Detailed description of the invention
Fig. 1 is the structural block diagram of the utility model.
Specific embodiment
In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, below in conjunction with attached drawing and implementation
Mode, the present invention will be further described in detail, it should be appreciated that the specific embodiments described herein are only used
To explain the utility model, it is not used to limit the utility model.
A kind of preassembled transformer station high-pressure control device as shown in Figure 1, including voltage transformer 1, uninterruptible power supply 2,
High voltage load switch 3, DTU module 4,48V power module 5, control button 6；The input of the high voltage load switch 3 termination 10kV electricity
High pressure inlet wire is pressed, the output of the high voltage load switch 3 terminates the voltage transformer 1, the output end of the voltage transformer 1
The uninterruptible power supply 2 is connect, the output of the uninterruptible power supply 2 terminates the 48V power module 5, the 48V power module 5
Output termination DTU module 4 and high voltage load switch 3 electric brake, the electric brake control terminal of the high voltage load switch 3 is in parallel
4 signal output end of control button 6 and DTU module；High-voltage fuse is connected between the high voltage load switch 3 and voltage transformer 1
Disconnected device 7.
Specifically, crossing high-tension fuse 7 after high-pressure side 10kV incoming call and being protected again power transmission to voltage transformer 1, electricity
It presses mutual inductor 1 that 10kV voltage is converted into AC220V voltage, then powers simultaneously to uninterruptible power supply 2, uninterruptible power supply 2 has
Electric energy storage and output, the voltage after output are conveyed to 48V power module 5 and carry out direct current conversion, then supply electricity to DTU module 4
With the electric brake of high voltage load switch 3, control button 6 can control on the spot, can connect remote equipment by DTU module 4 and realize far
Journey manipulation.
In the event of a loss of power, if being overhauled, in the power free situation in scene, uninterruptible power supply can be used, by not
Uninterruptible power carries out inversion, and the DC power supply of storage is changed into AC220V power supply, is powered, reaches for DC power supplier
Purpose is controlled to high voltage load switch.
When 10kV power outage, inversion can be carried out by uninterruptible power supply, the electric energy of storage be converted, becoming can
The AC220V AC power source of control, then by 48V power module be changed into can field control and remote control DC power supply,
It may be implemented in 30 minutes and disjunction control realized to live high-voltage board, while related data record analysis is carried out to safety at power cut,
After power failure end or troubleshooting, high pressure restores electricity, and realizes on the spot or be remotely controlled power transmission.
The preassembled transformer station high-pressure control device reliable design of the utility model is reasonable, the controlling party with previous high-voltage board
Formula is compared, and may be implemented and to grasp field condition in time with remote control double control on the spot, analyze problem,
Site problems are quickly solved, rapid power transmission improves power transmission safety.
Embodiment described above is only that preferred embodiments of the present invention are described, not practical to this
Novel conception and scope is defined.Without departing from the design concept of the present utility model, ordinary people in the field couple
The all variations and modifications that the technical solution of the utility model is made, should fall within the protection scope of the present utility model, this reality
