Description
Technical field
The invention belongs to breaker technical field, particularly to a kind of chopper with reclosing function.
Background technology
Chopper refers to close, carry and cut-off the electric current under normal loop condition, and can close, regulation time
The switching device of the interior electric current carrying and cut-offfing under abnormal loop condition (including short circuit condition), chopper is typically by contact system
System, arc quenching system, operating mechanism, electrical apparatus release, shell etc. are constituted.Chopper can be used to distribute electric energy, infrequently starts asynchronous
Motor, carries out protection to power circuit and motor etc., when they occur serious overloads or the fault such as short-circuit and under-voltage
Time can automatic shutdown circuit, its function is equivalent to Fuse switch and crosses the combination of underheat relay etc., and in disjunction therefore
Typically need not after barrier electric current change parts.Low-voltage circuit breaker realizes the operating mechanism of splitting or integrating lock and is generally divided into manual operation
Mechanism and motor-operating mechanism are in low-voltage circuit breaker distant control field, general by motor-operating mechanism automatic brake separating
With combined floodgate low-voltage circuit breaker, thus realize to power circuit and the protection of motor.Motor-operating mechanism has motor to operate machine
Structure and two kinds of operation electriomagnet mechanism, it can be current Application comparison with the advantage of flexible that motor-operating mechanism has rotating speed
Many a kind of low-voltage circuit breaker motor-operating mechanisms.But, when motor-operating mechanism breaks down, electric motor operating mechanism is also
Needing automatic brake separating and the combined floodgate being manually operated mechanism to realize low-voltage circuit breaker, therefore, drive mechanism needs simultaneously full
Foot electric operating and the function of manual operation.
In prior art, the driving force of motor is transferred on the handle of chopper by many employing gear engagements, thus realizes
The combined floodgate sub-switching operation of chopper, is applied to the driving force of motor on the handle of chopper by the transmission of gear, such as China
Patent documentation CN102983016A discloses a kind of chopper manual/electric integral operating mechanism, and it includes being arranged on open circuit
First and second fixed plate covered in device, the lower section of described first fixed plate is provided with mobilizable separating plate, described separating plate

Electric operating process the following detailed description of the chopper described in the present embodiment with reclosing function:
Before circuit-breaker switching on-off, it is necessary to allow chopper detain again, i.e. to separating brake direction moving handle, just can be normally carried out point
Close a floodgate.Chopper is in vibration or without reason after separating brake, the most described breaker closing/on/off operation mechanism is in gate-dividing state, controls
Device detects product separating brake model, and described controller issues instructions to described motor 1, and described motor 1 turns clockwise, drive with
The co-axially fixed described swing handle 21 of output shaft of described motor 1 rotates, and the lobe 211 on described swing handle 21 also can be with described rotation
Handle 21 rotates, owing to described lobe 211 is enclosed within the described U-shaped opening of described slip handle 22 around the output shaft of described motor 1
In 222, thus described lobe 211 can apply a thrust to the inwall of described U-shaped opening 222, promotes described slip handle 22
The direction linear motion of the described gathering sill 221 arranged on described slip handle 22, meanwhile, due to described slip handle 22
Linear motion so that the described second blocking arm 22b of its lateral edge slides along described guide rail 41, and then opens with described fine motion
Closing the contact pad of 3, described contact pressurized, i.e. chopper are anchored to position again, send a signal to described controller, described controller control
System cuts off the power supply of described motor 1, and described motor 1 stops operating.Then controller sends instruction, described motor 1 inverse time again
Pin rotarily drives described swing handle 21 and rotates, and described lobe 211 promotes the circuit breaker handle connecting portion 8 of described slip handle 22 to move
Making product close a floodgate, described controller detects that switching signal, described motor 1 quit work.
When chopper needs to realize sub-switching operation, the above-mentioned combined floodgate on/off operation mechanism of the present embodiment is utilized to realize
Sub-switching operation, the separating brake process of operating mechanism is similar with above-mentioned making process, does not repeats at this.
The following detailed description of have described in the present embodiment reclosing function chopper During manual operation:
When electric operating breaks down or overhauls, need to use manual operation to carry out the/sub-switching operation that closes a floodgate, due to institute
The output shaft stating motor 1 is coaxially fixed together with described idle pulley 10 and described swing handle 21 by described resilient key 11, in using
When hexagonal handle is rotated into row manual operation in being inserted in described hole 12, described idle pulley 10 stress rotates, and drives described swing handle 21 to revolve
Turn, thus described lobe 211 promote the described U-shaped opening 222 of described slip handle 22 that described slip handle 22 is moved along a straight line,
Drive described circuit breaker handle connecting portion 8 thus pull circuit breaker handle and realize closing a floodgate.
Obviously, above-described embodiment is only for clearly demonstrating example, and not restriction to embodiment.Right
For those of ordinary skill in the field, can also make on the basis of the above description other multi-form change or
Variation.Here without also cannot all of embodiment be given exhaustive.And the obvious change thus extended out or
Change among still in the protection domain of the invention.
