The first relay 21 for whether powering off of detection current supply circuit 1, and for detect current supply circuit 1 whether the second relay of short circuit
22, power failure lamp 10 is connected with first relay 21, excessively stream instruction is connected with second relay 22
Lamp 8, when current supply circuit 1 breaks down, if because circuit is powered off caused by open circuit, now power failure lamp 10 is by point
Bright, if because being powered off caused by short circuit, now excessively stream indicator lamp 8 will be lighted, and event occur in order to be determined more accurately
The current supply circuit 1 of barrier, therefore be equipped with every current supply circuit 1 line signal 9, the line signal 9 respectively with institute
State the first relay 21 and the second relay 22 is connected.
The relay includes the magnet coil 3 being connected on current supply circuit, and the control positioned at the top of magnet coil 3
Loop 4 processed, has been sequentially connected in series power supply 12, contact 11 and movable switch 5 in the control loop 4, and the control loop 4 passes through
Contact 11 is connected with indicator lamp, under normal circumstances movable switch 5 be disconnect, whole control loop 4 be in off state, only when
When current supply circuit 1 breaks down, corresponding movable switch 5 can just be closed so that control loop 4 is connected, corresponding indicator lamp point
Bright, one end of the movable switch 5 is provided with shell fragment 6, and contact 7 is provided with the front end of the shell fragment 6, and the magnet coil 3 is located at
The lower section of contact 7, the shell fragment 6 in the first relay 21 is in the lower section of movable switch 5, in the second relay 22
Shell fragment 6 be in movable switch 5 top.
Its operation principle is：In normal work, the movable switch 5 on the first relay 21 and the second relay 22
