Abstract
The utility model discloses a kind of shunting switch controller for main transformer pressure regulation, comprise controller base and PCB control board, controller base is fixed with V-type draw-in groove, V-type draw-in groove is made up of two the curved downwards shell fragments be oppositely arranged, correspondingly in the bottom of PCB control board front and back be provided with multiple deposited copper contact be connected, two shell fragments of V-type draw-in groove contact with the deposited copper contact at front, the back side on PCB control board respectively.The utility model has the advantages that: rational in infrastructure, easy to use, PCB control board is clipped in the middle by V-type draw-in groove, decrease the probability occurring oxidation, more firmly, contact performance is better in the contact of the deposited copper contact that can ensure PCB control board and V-type draw-in groove, voltage regulator controllers is made to export pressure regulation order more stable, the phenomenon occurring pressure regulation " tripping " can be greatly reduced, avoid the generation of power events (accident), thus ensure the qualification rate of power system voltage.
Description
Technical field
The utility model relates to main transformer voltage regulator controllers, specifically a kind of shunting switch controller for main transformer pressure regulation.
Background technology
Main transformer is most important electric equipment in electric power system, plays the effect of electric energy transmitting and regulation voltage, is to determine that can electric power system one of the key factor of safe power supply; And voltage regulator controllers is the critical component determining main transformer pressure regulating performance, the quality of its performance will directly have influence on the voltage regulation function of main transformer.
Main transformer voltage regulator controllers is the control axis of main transformer, and the contact performance of draw-in groove directly will affect the normal operation of main transformer on the control board of voltage regulator controllers and base, so that directly affect the safety and stability of electric power system, the phenomenon be oxidized inevitably is there is in control board and draw-in groove under Long-Time Service, therefore, the design of draw-in groove is most important.The contact of control board and draw-in groove is bad, and main transformer can be caused to occur " tripping " in running.Therefore, the shunting switch controller developing a kind of function admirable is conducive to the safe operation of main transformer, ensures power supply reliability.
Summary of the invention
The purpose of this utility model is for the deficiencies in the prior art, and a kind of shunting switch controller for main transformer pressure regulation of improvement is provided, it is rational in infrastructure, easy to use, the contact of control board and draw-in groove is good, the phenomenon occurring pressure regulation " tripping " can be greatly reduced, avoid the generation of power events (accident), thus ensure the qualification rate of power system voltage.
The technical scheme realizing the utility model object is:
A kind of shunting switch controller for main transformer pressure regulation, comprise controller base and PCB control board, unlike the prior art: controller base is fixed with multiple V-type draw-in groove, V-type draw-in groove is made up of two the curved downwards shell fragments be oppositely arranged, correspondingly in the bottom of PCB control board front and back be provided with multiple deposited copper contact be connected, two shell fragments of V-type draw-in groove contact with the deposited copper contact at front, the back side on PCB control board respectively, are firmly clipped in the middle by PCB control board.
The base of described controller is provided with terminal groove, and the through hole that the bottom surface of V-type draw-in groove is provided with in through hole and terminal groove overlaps, and arrange screw mandrel and be fixedly connected with terminal groove by V-type draw-in groove through through hole, the height of V-type draw-in groove is greater than the height of terminal groove.
The quantity of described V-type draw-in groove is identical with the quantity of terminal groove.
The utility model on-off controller is connected with external circuit by the deposited copper contact on PCB control board, and voltage regulating mode is that the instruction that PCB control board sends is transferred to external circuit through applying copper contact, is alternating current 220V by the voltage of deposited copper contact.
The utility model has the advantages that: rational in infrastructure, easy to use, PCB control board is clipped in the middle by V-type draw-in groove, decrease the probability occurring oxidation, more firmly, contact performance is better in the contact of the deposited copper contact that can ensure PCB control board and V-type draw-in groove, voltage regulator controllers is made to export pressure regulation order more stable, the phenomenon occurring pressure regulation " tripping " can be greatly reduced, avoid the generation of power events (accident), thus ensure the qualification rate of power system voltage.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of the utility model controller base.
In figure: 1.V type draw-in groove 1-1. first shell fragment 1-2. second shell fragment 1-3. through hole 2.PCB control board 2-1. applies copper contact 3. controller base 4. terminal groove.
Embodiment
Below in conjunction with drawings and Examples, content of the present utility model is described further, but is not to restriction of the present utility model.
Embodiment
With reference to Fig. 1-2, a kind of shunting switch controller for main transformer pressure regulation, comprise controller base 3 and PCB control board 2, controller base 3 is fixed with multiple V-type draw-in groove 1, V-type draw-in groove 1 is made up of the first curved downwards shell fragment 1-1 be oppositely arranged and the second shell fragment 1-2, correspondingly in the bottom of PCB control board 2 front and back be provided with multiple deposited copper contact 2-1 be connected, first shell fragment 1-1 of V-type draw-in groove 1 and the second shell fragment 1-2 respectively with front on PCB control board 2, the deposited copper contact 2-1 at the back side contacts, such PCB control board 2 is firmly clamped the centre of V-type draw-in groove 1, both contacts are more firm, contact performance is better, decrease the probability occurring oxidation.
The base 3 of controller is provided with terminal groove 4, the through hole that the bottom surface of V-type draw-in groove 1 is provided with in through hole 1-3 and terminal groove 4 overlaps, arrange screw mandrel V-type draw-in groove 1 to be fixedly connected with terminal groove 4 through equitant through hole, the height of V-type draw-in groove 1 is greater than the height of terminal groove 4.
The quantity of V-type draw-in groove 1 is identical with the quantity of terminal groove 4, and this example is 28.
On this routine PCB control board 2, the deposited copper contact 2-1 at front, the back side respectively has 14.
The central processing unit (CPU) of controller is fixed on PCB control board 2, and main transformer " pressure regulation " order is sent by CPU, is the process core of whole controller.
When in electric power system, voltage is lower, when needing by main transformer " downshift ", central processing unit (CPU) sends downshift command, command is to applying copper contact 2-1 place, shell fragment again through V-type draw-in groove 1 sends to external circuit, until main transformer gear shifting mechanism case, drive motors is by main transformer " downshift ".
