Utility model content
In order to solve above-mentioned technical problem, it is arranged side by side that the utility model provides a kind of new 10kV electric substations voltage transformer
Wiring construction, on the one hand ensure that not run equipment not charged, while ensure that handcart connects voltage circuit pushing running status,
Solve potential safety hazard.
The utility model is achieved in that a kind of new 10kV electric substations voltage transformer of offer wiring construction arranged side by side,
For dual power supply, double inlet wires, segmentation disrupted configuration, an inlet wire master is set gradually on an inlet wire termination by cabinet breaker change-over switch
Contact and an inlet wire master receive cabinet handcart position contact, two inlet wire masters are set gradually on two inlet wire inlet wire terminations and is turned by cabinet breaker
Change make and break contact and two inlet wire masters receive cabinet handcart position contact.
Compared with prior art, the utility model has the advantage of, as the master for accessing double inlet wires (inlet wire and two inlet wires)
After by cabinet breaker change-over switch contact, during changes of operating modes, it is ensured that not running side Secondary Circuit of Potential Transformer quilt
It is reliable to disconnect, it is ensured that it is not charged not run equipment, while it is to ensure that handcart is being pushed away by cabinet handcart position contact to access main
Enter running status and connect voltage circuit.

Specific embodiment
In order that the purpose of this utility model, technical scheme and advantage become more apparent, below in conjunction with the accompanying drawings and implement
Example, is further elaborated to the utility model.It should be appreciated that specific embodiment described herein is used only for explaining
The utility model, is not used to limit the utility model.
The security hidden trouble of 10kV electric substations voltage transformer wiring construction arranged side by side, this reality in order to solve prior art
It is dual power supply, double inlet wires, segmentation disconnection with new there is provided a kind of new 10kV electric substations voltage transformer wiring construction arranged side by side
Structure, with reference to Fig. 1, is provided with 1PT handcart positions contact 8 and 1 weight motor type relay 10 on an inlet wire, be provided with two inlet wires
2PT handcart positions contact 9 and 2 weight motor type relays 11, switching handle 13, segmentation cabinet breaker are additionally provided with the wiring construction and are connect
Point 3, segmentation cabinet handcart position contact 6, staged isolation cabinet handcart position contact 7 and 3 weight motor type relays 12, this new design weight
Point is to set gradually an inlet wire master on an inlet wire termination to be received cabinet hand by cabinet breaker change-over switch contact 1 and an inlet wire master
Truck position contact 4, two inlet wire masters is set gradually on two inlet wire terminations and is received by cabinet breaker change-over switch contact 2 and two inlet wire masters
Cabinet handcart position contact 5.
When the utility model runs, with reference to Fig. 1, Fig. 2 and Fig. 3, dual power supply is powered simultaneously when being normal, and block switch exists
, in on-state, 3 weight motor type relay contacts 16 are disconnected for open position, 1 weight motor type relay contact 14 and 2 weight motor type relay contacts 15
The equipment such as open state, every section of protection device gather the voltage transformer voltage of respective section and use, when a certain incoming power dead electricity,
Automatic throw-in equipment of emergency power supply action, output contact is main by the automatic tripping of cabinet breaker by dead electricity side, and output contact will be segmented
Cabinet breaker automatic closing, goes out dead electricity side specific electric load and is powered simultaneously by opposite side electric power incoming line, now dead electricity side protection device
Voltage Deng equipment will lose voltage due to former incoming power dead electricity, loss of data be caused, so must be by dead electricity side
The voltage of the equipment such as protection device is switched on opposite side electric power incoming line voltage transformer simultaneously, to ensure dead electricity side protection dress
The normal accurate operation of equipment such as put, now because of certain side incoming power dead electricity, 1 weight motor type relay contact 14 or 2 move again after
Electrical equipment contact 15 is in off-state, while 3 weight motor type relay contacts 16 are in on-state, it is ensured that the equipment such as two sections of protection devices
Collection voltages use active primary voltage, now because decompression side Secondary Circuit of Potential Transformer is by decompression side inlet wire master by disconnected
Road device contact disconnects, i.e. 1 inlet wire master is disconnected by the inlet wire master of circuit breaker contact point 1 or 2 by circuit breaker contact point 2, it is ensured that voltage is mutual
The high-pressure side 18 of sensor 17 is not charged, it is ensured that unsafe factor does not occur.
