Description
Technical field
The utility model relates to power distribution network electrical equipment technical fields, and in particular to a kind of 10kV anti-misconnection disconnecting switch
Lock.
Background technique
Disconnecting switch is that one kind is mainly used for " isolated power supply, grid switching operation, to be connected to and cut off low current circuit ", nothing
The switching device of arc-suppression function.Disconnecting switch has the insulation distance for meeting prescribed requirement and apparent when quartile is set between contact
Disconnect mark；When coincidence is set, electric current under normal loop condition can be carried and exceptional condition is (such as short at the appointed time
Road) under electric current switchgear.It is typically used as high voltage isolator, i.e., voltage rating is in the disconnecting switch of 1kV or more, it is originally
The principles and structure of body is fairly simple, but since usage amount is big, functional reliability require it is high, to electric substation, power plant
Design, the influence established and be safely operated are larger.Disconnecting switch is mainly characterized by no arc extinguishing ability, can only be in no load
Divide in the case where electric current, close circuit.
Disconnecting switch plays an important role in distribution network construction maintenance process:
1, after separating brake, reliable clearance for insulation is established, the equipment or route that need to overhaul and power supply is obvious disconnected with one
It prescribes and separates, to guarantee the safety of service personnel and equipment.
2, according to operation needs, changing-over route.
3, it can be used to point, the low current in zygonema road, such as the charging current of casing, bus, connector, stub cable, switch
The capacitance current of equalizing capacitance, circulation and the exciting current of voltage transformer when double-bus changing-over etc..
4, it according to the concrete condition of different types of structure, can be used to point, the open-circuit excitation electric current of unification constant volume transformer.
Disconnecting switch is primarily adapted for use in the low voltage terminals distribution system such as private residence, building in low-voltage equipment.Major function: no
On-load disjunction with connect route.
1. being used for isolated power supply, high pressure repair apparatus and charging equipment are disconnected, make to have therebetween one obviously can be seen that it is disconnected
It prescribes.
2. disconnecting switch and breaker cooperate, need to carry out grid switching operation by system operation mode, to change system fortune
The row mode of connection.
3. to be switched on or switched off low current circuit.
One group of disconnecting switch is respectively installed in two faces generally before and after breaker, purpose be by breaker and isolated from power,
Form obvious cut-off point；Because breaker originally, using oil-break, oil-break needs often maintenance, therefore two sides are just
There is obvious cut-off point, in favor of maintenance；Under normal circumstances, outgoing line cabinet is powered downwards from bus above by switchgear,
It is to want and isolated from power, but sometimes, also have the possibility of incoming call behind breaker, such as that one group of disconnecting switch is needed before breaker
Counter by other loops is sent, counter the sending of the devices such as capacitor, therefore one group of disconnecting switch is also required to behind breaker.
Disconnecting switch is mainly used to the part that will need to have a power failure in high voltage distribution installation and is reliably isolated with live part, with
Guarantee the safety of service work.The contact of disconnecting switch is all open to have apparent cut-off point in air, and disconnecting switch does not have
There is arc-control device, therefore cannot be used to cut off load current or short circuit current, otherwise under high pressure effect, cut-off point will generate strong
Strong electric arc, and it is difficult self-extinguish, in some instances it may even be possible to arcing (relatively or phase fault) is caused, scaling loss equipment jeopardizes personal peace
Entirely, here it is the major accidents of so-called " on-load drawing disconnecting switch ".Disconnecting switch can also be used to carry out cutting for certain circuits
Operation is changed, to change the method for operation of system.Such as: it, can be with disconnecting switch by running circuit in double-bus circuit
It is switched on another bus from a bus.It is also possible to be used to operate the circuit of some low currents.
In maintenance of electrical equipment, an electrical separation is provided, and is one and is evident that cut-off point, to ensure
The personal safety of maintenance personnel.Disconnecting switch is unable to on-load operation: not energy band rated load or big load operation, Bu Nengfen,
Load current and short circuit current are closed, but has can operating with Smaller load and nonloaded line for arc-chutes.When general power transmission operation:
Disconnecting switch is first closed, it is rear to close breaker or load class switch；When power operation: first cut-off breaker or load class switch, it is rear disconnected
Open disconnecting switch.It is identical with other electrical equipments when selection, voltage rating, rated current, dynamic current, thermostabilization electricity
Stream etc. all has to comply with the needs of use occasion.The effect of disconnecting switch is to disconnect the circuit of zero load electric current to make to be overhauled
Equipment and power supply have apparent cut-off point, to guarantee that the safety of service personnel, disconnecting switch do not have special arc-control device cannot
Load current and short circuit current are cut off, so must can just open in circuit in the case where breaker disconnecting circuit with operation isolation
It closes.
By the difference of voltage class, keep apart extension and be divided into low voltage isolation switch and high voltage isolator, by disconnecting switch control
Wiring processed and respective circuit breakers are latched, and on-load can be effectively prevented and draw, close disconnecting switch.But keep apart in operation bus bar side
In pass and line side disconnecting switch, due to artificial origin, it is possible to cause operation order reverse, this is switch, switch operation original
It is then not permitted and one of the reason of cause the accident in electric system.To prevent isolator operation reversed order, to not having
It using the anti-error factory of procedure lock, stands, currently, isolator operation is all made of common insulated pull rod, distribution line interruption maintenance is high
Pressure disconnecting switch pull open after, the moving contact of switch is generally not charged, pull open rear moving contact downwards and answer it is perpendicular to the ground, with stationary contact
Head keeps maximum operating distance.The electric blocking measure of anti-misconnection, the moving contact of switch is not configured in distribution line disconnecting switch
There is no reliable anti-misconnection technical measures, in the case where strong wind, thick fog and artificial erroneous judgement maloperation, as line switching does not break
It opens, it is possible to the security risk by the anti-power transmission of high voltage isolator to interruption maintenance route occur, as distribution line contact is opened
Maintenance is closed, carries out two sides disconnecting switch once occurring accidentally to close, will lead to repair apparatus and send a telegram here suddenly, there are security risks.
