Embodiment
Referring to accompanying drawing, a kind of overvoltage, overcurrent, electric leakage, the lightning protection multifuctional solar, city's electric protection controller, include cabinet 1, be respectively equipped with entrance hole 3 and wire hole 7 on the cabinet 1, insulating base 8 is installed in the cabinet 1, comprise the A.C. contactor 9 that is fixed on the insulating base 8, voltage transformer 23, A, B, C phase line wiring bronze medal 10,11,12, a zero line wiring bronze medal 13, ground connection bronze medal 14 and the circuit board 15 that is integrated with the detection control circuit, introduce three phase lines and a zero line respectively from the entrance hole 3 of cabinet 1, serial connection A.C. contactor 9 and after zero line passes voltage transformer 23 on three phase lines, the corresponding A that inserts, B, C phase line wiring bronze medal 10,11,12 and zero line wiring bronze medal 13, A, B, C phase line wiring bronze medal 10,11,12 and zero line wiring bronze medal 13 and ground connection bronze medal 14 between respectively and be connected to piezo- resistance 19,20,21,22, play the effect that suppresses overvoltage; A.C. contactor 9 is electrically connected with being integrated with the circuit board 15 that detects control circuit, is connected to outlet respectively on A, B, C phase line wiring bronze medal 10,11,12 and the zero line wiring bronze medal 13 and draws from the wire hole 7 of cabinet 1.
The present invention is further illustrated below in conjunction with accompanying drawing:
When overvoltage was leaked electricity, voltage transformer 23 was used for voltage detecting, and 1 ~ 4 end of voltage transformer 23 is the mains electricity input end, and 5 ~ 8 ends are the load of output termination.Circuit just often flows through L1, and the size of current of L4 equates that direction is opposite, and the magnetic flux that produces in voltage transformer 23 is cancelled out each other, and does not have induced voltage output among the secondary coil L.When electric shock or electric leakage take place when; from L1; the electric current of L4 is shunted over the ground by human body or electrical appliance; the part electric current no longer flows through L1; make L1; electric current among the L4 is no longer equal; the L two ends just produce certain induced voltage; this voltage is added to the 1st of IC1 through R0; between 2 pin; make the J1 conducting; the 7th pin elm of IC goes out high potential; the BT conducting; the J1 adhesive; be integrated with the j1-1 closure of the circuit board 15 that detects control circuit; give R4; high potential of R5 makes 3DG1; the quick conducting of 3DG2, delay circuit work this moment; circuit control J2 adhesive; j2-2-3 disconnects, through j2-3-4; j5-3-2 connects j4-1-8, J4 adhesive; j4-3-4 or 5-6 disconnect; A.C. contactor 9 coils (a); (b) voltage of losing the job, A.C. contactor 9 discharges, and civil power is cut off; the 2nd pin of metering timing circuit IC2 obtains high potential No. one time; beginning metering work for the first time, metering are can establish last J5 adhesive 1 ~ 6 time; j5-2-3 disconnects; j5-3-4 connects, the J4 adhesive, and A.C. contactor 9 discharges; civil power is cut off personal property and is protected, and row's barrier back manual reset could operate as normal.
Civil power is cut off during the J1 adhesive, when being integrated with the j1-1 closure of the circuit board 15 that detects control circuit, power supply can not be cut off power down because of civil power to the J1-2 energized to control circuit board, because C7, the flat value electricity of R4 exists, being added in the C7 both end voltage is 11V, make 3DG1, still conducting of 3DG2 " self-locking ", even L loss of voltage at this moment, J1 discharges, and J2 still keeps attracting state, being added in the C7 both end voltage passes through, R5,3DG, R7 forms discharge loop, discharge time about 25 ~ 60S, behind 25 ~ 60S, the C7 nearly 0V of crimping that powers on, 3DG1,3DG2 ends, so J2, J4 discharges, and A.C. contactor 9 adhesives restore electricity.If still have overvoltage or electric leakage this moment, flow through live wire L1 → L4 → R2 → L1 → piezo-resistance → ground, be added to IC1 at L time grade of voltage of inducting through R0,2 pin, IC1-7 pin high potential, BT conducting, thoroughly eliminate up to overvoltage and electric leakage, IC1 could end, and A.C. contactor 9 adhesives restore electricity.
