Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is described further:
Fig. 1 is line construction schematic diagram of the present utility model;
Fig. 2 is the circuit theory diagrams that the utility model user demarcation switch fault signal transmission unit divides.
Embodiment
As depicted in figs. 1 and 2, specific embodiment of the utility model comprises the block switch F1-F7 be arranged on line mains and branch line, be arranged on wire-outgoing breaker switch CB1 and CB2 of transformer output, be arranged on user demarcation switch FJ1 and FJ2 of high voltage customer side, be arranged between wire-outgoing breaker switch and block switch, between block switch and the fault detector of the intersection of main line and branch line, two time-controlling arrangements.Described user demarcation switch comprises the boundary switch controller for sending protection act signal and trip signal; and fault-signal dispensing device; two time-controlling arrangements are arranged between boundary switch controller and fault-signal dispensing device; the input of a time-controlling arrangement is connected with user demarcation switch protection actuating signal output, and the input of another time-controlling arrangement is connected with user demarcation switch trip signal output part.
The structure of two time-controlling arrangements is identical; illustrate for the time-controlling arrangement be connected with the protection act signal output part of described boundary switch controller below: time-controlling arrangement comprises an auxiliary relay KM1, a time relay KT1 and drive circuit; the coils from parallel connection of coils of described auxiliary relay KM1 and time relay KT1, as output contact after the normally closed contact series connection of the normal opened contact of auxiliary relay KM1 and time relay KT1.As the toggle connection points of described fault-signal dispensing device after the output contact series connection of two described time-controlling arrangements.
Drive circuit comprises optical coupler U1, MAC97A8 bidirectional triode thyristor T1, resistance R1, resistance R2, resistance R3 and electric capacity C1, be connected with the protection act signal output part of described boundary switch controller after the input series resistance R1 of described optical coupler U1 (the optical coupler U2 of the drive circuit of time-controlling arrangement is connected with the trip signal output of boundary switch controller), the control pole of controllable silicon T1 is connected after the output series resistance R2 of optical coupler U1, first electrode of controllable silicon T1 is connected with the electric power loop of the second electrode with described auxiliary relay and the time relay, controllable silicon T1 is made to be connected in the electric power loop of auxiliary relay and the time relay, the branch road that an electric capacity C1 and resistance R3 in parallel is connected on described controllable silicon T1.After the protection act signal output part of boundary switch controller sends signal, the electric power loop of controllable silicon T1 conducting auxiliary relay and the time relay, auxiliary relay and the time relay are started working.
