Abstract
The invention relates to a tapping switch of a transformer and a non-excitation tapping switch for a grounding transformer. The non-excitation tapping switch comprises a gear device connected with static contacts, wherein the static contacts are two rows of parallel static contacts, the static contacts are mounted on insulation rods, the gear device is arranged between the two rows of static contacts, the gear device comprises two tooth bars engaged with a gear, the tooth bars and the insulation rods are parallel mutually, and the two tooth bars are in sliding connection with the corresponding insulation rods through a fixing frame. The non-excitation tapping switch is advantaged in that control on non-excitation tapping switching of the two rows of static contacts can be realized, and easily-generated problems of different or asynchronous shifts in the prior art are solved.
Description
Technical field
The present invention relates to the shunting switch of a kind of transformator, particularly to the off circuit tap changer of a kind of grounding transformer.
Background technology
Present stage, off circuit tap changer used in grounding transformer is two WST type switches, is separately mounted under the case lid of grounding transformer, and every switch corresponding connection grounding transformer Z respectively connects two parts of winding.Current such design in use has the disadvantage in that one is to take the space of case lid bottom relatively greatly, and particularly less when grounding transformer capacity, case lid lower space has in limited time, often difficult arrangement；Two is to use two switch costs high；Three is maloperation easily occur, and when the gear of two switches is not positioned in same gear, the voltage of three-phase windings will produce phase shift, cause voltage error.
Summary of the invention
The problem to be solved in the present invention is the deficiency overcoming background technology, it is provided that a kind of simple in construction, easy to operate, security reliability is high, and can effectively reduce the off circuit tap changer of grounding transformer cost.
The present invention is to be achieved through the following technical solutions: a kind of grounding transformer off circuit tap changer, including the geared system being connected with static contact, described static contact is set to the static contact that two rows are parallel to each other, and static contact is arranged on insulating bar, is provided with geared system between two row's static contacts；Described geared system includes two tooth bars engaged respectively with a gear, and tooth bar is parallel with insulating bar, and two tooth bars are all slidably connected with corresponding insulating bar by fixed mount.
Further, described gear is fixed with operation handle.
Further, described fixed mount is bolted on tooth bar.
The off circuit tap changer of the present invention, operating process is as follows: rotating operating handle, make pinion rotation, wheel and rack engagement drives the tooth bar together with being separately fixed at two row's static contacts to move, article two, tooth bar moving direction is contrary, moving contact on tooth bar contacts with static contact respectively, realize controlling replacing without excitation tap of two row's static contacts simultaneously, effectively prevent the gear easily occurred in existing design to differ or nonsynchronous defect, and only with a switch, not only take up room little, be also greatly reduced cost.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention.
Fig. 2 is the cross-sectional view of the present invention.
In figure, 1 static contact, 2 insulating bars, 3 gears, 4 tooth bars, 5 fixed mounts, 6 operation handles.
Detailed description of the invention
The invention will be further described below in conjunction with the accompanying drawings, but not as a limitation of the invention.This embodiment switch feature is to be set to static contact 1 two rows, and two row's static contacts 1 are parallel to each other, and static contact 1 is arranged on insulating bar 2.Concrete, the spacing between contact determines according to electric pressure, depending on the quantity of contact is according to pressure regulation progression, when range of regulation variation is at ± 5%V, for often arranging every 4 contacts mutually；It is often to arrange every 6 contacts mutually when range of regulation variation is at ± 2 × 2.5%V.Being provided with geared system between two row's static contacts 1, geared system includes gear 3 and tooth bar 4, and tooth bar 4 is also configured as two tooth bars 4, parallel between two tooth bars 4, and tooth bar 4 is the most parallel with insulating bar 2.Article two, tooth bar 4 is positioned at gear 3 both sides, engages with gear 3 respectively.Tooth bar 4 connects through a fixed mount 5 with insulating bar 2, and fixed mount 5 one end is fixed together with tooth bar 4 by bolt, and the other end is slidably connected with insulating bar 2, i.e. fixed mount 5 can on insulating bar 2 slidably.Structure and the fixed mount 5 of fixed mount 5 are existing with being slidably connected in existing off circuit tap changer of insulating bar 2, repeat no more here.Also fixing connection one operation handle 6 on the gear 3 of geared system.
The off circuit tap changer of the present embodiment, operating process is as follows: rotating operating handle 6, gear 3 is made to rotate, gear 3 engages with tooth bar 4 and drives the tooth bar 4 together with being separately fixed at two row's static contacts 1 to move, article two, tooth bar 4 moving direction is contrary, moving contact on tooth bar 4 contacts with static contact 1 respectively, realize controlling replacing without excitation tap of two row's static contacts 1 simultaneously, effectively prevent the gear easily occurred in existing design to differ or nonsynchronous defect, and only with a switch, not only take up room little, be also greatly reduced cost.
Embodiment described above, the simply one of the present invention more preferably detailed description of the invention, the usual variations and alternatives that those skilled in the art is carried out in the range of technical solution of the present invention all should comprise within the scope of the present invention.
