It is pulled lower contracting.
By the program, owing to, two contacts clash into when, moving contact is in speed faster, the most permissible
Ensure to occur without due to the nearer sparking of long-time contact distance and electric arc, and owing to being knocked contact, there is bullet
Spring effect, spring plays energy-absorbing energy storage effect, and it is less that it clashes into vibration；Meanwhile, circuit disconnects when, also
Motion when realize, so, moving contact be knocked contact depart from time, at the beginning of moving contact has been provided with
Speed, more preferably avoids above-mentioned sparking and arc phenomenon；And employ telescopic pin, circuit after it is stable
Disconnect or closure state is safe and reliable.By the design to each telescopic pin, achieve the lock to circuit well
Fixed.

Under jointly the acting on of head spring (9) and described moving contact spring (3), described in be knocked contact (2) and described
Moving contact (1) entirety in the case of remaining engaged with moves right a segment distance, now, described moving contact (1)
Stretch with the described second left side vertical face of shank of spacer pin (7), the bottom of right flank contact, described dynamic touch
Head spring (3) is in extended state；Thus, described moving contact (1) and the described contact (2) that is knocked reach
Stable engagement state, high-tension circuit is in stable closure state；
When described high-voltage switch gear is in described stable closure state, described high-voltage switch gear can be as follows
And disconnect:
Bi. drop-down described second pull bar (73) from the lower end of described second pull bar (73) so that described second
The shank of flexible spacer pin (7) overcomes the elastic force of the second pin spring (72) and lower contracting；
Bii. moving contact (1) and described in be knocked contact (2) overall described moving contact spring (3) with
It is knocked described in and under the common effect of touch spring (9) and ejects to the right；When the described right side being knocked contact (2)
The bottom of side stretch with the described 3rd the left contact of shank of spacer pin (8) time, described in be knocked contact (2)
Stop motion, described moving contact (1) continues to move right, and the protrusion contact (11) of described moving contact (1) exists
Motion departs from in the middle part of the described right flank being knocked contact (2), it is achieved the disconnection of high-tension circuit；
Biii. under the control of described control module, right solenoid (5) powers on, and attracts moving contact (1)
Continuing to move right, and when described moving contact (1) moves, first stretches the shank of spacer pin (6) at it
Wedge shape tapered plane is depressed when acting on moving contact (1)；When the left lower of described moving contact (1) moves to institute
Stating first the stretch right vertical plane of spacer pin (6) with time right, first spacer pin (6) that stretches sells spring at it
(62) support frame as described above (12) is stretched out under effect；
Biv. under the control of described control module, electricity, described moving contact (1) under described right solenoid (5)
Left lower stretch with described first under the effect of described moving contact spring (3) spacer pin (6) right side erect
Straight plane contact；Thus, described moving contact (1) and described be knocked the disengaged position that contact (2) reaches stable,
High-tension circuit is in stable off-state；
