Abstract
The utility model relates to a vacuum load tapping switch used for the load tap changing of the neutral points of dry type transformers and in particular for the load tap changing of those dry type transformers with specifications of 50Hz and 12KV. A cabinet frame is internally fixed with an insulating board on which vacuum bulbs is fixed. Three vacuum bulbs are a group, pull rods controlling each group of vacuum bulbs is articulated with one end of a connecting rod, the other ends of all pull rods in a group are fixed with the same transmission shaft, all transmission shafts are articulated with the cabinet frame. Each end of each transmission shaft is fixed with a connecting lever, the other end of the connecting lever is articulated with a PTO shaft of a permanent magnetic actuator, and all permanent magnetic actuators are fixed on the cabinet frame. The utility model has the advantages of simple structure, free pollution, energy consumption or maintenance and is dedicated for the load tap changing of the neutral points of dry type transformers.
Description
(1), technical field
The utility model relates to a kind of load tapchanging vacuum on-load operation switch of dry-type transformer neutral point that is used for, and is used in the dry-type transformer on-load voltage regulation of 50HZ, 12KV grade especially.
(2), background technology
At present, because the domestic load tapchanging on-load tap changer of neutral point that also is not specifically designed to dry-type transformer, so oily formula on-load tap changer is mostly adopted in the on-load voltage regulation of dry-type transformer now, the result has lost many advantages of dry-type transformer, cause a lot of occasions not use, for example explosion-proof, set fire, pollution and domestic user be to the inaccurate occasion of using of the electric equipment of oil, therefore causes outstanding dry-type transformer to be difficult to be equipped with on-load voltage regulating device.
(3), summary of the invention
In order to overcome the shortcoming of prior art, the utility model provides a kind of vacuum on-load operation switch, and it is specifically designed to the neutral point on-load voltage regulation of dry-type transformer, simple in structure, pollution-free, no energy consumption, non-maintaining, be used with the power network monitoring system and can realize the on-load voltage regulation Automatic Control.
The technical scheme in the invention for solving the technical problem is: cabinet support internal fixation insulation board, fixing vacuum bubbles on the insulation board, three is one group, the pull bar of every group of control vacuum bubbles is hinged with an end of a connecting rod respectively, the other end of all connecting rods in same group and same power transmission shaft are fixed, all power transmission shafts are all hinged with the cabinet support, one end of each power transmission shaft is fixed a connecting lever, the power output shaft of the other end of connecting lever and a permanent magnet mechanism is hinged, and all permanent magnet mechanisms all are fixed on the cabinet support.
Realize dry-type transformer on-load voltage regulation owing to adopt permanent magnet mechanism to drive vacuum bubbles, thus simple in structure, pollution-free, no energy consumption, non-maintaining.Be specifically designed to the neutral point on-load voltage regulation of dry-type transformer.
(4), description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the utility model front view;
Fig. 2 is the utility model left view.
(5), embodiment
As shown in Figure 1, 2, cabinet support 1 internal fixation insulation board 8, on the insulation board 8 fixedly 3, three vacuum bubbles of vacuum bubbles 3 be one group, level is uniform.The pull bar 6 of every group of control vacuum bubbles 3 is hinged with an end of a connecting rod 4 respectively, and the other end of all connecting rods 4 in same group is fixed with same power transmission shaft 2, and all power transmission shafts 2 are all hinged with cabinet support 1.One end of each power transmission shaft 2 is fixed a connecting lever 7, and the power output shaft of the other end of connecting lever 7 and a permanent magnet mechanism 5 is hinged.All permanent magnet mechanisms 5 all are fixed on the cabinet support 1.Totally 12 groups on described vacuum bubbles 3, pull bar 6, connecting rod 4, power transmission shaft 2, connecting lever 7 and permanent magnet mechanism 5 annexations and structure.
During use, the contact of vacuum bubbles 3 is electrically connected with the neutral point of dry-type transformer to be controlled, the coil of permanent magnet mechanism 5 is electrically connected with the power network monitoring system.When line voltage is higher, the power network monitoring system will start permanent magnet mechanism 5, and by connecting rod 4, power transmission shaft 2 and connecting lever 7 control vacuum bubbles 3, be used for increasing the coil turn of dry-type transformer, line voltage be reduced control voltage to keep inconvenience substantially.Vice versa.
Claims (2)
