form rotatable conductive connection between the inner shaft and the outer ring under the pressure of the spring, and the wire outlet seat assembly is electrically connected with the conductive member. The structure is flexible in rotation, but the structure is complex, the requirement on the sealing performance of the shell is strict, and the self-cleaning performance of the contact joint is poor, so that poor conductive contact between the roller and the conductive seat is easily caused, and a heating fault is generated.

2. The outlet seat component of the Z-shaped sliding contact structure is in rotating contact between the inner shaft and the outer ring of the conductor under the pressure of the Z-shaped sliding contact sub-spring, so that the outlet seat component can be in rotating contact with the conductor within a 90-degree range for conducting electricity.

3. The wire outlet seat component adopting a flexible connection and fixed connection mode is a wire outlet seat structure mode which is more used at present, the structure is that a lug boss is convexly and upwards arranged on one side of the flange surface and used for fixing the conductive component, a rotary bearing seat and a rotary shaft are arranged in the middle of the flange surface, a connecting end surface is arranged above the rotary shaft, a wire outlet plate is fixed on the connecting end surface, and a conductive column or tube is vertically integrated on the outlet plate, one end of the flexible connection is connected with the conductive component fixed on the boss by a bolt, the other end of the flexible connection is connected with the conductive tube or conductive column by a bolt, the conducting post and the outlet plate which is horizontally arranged are integrally (welded) formed, so that the outlet plate can rotate around the rotating shaft, the wire outlet plate can meet the requirement by rotating by about 90 degrees through the length setting of the flexible connection, and the wire outlet plate is electrically connected with the conductive member through the flexible connection.

In addition, an upper cover is arranged outside the wire outlet seat, so that the wire outlet seat component is formed.

As the load current of power systems increases year by year, the stability and reliability requirements on electrical equipment are also increasing.

At least two bolt connection interfaces exist in the wire outlet seat assembly, and compared with welding connection, the bolt connection is greatly increased in transmission resistance; in addition, according to the analysis of the running defects of outdoor equipment, the resonance and the temperature alternation caused by breeze can cause the loosening and heating of the bolt; since the outlet plate is extended from the lower plane and connected to the connecting shaft, the formed rotating structure is difficult to be completely sealed, the upper cover is opened at the lower part, and rainwater and corrosive gas corrode the bolt connecting interface from the lower part, which is not favorable for the stability of electrical connection.

The fixed closing plate 212 is formed in an arc shape fitted to the upper cover 211 and is fixedly attached at one end thereof to one side of the outlet plate 101 by bolts so that when the flange holder 5 is rotated to a 90 ° position (break assembly off position) with respect to the outlet plate 101, the fixed closing plate 212 shields the opening of the upper cover 211 exposed by the rotation of the flange holder 5 with respect to the outlet plate. The movable sealing plate 213 is substantially flat and disposed on the opposite side of the outlet plate 101, and the movable sealing plate 213 is pivotally connected to the upper and lower support plates of the rotating bracket 32 at one end near the outlet plate by a pivot pin 216, and when the flange bracket 5 is rotated to a 90-degree position with respect to the outlet plate, the other end of the movable sealing plate 213 can be inserted into the slit between the upper cover 211 and the terminal plate 103, and when the flange bracket is rotated to a horizontally extended position (fracture component engagement position) with respect to the outlet plate, the movable sealing plate 213 is consequently drawn out from the slit and shields the opening of the upper cover exposed by the relative rotation. Therefore, when the flange support rotates in a reciprocating mode between a horizontal extending position (fracture assembly joint position) and a 90-degree bending position (fracture assembly disconnection position) relative to the wire outlet plate, the movable sealing plate and the fixed sealing plate alternately shield the openings exposed at the two sides of the wire outlet plate, and a closed cavity is formed outside the wire outlet seat by matching the upper cover and the flange plate to isolate the wire outlet seat from the external environment, so that the internal components of the wire outlet seat 1 are prevented from being corroded and damaged by the external environment.

