Embodiment

Please refer to the calcspar of Fig. 1 office buildings electric appliance energy-saving circuit, by the original power of office buildings, illuminating line (main office space), branch the two poles of the earth are controlled separately, Surveillance center's every layer of each power and lighting of vertical shaft power and lighting distribution box control office buildings by every layer that is office buildings divides distribution box, and every layer of each power and lighting of office buildings divides distribution box to pass through the power supply of power unit energy-saving distribution box;

Please refer to the schematic diagram of Fig. 2 office buildings electric appliance energy-saving circuit, vertical shaft power and lighting distribution box is configured to automatically and manual two cover control circuits, vertical shaft power and lighting distribution box is configured in office buildings Surveillance center increases by two lines to each interlayer of office buildings circuit, carry out far distance controlled with 12V or 24V safety power supply by the circuit monitoring center, realize that regularly moment is disconnected, the purpose of closing, press manually or microcomputer on line control switch K1 (can do two contacts of microcomputer interlock in Surveillance center, also can start close, moving disconnected compound button), make KA obtain 12V or 24V low-voltage alternating-current electric forming closed-loop path by transformer secondary output, this moment, the change over switch of SCA was in automated location (diagram on-position), the coil electricity of auxiliary relay KA1, make the self-holding contact closure of its middle relay K A1, the coil of the coil of ac contactor coil KM and thermal relay KH forms the closed-loop path, A.C. contactor KM exchanges the closing of contact, makes the electricity of vertical shaft power and lighting consumer unit 2 be sent to power and lighting and divides distribution box 3.Wherein when change over switch is in manual position (drawn open position), press start button SF, the self-holding contact closure of A.C. contactor KM, the coil of A.C. contactor KM gets electric by KH formation closed-loop path, the action of the interchange contact of A.C. contactor KM makes the electricity of vertical shaft power and lighting consumer unit 2 be sent to power and lighting and divides distribution box 3.
