The GW5-type disconnecting switch grounding knife-switch support of the utility model is advantageous in simple structure and convenient installation and use, and can effectively relieve the phenomenon of the downward shift of the center of gravity of a conducting rod of a GW5-type outdoor disconnecting switch grounding knife-switch.
Description
Technical field
This practicality belongs to power equipment technical applications, specifically a kind of GW5 type isolating switch earthing bracket.
Background technology
For guaranteeing the normal operation of GW5 type outdoor disconnector, the earthing conducting rod of GW5 type outdoor disconnector and the angle of homonymy post insulator remain in the scope of 90 ° of left and right conventionally, generally with left-right deviation, are no more than 2 ° and are advisable.But the special design structure due to its earthing, As time goes on earthing conducting rod center of gravity under the effect of self gravitation can down be offset gradually, the angle that can make conducting rod and homonymy post insulator is considerably beyond the deviation range (as shown in Figure 1) of 2 °, when putting equipment in service time long, the deviation range of angle sometimes even can 10 °～15 ° left and right.
Generally under normal circumstances, the earthing divide-shut brake course of action of GW5 type isolating switch is such: during combined floodgate, earthing operating mechanism half-twist, drive its earthing conducting rod to rotate same angle to the direction of homonymy post insulator, the moving contact of conducting rod end is engaged smoothly with the fixed contact on insulator top; Otherwise separating brake process.Moving down of earthing conducting rod center of gravity will inevitably cause earthing divide-shut brake stroke angles to become large, standard value considerably beyond 90 ° of left and right, so just make earthing conducting rod earthing in the situation that rotating 90 ° close a floodgate not in place, the dynamic and static contact of its earthing can not good contact, has the potential threat of the accident of bringing out.
The present invention is intended to solve the design defect of easily bringing out operability fault existing in the design of GW5 type outdoor disconnector earthing in transformer station.Research staff is not changing under the prerequisite of original equipment operation principle and design size, for the faultiness design of the distinctive project organization of GW5 type outdoor disconnector and existence a kind of Support bracket that can effectively alleviate GW5 type outdoor disconnector earthing conducting rod decentralization phenomenon.
Summary of the invention
The technical problem that the utility model solves has been to provide a kind of GW5 type isolating switch earthing bracket, and this utility model is simple in structure, easy to install, can effectively alleviate GW5 type outdoor disconnector earthing conducting rod decentralization phenomenon and occur.
For solving the problems of the technologies described above, the utility model GW5 type isolating switch earthing bracket, it is characterized in that, comprise triangle bracket body, described right-angle side one side near triangle bracket body is provided with the fixed head for fixed triangle shape bracket body, described fixed head is fixed to one another and is connected by being arranged at fixed head and bolt of long stem between triangle bracket body, another right-angle side of described triangle bracket body is provided with expansion joint, and described expansion joint is threadedly connected on A-frame body.
Described expansion joint is adjustable telescopic joint.
The upper end of described expansion joint is provided with rubber mount.
The beneficial effects of the utility model are: the utility model GW5 type isolating switch earthing bracket can effectively be avoided due to GW5 type outdoor disconnector earthing conducting rod decentralization, when the earthing of the GW5 type outdoor disconnector causing closes a floodgate, earthing closes a floodgate not in placely, and the situation that the dynamic and static contact of earthing can not good contact occurs.The advantages such as it has simple in structure, easy to install, and manufacturing cost is low.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is described in further detail:
Structural representation when Fig. 1 is existing GW5 type outdoor disconnector earthing use;
Fig. 2 is structural representation of the present utility model;
Fig. 3 is the structural representation of the utility model while being used in combination;
In figure: 1-triangle bracket body, 2-fixed head, 3-bolt of long stem, 4-expansion joint, 5-rubber mount, 6-pedestal channel-section steel, 7-earthing conducting rod.
Embodiment
As shown in Figure 2, a kind of GW5 type of the utility model isolating switch earthing bracket, it comprises triangle bracket body 1, described right-angle side one side near triangle bracket body 1 is provided with the fixed head 2 for fixed triangle shape bracket body 1, described fixed head 2 is fixed to one another and is connected by being arranged at fixed head 2 and bolt of long stem 3 between triangle bracket body 1, another right-angle side of described triangle bracket body 1 is provided with expansion joint 4, the upper end of expansion joint 4 is provided with rubber mount 5, described expansion joint 4 is adjustable telescopic joint, described expansion joint 4 is threadedly connected on A-frame body 1.
As shown in Figure 3, during use, triangle bracket body 1 is fixed on the pedestal channel-section steel 6 of GW5 type outdoor disconnector by bolt of long stem 3 and fixed head 2, when the earthing conducting rod 7 of GW5 type outdoor disconnector is during in open position, the fulcrum of active force is transferred to the contact position of expansion joint and ground connection conducting rod 7 by earthing conducting rod 7 rotating shaft positions, the earthing conducting rod 7 gravity arm of forces shorten, the rotating shaft place mechanical stress arm of force is elongated, rotating shaft place can be reduced by mechanical stress size greatly like this, thereby the phenomenon of effectively having alleviated earthing conducting rod 7 decentralizations occurs.
The main body frame of triangle bracket body 1 adopts the good triangular structure of stability, and installation aspect has adopted the mode that fixed head combines with bolt that the pedestal channel-section steel 6 of the main body frame of triangle bracket body 1 and GW5 type outdoor disconnector is closely connected and fixed.
In addition, earthing conducting rod 7 highly inconsistent problems while installing for the scene of solving, adjustable for height expansion joint 4 is set on triangle bracket body 1, fine setting by expansion joint 4 can realize very easily triangle bracket body 1 and regulate with the distance that contacts between earthing conducting rod 7, thereby reaches a good support effect.
When alleviating breaking-closing operating; impact dynamics when earthing conducting rod 7 contacts with triangle bracket body 1; expansion joint 4 ends that arrange on triangle bracket body 1 have installed the rubber mount 5 of 2 centimetres of left and right additional, and then strengthen the outer field protection of earthing conducting rod 7 plating zinc on surface.
GW5 type isolating switch earthing bracket can promote certain angle by the center of gravity of earthing conducting rod 7 by force, makes it restore to the standard value range of 90 ° of left and right.When operating mechanism half-twist, earthing dynamic/static contact can be along engaging like this.
Except the technical characterictic described in above-mentioned specification, be the known technology of those skilled in the art.