In order to simplify the process and save material, as shown in fig. 4, the rotating bracket 32 may also be formed by bending a metal plate in the manufacturing process. In addition, the fixed closing plate 212 may be welded to the vertical plate 323 side of the rotating bracket, or may be formed by extending the vertical plate 323 side of the rotating bracket, thereby simplifying the structure.

Through the structure, the outlet plate 101 forming the conductive loop and the flange support 5 can rotate relatively to meet the functional requirements of the isolating switch in the 'on' and 'off' operation, namely, the outlet plate 101 connected with the adjacent equipment can be kept still along with the rotation of the post insulator and the conductive member 61. Because the outlet plate 101 and the flexible connection 102 are welded into a whole, the outlet plate 101 and the conductive member 61 form an electrical connection loop, so that the number of bolt connection faces in the electrical connection loop inside the outlet base 1 is reduced to one, and the electrical stability of the outlet base 1 in outdoor operation is improved.

Second embodiment

Next, referring to fig. 5 and 6, the outlet block assembly 1 according to the second preferred embodiment of the present invention will be described in detail.

The second embodiment shown in fig. 5 and 6 is mainly different from the above-described first embodiment in that the outlet block assembly 1 is combined with the rod-shaped contact finger 62, thereby constituting a female contact assembly in which the rod-shaped contact finger 62 is directly connected to the outlet block assembly as a conductive member, simplifying the structure of the entire female contact assembly. Therefore, the following description focuses mainly on the differences between the two, and the same features are not described herein again.

In the second embodiment, a bar-shaped stylus finger is employed as the conductive member, whereby the pad 566 is provided, the bar-shaped stylus finger is provided on the opposite two side surfaces of the pad 566, the pad 566 is in a rectangular parallelepiped shape as a whole, and a through hole is provided through one side thereof. A cylindrical support 545 is provided on the side of the support plate 52 opposite the pad 566. The strut 545 may be inserted into the through hole of the pad. In order to press and fix the pad 566 in front of the support plate 52, the strut 545 is provided with a threaded hole at the front end, a stop pressure block 556 is arranged near the front end and is connected to the front end of the strut 545 through a screw 70 and a matching nut, the pressure block 556 is axially provided with a through hole and is provided with a stop tooth at the rear side, and the stop tooth is also arranged at the front end of the strut 545 and is matched with the through hole. On the other hand, the terminal board 103 of the outlet board is symmetrically arranged on the outer side of the pad from both sides, the rod-shaped contact fingers 62 are symmetrically arranged on the outer side of the terminal board 103 in a group of 6 side by side, clamping plates 572 are respectively arranged on the outer sides of the rod-shaped contact fingers 62, mounting holes are arranged at the upper and lower ends of the clamping plates 572, the two clamping plates on both sides are tightened through bolts, so that the rod-shaped contact fingers 62 are pressed with the terminal board to form electric connection, and the rod-shaped contact fingers 62 and the terminal board 103 are jointly fixed on both sides. Thus, the circular hole of the pad 566 is fitted over the strut 545, and the pad is coupled to the front end of the strut 545 through the hole of the press 556 by the bolt 70 and the nut. When the alignment of the break assembly (not shown) fixedly connected to the other end of the conductive member is completed, the nut on the bolt 70 is tightened to press the pressing piece 556 against the front surface of the seat plate 52, thereby fixing the conductive member.

Because the blocking teeth arranged on the pressing block 556 and the strut 545 prevent the pressing block from rotating in the circumferential direction, after the fracture assembly is adjusted, the pressing block 556 is pressed, so that the angle adjusting position of the conductive member can be accurately fixed on the wire outlet seat, and circumferential adjustment of the conductive member during installation and debugging is realized.

