Detailed description of the invention
In conjunction with the drawings and specific embodiments, the invention will be further described.Should be understood that these embodiments are merely to illustrate
The present invention rather than restriction the scope of the present invention.In addition, it is to be understood that after having read the content that the present invention lectures, this area
The present invention can be made various changes or modifications by technical staff, and these equivalent form of values fall within scope defined herein equally.
A kind of novel reactance type vacuum line pressure regulator, including the control of several gears, switch contact and control gearshift
Device, switch contact be connected with gear after by vacuum bubbles to output loading, be provided with contact circuit in vacuum bubbles, controller connects
Having catalyst, catalyst can control the break-make of contact circuit according to the signal that controller sends.
Traditional feeder voltage regulator is mainly made up of autotransformer, load ratio bridging switch, intelligent controller three part, adjusts
Pressure principle as shown in Figure 1, realizes automatic loaded voltage regulation, i.e. in accompanying drawing 1 by load ratio bridging switch regulation transformer voltage ratio
Shown realizes pressure regulation by coordinating between regulation switch contact and each gear.Owing to switch contact gear is directly contact,
Unprotected measure and do not have reactor, therefore electric arc produced by work process transfer gear shift position is unescapable, electric arc
Generation not only contact is had the biggest destruction, and make the time lengthening of disconnecting circuit also can cause circuit breaker, wink
Between huge energy may burning apparatus, and switch conversion and can not be connected across on a gear and otherwise can open circuit burn.Therefore,
Require that high-voltage switch gear can make arc extinction rapidly in the least closing container.As shown in Figure 2, in order to eliminate electric arc
Producing, the present invention adds several vacuum bubbles in circuit, and with the series connection of corresponding gear, each vacuum bubbles is utilized vacuum bubbles control
Switch contact and the break-make of gear.
As shown in Figure 3, vacuum interrupter is usually by insulation crust 5, corrugated tube 4, contact, conduction vacuum bubbles structure
The parts compositions such as bar, radome 3, fairlead, contact is divided into static contact 1 and moving contact 2, static contact 1 to connect static conductive rod,
Moving contact 2 connects moving conductive rod 6.The shell of vacuum interrupter is Dewar vessel, is again the insulator between dynamic/static contact.Ripple
Pipe is 4 one kinds of alloy elastic elements, and its tube wall is corrugated, can elongate along its axis or shorten, very under external force
In empty arc-chutes, a port of corrugated tube 4 is welded together with the flange on moved end flange center hole, and another port is led with moving
Electric pole 6 is welded together.So by the axial stretching of corrugated tube, moving conductive rod 6 can carry out axially-movable within the specific limits
And do not destroy the air-tightness of shell.In vacuum interrupter, the outside of corrugated tube 4 is vacuum, and inside is air, in corrugated tube 4
The draught head of outer one atmospheric pressure of existence, this pressure makes moving contact 2 be tightly pressed together with static contact 1, forms contact closing force.
The Main Function of radome 3 is to shield the metal vapors and molten drop produced in disconnected current course, and contact is at drop-out current
During, the vacuum arc between contact makes contact material generation metal vapors and drop (electric arc product) spray to surrounding, this
A little electric arc products are by the inner surface mainly depositing to radome.Without radome, electric arc product will deposit to
On insulation crust, destroy the insulation of shell.Radome 3 still prevents electric arc product and is reflected back contact gap, causes weight after arc
Combustion and repeated breakdown.Radome 3 can also make vacuum interrupter internal electric field be distributed ratio is more uniform, thus improve vacuum interrupter
Dielectric level.Dynamic and static conducting rod is interior contact head, the electric conductor that outer same major loop is connected.One end of static conductive rod is with quiet
Contact 1 is connected with soldering, and one end of moving conductive rod 6 soldering connects moving contact 2, and moving conductive rod 6 is through corrugated tube 4 and leads
To overlapping and stretching out insulation shell 5, the diameter of moving conductive rod 6 extension is less, and this is used to fill conductive clamp.Moving conductive rod 6
There is a screw at center, end, and this screw is used for being connected with machinery actuating system.Moving conductive rod 6 drives moving contact 2 to transport vertically
Move splitting or integrating lock action.
When controller sends gear shifting signal, send signal to catalyst simultaneously, the normally open contact Guan Bi of catalyst, make
380V contactor coil is energized, and arranges iron core in coil and produces magnetic force, is adsorbed by moving conductive rod 6, make moving contact 2 and stationary contact
1 separates, the action simultaneously of the most each vacuum bubbles, and the contact circuit in vacuum bubbles disconnects, and the most each gear loop disconnects, and therefore shifts gears
Time, will not produce electric arc between switch contact and gear, and because the contact inside vacuum bubbles is in vacuum state, also will not be because of
Disconnect Guan Bi for circuit electriferous state and produce electric arc.
After gear has changed, controller is signaled to catalyst, makes the normally open contact of catalyst open, catalyst line
Circle dead electricity, iron core magnetic force disappears, and in vacuum bubbles, moving contact 2 and static contact 1 close, and make gear circuit communication.
