Description
Technical field
This utility model relates to the pole-mounted circuit breaker of a kind of dual power supply switching.
Background technology
At present, in the case of chopper one voltage transformer of configuration, first high-tension line inlet wire high tension cable accesses electricity
Pressure transformer is once held, then accesses chopper input terminal, and circuit breaker outlet terminal is connected with high-tension line outlet high tension cable,
Could normal power transmission, if voltage transformer breaks down, chopper will be lost the job power supply, also voltage transformer be torn open
Get off after changing can power transmission, therefore workload is very large, and needs long-time power failure, greatly reduces the reliable of power supply
Property.
Utility model content
The purpose of this utility model is to provide the pole-mounted circuit breaker of a kind of dual power supply switching, can realize dual power supply and switch not
Interruptedly supplying power, improves the reliability of power supply.
To achieve these goals, the technical solution of the utility model is as follows:
A kind of dual power supply switching pole-mounted circuit breaker, including voltage transformer YH(1), chopper (2), air plug HC(3), electricity
Cable (4), PT channel-section steel (5), PT cross-arm (6), power transfer relay XB(7) wire (8), terminal block (9), energy storage motor
(10), switching winding (11), closing coil (12), it is characterized in that: voltage transformer YH(1) by PT channel-section steel (5) and PT cross-arm
(6) be fixed on chopper (2), by two voltage transformer YH(1) secondary connection end by outdoor special RVVP band screen
The cable (4) covered causes the air plug HC(3 of chopper (2)), through air plug HC(3) transit to the dual power supply that chopper (2) is internal
Switching relay XB(7) input contact, by power transfer relay XB(7) power supply output contact causes end by wire (8)
On son row (9), then energy storage motor (10), switching winding (11) and closing coil (12) are caused the corresponding contact of terminal block (9), i.e.
Dual power supply can be realized and be switched to energy storage and divide-shut brake loop power supply, dual power supply uninterrupted power supply can be realized, improve power supply
Reliability.
The pole-mounted circuit breaker of described a kind of dual power supply switching, it is characterised in that: energy storage motor (10), switching winding (11)
It is installed on switch internal motor drive mechanism (13) with closing coil (12).
Beneficial outcomes of the present utility model is: compared to existing technology, and this utility model has the uninterrupted of dual power supply switching
Power supply, even if wherein a voltage transformer breaks down, do not result in line outage yet, for improve electrical network power reliable
Property, play positive facilitation.

13, motor drive mechanism
As shown in Figure 1-2, the pole-mounted circuit breaker of a kind of dual power supply switching, by two voltage transformer YH(1) it is fixed on PT
On channel-section steel (5), then be fixed on the top of chopper (2) by PT cross-arm (6), by two voltage transformer YH(1) secondary connect
Line end causes the air plug HC(3 of chopper (2) by cable (4)) in, the secondary of mutual induction of voltage is exported and is transitioned into chopper
Enclosure interior.
As shown in Figure 3-4, a kind of dual power supply switching pole-mounted circuit breaker, by wire (8) by air plug HC(3) on voltage
The secondary contact of transformer cause dual power supply switch relay XB(7) input contact, dual power supply is switched relay XB(7)
Output contact causes dead end of terminal block (9), is provided with energy storage motor (10), switching winding (11) on motor drive mechanism (13)
With closing coil (12), what wire (8) one end was welded on switching winding (11) and closing coil (12) exposes on terminals, separately
One end is also secured to opposite side dead end that terminal block (9) is corresponding with energy storage motor (10) wire end, can realize double
Power supply is switched to energy storage and divide-shut brake loop power supply, can realize dual power supply uninterrupted power supply, improves the reliability of power supply.
Claims (2)
