Circuit theory diagrams:

1, lightning protection, anti-surge part

Civil power is by L, N, the input of GND section.Single-pole switch S1 is switched on or switched off being connected of socket and electrical network phase line.Hot overcurrent breaker protector of RJ1 and F1 protective tube have been formed because of the output short circuit, or the protection of overcurrent.The High frequency filter system that L1, L2, C1 form, the High-frequency Interference pulse in the filtering electrical network also can prevent that high-frequency impulse that follow-up electric equipment produces from scurrying in the electrical network simultaneously.When occur thunder and lightning moment superhigh pressure and electrical network in surge, during situations such as overvoltage, the RV1-RV6 piezo-resistance can the moment conducting, makes the hot overcurrent vreaker of RJ1, F1, F2 protective tube etc. make corresponding insurance action.

2, ground connection, the phase line indicating section

R2-R6, Q1, LED1, D1 have constituted because imperfect earth does not have ground connection, and phase line and zero line connect anti-warning indication.R2, R3, R4 are the biasing resistor of Q1.R5, R6 are the current limiting pressure-limiting resistance of LED1.D1 guarantees that the back bias voltage of Q1 is 0.About 7V.D2 is LED1, and Q1 provides the direct voltage of need of work.Q1 is as far as possible with the triode of high-amplification-factor, so very faint base current, or even induced voltage can make the Q1 conducting, so the upper offset resistance R 2 of Q1, the contact of R3 must could guarantee that Q1 ends when the emitter of Q1 is on same current potential.When ground wire does not have ground connection, or during loose contact, all can make the base stage of Q1 present the state of high potential, the Q1 conducting, LED1 lights.Equally, phase line and zero line connect inverse time, also make the base stage of Q1 become the high potential conducting, and LED1 leads with lighting by Q1.

3, socket output socket

Present principles figure has designed 7 sockets, and concrete quantity can be determined according to actual needs.Civil power is through lightning protection, and anti-surge behind the High frequency filter, is divided into 4 the tunnel.The 1 road socket P1 is independently one group, does not control the switch of other socket power supplys, also is not subjected to the control of main socket and other current taps.The main socket P2 of the elementary access of L linear flow overcurrent instrument transformer T1 of the 2 road socket by detecting the electric current (being power detection) of current transformer T1, decides the 3 road P3-P4, the switching time of the 4 road P5-P7 socket power supply.LED2 and current-limiting resistance R1 are the general supply indication.LED3 and current-limiting resistance R21 are the 3 road P3, the power supply indication of P4.LED4 and current-limiting resistance R22 are the power supply indication of the 4 road P5-P7.

4, power detection part

The induced voltage of the secondary generation of current transformer T1 after R7 and adjustable resistance VR1 clamper, by rectifier bridge D3 rectification, obtains a direct current voltage after the C4 filtering, enter in the voltage comparator of being made up of IC1.The loop current of this sampling voltage and socket P2 is directly proportional.IC1 gets final product than integrated package with voltage ratio.Sampling voltage is connected on the IC1/a in-phase input end by divider resistance R8.Compare with the voltage of the inverting input of IC1/a.R12, R13 are the inverting input divider resistances of IC1/a.R14R15 is an IC1/a output divider resistance, simultaneously voltage after partial is input to the IC1/b in-phase input end.R16, R17 are the inverting input divider resistances of IC1/b.When sampling voltage is input to the IC1/a in-phase input end, when sampling voltage is lower than the voltage of IC1/a inverting input, the IC1/a output low level, in like manner, the output of IC1/b also is a low level.When sampling voltage was input to the IC1/a in-phase input end, when sampling voltage was higher than the voltage of IC1/a inverting input, IC1/a exported high level, and in like manner, the output of IC1/b is also exported high level.The switching circuit of back just can be made corresponding switch motion according to the high low value of level, determines the switching time of 3,4 road socket power supplys.C8 is used for delaying time the terminal voltage of R15, and promptly the in-phase input end voltage of IC1/b makes this voltage not suddenly change, and prevents the misoperation that main socket P2 causes the back switching device at the impulse current of connecting moment and other disturbance currents.When main socket power-off, but the turn-off time of

C8 delay control

3,4 road power supplys.By the different voltage comparison point of comparator IC1 is set, can make main socket P2 in the different capacity section, control the 3 the tunnel, the switching time of the 4 road power supply and on-off mode.

5, current tap power supply sequence switch part

Selector switch S2 is the mode of operation that is used for being provided with 3,4 road socket power supplys.Concrete mode of operation can freely be provided with according to needs, and in present principles figure, S2 is during as for 1 grade, and 3-4 road (P3-P7) socket power supply is not controlled by main socket P2, is normally open.S2 is as for 3 grades, and 3-4 road (P3-P7) socket power supply is not controlled by main socket P2 yet, is the normal off state.When S2 kept off as for 2,3-4 road (P3-P7) socket power supply was controlled by main socket P2.In present principles figure, when IC1/b output high level, Q2, Q3 conducting, relay K 1, K2 adhesive, the power connection of the 3 road socket P3-P4 and the 4 road socket P5-P7.When the IC1/b output low level, Q2, Q3 ends, relay K 1, K2 disconnects, and the power supply of the 3 road socket P3-P4 and the 4th socket road P5-P7 disconnects.R18, R19, C9 and R20, C10 are respectively Q2, the R C time constant delay circuit of Q3.As R20＞R18, C9＞C10, R20 * C10＞R18 * C9, and behind C9, meet a suitable resistance R19 and link to each other with the Q2 base stage, during IC1/b output high level, after one section time-delay, the conducting of Q2 elder generation, conducting behind the Q3, during the IC1/b output low level, after one section time-delay, Q3 ends earlier, ends behind the Q2.Just, during IC1/b output high level, the 3 tunnel (P3-P4) socket power supply is connected earlier, connect behind the 4 tunnel (P5-P7) socket power supply, during the IC1/b output low level, the 4 tunnel (P5-P7) socket power supply disconnects earlier, disconnects behind the 3 tunnel (P3-P4) socket power supply, thereby reaches the order of simulating the manual control switch.The switch order time circuit of 3-4 road socket power supply also can be used other times IC, and single-chip microcomputer is controlled.The switching device of 3-4 road socket power supply also can adopt controllable silicon according to needs, solid-state relay.

6, circuit low-tension supply part

The power unit of present principles figure has adopted by C4, and R9 forms the resistance-capacitance depressurization mode, also can adopt Switching Power Supply and common transformer mode according to needs.Again by rectifier bridge D4, after the C5 filtering, after R10 and the Z1 voltage stabilizing, the one road supplies with relay uses, another road by R11 and three terminal regulator IC2 after, offer comparator and partly use.
