Abstract
This utility model discloses a high voltage disconnector conducting switch, which substantially comprises a left conducting bar and a right conducting bar which connect an input connecting block and an output connecting block respectively through two conducting belts, a static ground connector and a connecting block. The left conducting bar and the right conducting bar and their fingers and contacts employ an integral conformation with one equipped with an open finger and the other with a closed contact. A large amount of man-hour expenses are saved due to the integral modeling conducting bar. Temperature rise due to a plurality of contacts is reduced and heating and deformation due to bad contact is completely solved. The design fully utilizes the function of electrical power and the finger clips more closely the contact with the effect of electrical power when short-circuit current occurs. 13.5 kg copper dosage is saved for each switch comparing with the traditional disconnector.
Description
Technical field
The utility model relates to the improvement technology of high voltage isolator current-carrying part, is specifically related to a kind of New High Voltage Isolating Switch electric installation.
Background technology
Outdoor high-voltage isolating switch is one of electric equipment the most frequently used in the ultra-high-tension power transmission line.Thoroughly do away with the relative position of edge pillars on pedestal according to every phase two, high voltage isolator commonly used at present can be divided into two kinds on V-type and erect type structure substantially.No matter be that V-type or its primary structure of erect type high voltage isolator are essentially identical, exactly every two three single-pole switchs that thoroughly do away with the edge pillars that are equipped with mutually are installed in column and prop up on the crossbeam of erecting certain altitude, every phase two is thoroughly done away with the edge pillars with current-carrying part transmission input, output current; With crank, connecting rod insulation column and operating mechanism are linked together, constitute link gear; Pull operating mechanism and drive every two thoroughly doing away with the edge pillars and rotate in opposite directions mutually, realize the separation and the closure of insulation column top operator by connecting rod and crank.High voltage isolator mainly is made up of current-carrying part, insulator, underframe running part, earthed switch and operating mechanism five major parts.The current-carrying part of prior art mostly adopts structure as shown in Figure 1 and Figure 2, comprises terminal block 1, is located at out conductive strips 3, conducting rod 4 in the irdome 2, left and right contact tube 5,9 and fingertip 7 thereof, contact 8, and fingertip seat 6.There is the processing cost height in this structure because parts; Especially conducting rod 4 and contact tube 5 and terminal block 1, and nearly 15～20 of the fingertip 7,8 of left and right contact tube 5,9 and pad, movable breaker point and contact points between the contact tube 5, exist long-time running to occur contacting bad easily, loop resistance increases, the galvanic circle is heated up too high, even the defective of galvanic circle scaling loss.
The content of utility model
At the prior art above shortcomings, the purpose of this utility model provides a kind of simple in structure, high voltage isolator electric installation of reducing contact point, reducing cost.
The purpose of this utility model is achieved in that the high voltage isolator electric installation, mainly comprises left and right sides conducting rod, ground connection fixed contact and terminal block, and left and right sides conducting rod connects input, output wiring board by two conductive strips respectively; Two conductive strips respectively have fixedly crimping place with input, output wiring board and left and right sides conducting rod respectively, and the ground connection fixed contact is connected with conducting rod; Left and right conducting rod and its fingertip, contact all adopt integral structure, and one is provided with open fingertip, and another is closed contact.
Further improving is that described left and right sides conducting rod is respectively plank frame; The open fingertip outside is provided with the stainless steel stage clip.
Compared to existing technology, the utlity model has following advantage:
1, left and right conducting rod all adopts the integral structure, and promptly conducting rod and fingertip are root timber material global formations, have reduced manufacturing procedure, have saved a large amount of work time costs;
2, whole galvanic circle has only four fixed contacts, has reduced five times than the isolating switch contact point of traditional structure; Because contact point is few, has reduced the temperature rise that causes because of the contact, phenomenons such as the heating that thorough termination causes because of loose contact, distortion;
3, make full use of electrodynamic effect in the design, when being short-circuited electric current, fingertip under electrodynamic effect, clamp contact more closely; Under identical rated current, every of the isolating switch of the amount ratio traditional structure of copper material is saved 13.5kg.
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.

Embodiment
Embodiment 1: as shown in Figure 3, high voltage isolator electric installation of the present utility model, mainly comprise left and right sides conducting rod 10,18, ground connection fixed contact 11 and terminal block 13, left and right conducting rod 10,18 connect input, output wiring board 13 by two conductive strips 12 respectively; Two conductive strips 12 respectively have fixedly crimping place A, a B with input, output wiring board 13 and left and right sides conducting rod 10,18 respectively, and ground connection fixed contact 11 is connected with left conducting rod 10 by screw; Left and right conducting rod 10,18 and its fingertip, contact all adopt integrated copper coin deformation processing to form, and one is provided with open fingertip 14, and another is closed contact 17; Left and right sides conducting rod 10,18 is respectively plank frame.Clearly, the whole loop of this structure has only four fixed contacts and a pair of movable breaker point.Fixed contact is that conductive strips 12 respectively have fixedly crimping place pressure A, a B with terminal block 13 and left and right conducting rod 10,18; Movable breaker point is the open fingertip 14 of left and right conducting rod 10,18 and the two movable breaker point C of place of closed contact 17.Because contact point is few, has reduced the temperature rise that causes because of the contact, phenomenons such as the heating that thorough termination causes because of loose contact, distortion.
Embodiment 2: on the basis of embodiment 1, be provided with the magnetic padlock plate 16 of stainless steel stage clip structure by screw 15 in open fingertip 14 outsides.When being short-circuited electric current, fingertip 14 is under electrodynamic effect like this, and more closely clamp contact 17 has guaranteed the reliability of work.Referring to Fig. 4, Fig. 5, because the effect of ground connection fixed contact 11 and moving contact, it is safe and reliable with the separating brake galvanic circle to close a floodgate, and it is bad to have avoided long-time running contact to occur, increases the adverse consequences that resistance causes the too high appearance of loop temperature rise.Dotted line is the separating brake track among Fig. 5.
