Detailed description of the invention
With detailed description of the invention, this utility model is described in detail below in conjunction with the accompanying drawings.
A kind of double main disconnected nature isolation electric locomotive high pressure redundant circuit system that this utility model provides
Structure is as it is shown in figure 1, include the first pantograph 2 and laying respectively at electric locomotive 1 rear and front end
Two pantographs 3, the first pantograph 2 and the second pantograph 3 are connected respectively in the first main circuit breaker 4
With the end of incoming cables of the second main circuit breaker 5, the first main circuit breaker 4 and end of incoming cables of the second main circuit breaker 5
The first voltage transformer 6 and the second voltage transformer 7, the first main circuit breaker 4 also it are connected respectively
The common transformator accessing electric locomotive 1 after leading-out terminal parallel connection with the second main circuit breaker 5.
Specifically, the end of incoming cables of the first main circuit breaker 4 is connected with the first pantograph 2 side conducting rod, the
The end of incoming cables of two main circuit breakers 5 is connected with the second pantograph 3 side conducting rod.
Input wall bushing 9 after the leading-out terminal parallel connection of the first main circuit breaker 4 and the second main circuit breaker 5 to connect
Enter the transformator of electric locomotive 1.
First voltage transformer 6 is connected with the first main circuit breaker 4 end of incoming cables conducting rod, and the second voltage is mutual
Sensor 7 is connected with the second main circuit breaker 5 end of incoming cables conducting rod, the first voltage transformer 6 and the second electricity
The Secondary Winding output signal input controller 8 of pressure transformer 7, controller 8 is according to the first pantograph 2
With the primary voltage sample devices that the rise situation of the second pantograph 3 distributes input electric power locomotive 1 automatically
In 12, it is achieved the automatic conversion of voltage signal input.
When first main circuit breaker 4 closes a floodgate, the second main circuit breaker 5 separately, replaces original power locomotive high-voltage
The function of disconnecting switch, isolates the first pantograph 2 side main circuit；When second main circuit breaker 5 closes a floodgate,
First main circuit breaker 5 separately, replaces the function of original power locomotive high-voltage disconnecting switch, isolation second to be subject to
Pantograph 3 side main circuit.
The double main disconnected nature isolation electric locomotive high pressure redundant circuit system of one of the present utility model includes
