Abstract
The invention discloses a kind of shunting switch controller for main transformer pressure regulation, including controller base and PCB panel, V-type draw-in groove it is fixed with on controller base, V-type draw-in groove is made up of the most curved two shell fragment being oppositely arranged, corresponding in the bottom of PCB panel front and back being provided with multiple deposited copper contact being connected, two shell fragments of V-type draw-in groove contact with front, the deposited copper contact at the back side on PCB panel respectively.The invention have the advantage that rational in infrastructure, easy to use, PCB panel is clipped in the middle by V-type draw-in groove, decreasing probability oxidation occur, can guarantee that the deposited copper contact of PCB panel is more firm with contacting of V-type draw-in groove, contact performance is better, make voltage regulator controllers output pressure regulation order more stable, the phenomenon that pressure regulation " tripping " occurs can be greatly reduced, it is to avoid the generation of power events (accident), thus ensure the qualification rate of power system voltage.
Description
Technical field
The present invention relates to main transformer voltage regulator controllers, a kind of shunting switch controller for main transformer pressure regulation.
Background technology
Main transformer is most important electrical equipment in power system, plays transmission electric energy and the effect of regulation voltage, is to determine that can 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 influence the voltage regulation function of main transformer.
Main transformer voltage regulator controllers is the control axis of main transformer, and the panel of voltage regulator controllers and the contact performance of draw-in groove on base will directly affect the properly functioning of main transformer, so that directly affecting the safety and stability of power system, panel and draw-in groove inevitably occur the phenomenon of oxidation under life-time service, therefore, the design of draw-in groove is most important.Panel is bad with contacting of draw-in groove, 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, it is ensured that power supply reliability.
Summary of the invention
It is an object of the invention to for the deficiencies in the prior art, and the shunting switch controller for main transformer pressure regulation of a kind of improvement is provided, it is rational in infrastructure, easy to use, panel is good with the contact of draw-in groove, the phenomenon that pressure regulation " tripping " occurs can be greatly reduced, it is to avoid the generation of power events (accident), thus ensure the qualification rate of power system voltage.
The technical scheme realizing the object of the invention is:
A kind of shunting switch controller for main transformer pressure regulation, including controller base and PCB panel, unlike the prior art: on controller base, be fixed with multiple V-type draw-in groove, V-type draw-in groove is made up of the most curved two shell fragment being oppositely arranged, corresponding in the bottom of PCB panel front and back it is provided with multiple deposited copper contact being connected, two shell fragments of V-type draw-in groove contact with front, the deposited copper contact at the back side on PCB panel respectively, and PCB panel is firmly clamped in centre.
The base of described controller is provided with terminal groove, and the bottom surface of V-type draw-in groove is provided with through hole and overlaps with the through hole in terminal groove, arranges screw mandrel and is connected fixing to V-type draw-in groove and terminal groove through through hole, and the height of V-type draw-in groove is more than the height of terminal groove.
The quantity of described V-type draw-in groove is identical with the quantity of terminal groove.
Switch controller of the present invention is connected with external circuit by the deposited copper contact on PCB panel, and voltage regulating mode is that the instruction that PCB panel sends is transferred to external circuit through applying copper contact, is alternating current 220V by the voltage of deposited copper contact.
The invention have the advantage that rational in infrastructure, easy to use, PCB panel is clipped in the middle by V-type draw-in groove, decreasing probability oxidation occur, can guarantee that the deposited copper contact of PCB panel is more firm with contacting of V-type draw-in groove, contact performance is better, make voltage regulator controllers output pressure regulation order more stable, the phenomenon that pressure regulation " tripping " occurs can be greatly reduced, it is to avoid the generation of power events (accident), thus ensure the qualification rate of power system voltage.

Detailed description of the invention
Below in conjunction with the accompanying drawings present disclosure is described further, but is not limitation of the invention.
With reference to Fig. 1-2, a kind of shunting switch controller for main transformer pressure regulation, including controller base 3 and PCB panel 2, multiple V-type draw-in groove 1 it is fixed with on controller base 3, V-type draw-in groove 1 is made up of the first the most curved shell fragment 1-1 being oppositely arranged and the second shell fragment 1-2, corresponding in the bottom of PCB panel 2 front and back it is provided with multiple deposited copper contact 2-1 being connected, the first shell fragment 1-1 and the second shell fragment 1-2 of V-type draw-in groove 1 respectively with front on PCB panel 2, the deposited copper contact 2-1 at the back side contacts, so PCB panel 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 that oxidation occurs.
The base 3 of controller is provided with terminal groove 4, the bottom surface of V-type draw-in groove 1 is provided with through hole 1-3 and overlaps with the through hole in terminal groove 4, arranging screw mandrel to be connected fixing with terminal groove 4 for V-type draw-in groove 1 through equitant through hole, the height of V-type draw-in groove 1 is more 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 example PCB panel 2, front, the deposited copper contact 2-1 at the back side are respectively arranged with 14.
The central processing unit (CPU) of controller is fixed on PCB panel 2, and main transformer " pressure regulation " order is sent by CPU, is the process core of whole controller.
When in power system, voltage is relatively low, when needing " to be downshifted " by main transformer, central processing unit (CPU) sends downshift command, instruction transmission is to applying at copper contact 2-1, shell fragment through V-type draw-in groove 1 is sent to external circuit again, until main transformer gear shifting mechanism case, motor is driven " to be downshifted " by main transformer.