As shown in fig. 5, a nut of the screw 70 may be screwed at an opening of the conductive member outside the wire outlet base to fasten or adjust the connection of the strut and the pad 566, and thus, in order to simplify the structure and facilitate the installation and adjustment, the top plate 58 is integrally welded to the upper portion of the support base plate 52 instead of the detachable top plate 53, and a short shaft 31 is provided at a position where the top plate passes through the central axis MM, and the short shaft 31 may be fixedly connected to the top plate 58 by a screw. Correspondingly, a short shaft 551 is also fixedly arranged on the flange 51, and a mounting hole is also arranged at the other end of the top plate 58 to fix the upper cover of the protective cover.

Since the conductive member is a rod-shaped contact finger 62, the contact pressure provided is limited and related to the length of the rod-shaped contact finger 62, however, the structural size of the isolating switch determines the length of the contact finger, and the required contact pressure at the fracture cannot be satisfied. In order to meet the contact pressure required by the fracture, the fulcrum of the maximum bending moment can be moved forward, for this purpose, a partition plate 71 is arranged between the front side of the clamping plate of the rod-shaped contact finger 62 and the rear section of the contact zone, two partition plates 71 are arranged, each partition plate comprises a plate 711, the middle of each partition plate is provided with a long hole for adjustment, two branches 712 extend from one side of the outer edge of the plate 711, each partition plate 71 is further provided with a columnar stop bar 713, the branches 712 extending from the plate 711 are welded with the stop bar 713, so that a long and narrow channel is formed between the two branches 712 and the stop bar 713, the rod-shaped contact finger is enclosed in the channel from the outer side, and the free end of the rod-shaped contact finger obtains a stressed fulcrum. During assembly, the two partition plates 71 respectively vertically penetrate through the rod-shaped contact fingers and enable the plate-shaped plates 711 to be mutually superposed, the stop rods 713 on the two sides are abutted to the outer sides of the rod-shaped contact fingers, then the screw rods 70 are matched with the two nuts to tightly press the partition plates 71, the mutual distance between the stop rods 713 on the two sides is also fixed, so that the suspended ends of the rod-shaped contact fingers obtain stressed pivots, therefore, when the male contact is fitted into the opening of the female contact and expansion force is applied to the rod-shaped contact fingers 62, the stressed pivots of the rod-shaped contact fingers are moved to the stop rods 713, and under the condition that the bending moment and the stress applied to the roots of the rod-shaped contact fingers are not over limit, the contact pressure required by fracture can be met.

For the purpose of saving material and reducing weight, in this embodiment, the clamping plate 572 may be bent into a U-shaped cross section, and a guiding plate is welded on the outside of the clamping plate along the axis NN to ensure smooth movement of the movable sealing plate 213.

Other structures of the present embodiment are the same as those of the first embodiment, and therefore, will not be described in detail.

Thus, a bar-shaped female contact assembly of simplified construction is provided, which is particularly suitable for disconnector assemblies of disconnectors of 110KV and below.

Third embodiment

The plate-like contact 63 is a curved plate and is provided at its free end, i.e. the end that will be in contact with the female contact, with a convex cylindrical curved surface 631, whereby a matching breaking assembly can be formed with the female contact of the rod contact finger of the second embodiment.

The pair of plate-like contacts 63 constitute the male contacts of the breaking assembly to engage with the female contacts. Although the plate-like contact 63 is fixedly connected to the pad 566, since the pad is fitted over the strut 545 and pressed against the support plate by the pressing piece 556 via the bolt, the pressing piece 556 and the strut 545 are provided with teeth that prevent the pressing piece from rotating in the circumferential direction, and thus the circumferential angular position of the male contact can be adjusted.

Since the two flexible connections 102 are held outside the holder plate from both sides, the holder plate 52 can take the form of an integral plate, not necessarily a separate two-plate form, so that the two terminal plates 103 are inserted between the holder plate 52 and the conductive ends of the conductive members 64 from both sides of the holder plate 52, respectively, and are similarly fastened tightly together by bolts.
