Technical field：
The present invention have developed a kind of 35kV high-voltage thyristors series connection valve body electromagnetic actuator device, for 35kV high-voltage thyristor valve bodies high-low pressure every
From triggering with silicon controlled.
Background technology：
In high-voltage thyristor series connection valve body application, with the rising of electric pressure, the electric field intensity between electrode will more collect uneven, the meeting of neutralization
Generation corona discharge phenomenon, can make insulating part aging after not only producing noise jamming, and long-term corona, flashover fault occurs.Solve corona existing
What the application at present of the technology of elephant was ripe is to use high pressure light activated power thyristor, and its trigger is transmitted by light pricker, isolates high-low pressure by light pricker.But
High pressure light activated power thyristor is expensive, and general user is difficult to bear.If with Electromagnetic Drive ordinary high pressure controllable silicon valve body, low cost, mechanism be simple,
It is easy to maintenance, but the corona problem of driving means cannot be solved.Invention solves with the driving means of ordinary high pressure controllable silicon valve body in 35KV
Corona problem under environment.
The content of the invention：
It is an object of the invention to provide a kind of high-voltage thyristor series connection valve body electromagnetic actuator device for reducing corona under 35kV working environments.35kV is high
Pressure controllable silicon in serial connection valve body electromagnetic actuator device by epoxy resin cylinder, low-voltage driving line, short-circuit potential dividing ring, current transformer, etc. constitute.Ring
Oxygen resin column two ends are insulation full skirt, and low-voltage driving line is located at cylinder center, is run through by 4 squares of copper cash, a termination drive circuit other end
Ground connection.By 20 short-circuit potential dividing ring equidistant arrangements, short-circuit potential dividing ring is that ring-type copper mesh is embedded in cylinder for epoxy resin cylinder middle part, and by
Wire is drawn.A current transformer is covered on each potential dividing ring.Due to have between epoxy resin cylinder and current transformer air gap, plastics, iron core,
The different mediums such as copper cash, cause that Electric Field Distribution is very uneven easily to produce corona.Present invention employs short-circuit potential dividing ring cause epoxy resin cylinder with
The short circuit of above-mentioned different medium, and short-circuit potential dividing ring is relative with low-voltage driving line annular distribution so that Electric Field Distribution is uniform, so as to greatly improve corona
Phenomenon.
The current transformer of the present invention is coupled by same trigger current, and trigger current synchronism is good, it is ensured that every serial connection controllable silicon can be simultaneously turned on,
The trigger current controllable silicon punch-through that same period does not cause is avoided, the reliability of controllable silicon valve body is improve.
The present invention effectively improves the synchronism of high-voltage corona phenomenon and silicon controlled trigger current, reduces high-frequency electrical for the triggering of serial connection controllable silicon
Magnetic disturbance, improve once it is secondary between the class of insulation, reduce the volume and weight of driving means.
The invention has the beneficial effects as follows：
1 present invention effectively reduces corona phenomenon, reduces electric energy loss, reduces frequency electromagnetic waves to electronics due to adding short-circuit potential dividing ring
The interference of equipment, delay insulation ag(e)ing, strengthen once secondary insulating properties.
, by Electromagnetic Drive ordinary high pressure serial connection controllable silicon valve body, low cost, mechanism are simple, easy to maintenance for 2 present invention.
3 the technology of the present invention are advanced, cost performance is high, reliability is high, economic benefit is obvious, can be widely applied to the existing system of electric power network reactive power compensation
The transformation and upgrade of system.

Specific embodiment：
The present invention is the vitals in high-voltage large power thyristor electrical switch as shown in Figure 1, and high-voltage large power thyristor electrical switch is by microcomputer
Controller, electromagnetic actuator device, three part of controllable silicon in serial connection valve body composition.Microcomputerized controller output driving current signal, controls controllable silicon valve body
It is turned on and off.Electromagnetic actuator device major function is transmission driving current signal and isolation high-low pressure.Controllable silicon valve body is responsible for the conducting in loop and is closed
Close.
Microcomputerized controller output driving current signal during work, driving current signal flow through current transformer primary side by low-voltage driving line, and Jing is electric
Current transformer is coupled to secondary side, secondary side current signal triggering controllable silicon.Secondary outfan, a termination controllable silicon negative electrode, while connecing short-circuit partial pressure
Ring, another termination controllable silicon grid.
Low-voltage driving line connected with computer controller, Current Transformer Secondary side joint is high pressure, is mainly insulated by epoxy resin cylinder between them.
Short-circuit potential dividing ring is embedded in epoxy resin cylinder, the secondary outfan and controllable silicon negative electrode of its lead-out wire connection current transformer, short circuit epoxy
Medium between resin column and current transformer, makes electric field be uniformly distributed over the ground.When controllable silicon valve body is turned on, each short-circuit potential dividing ring current potential phase
Deng.When controllable silicon valve body disconnects, the voltage on each short-circuit potential dividing ring is uniformly distributed in ladder dress, and electric field is also evenly distributed over the ground.No matter lead
Logical or disconnection controllable silicon valve body, the electric field of short-circuit potential dividing ring is all to be uniformly distributed over the ground, so as to weaken corona phenomenon.
