Step 2: current detector (27) is constantly operated and is detected to the current fluctuation in circuit, while will test knot again Fruit feeds back to controller (14), due to the presence of resistance box (12) and air pump (15), when current detector (27) detects electricity When electric current in road is lower, controller (14) controls air pump (15) starting, is stretched using air pump (15) control Pneumatic extension bar (16) Contracting, so that copper sheet contact (18) be driven to slide on groove (26), when copper sheet contact (18) sliding can by increasing or The quantity of concatenated resistance (24) is reduced to be adjusted to size of current, the adjustment fluctuated to circuital current is realized, works as overload When detector (29) detects that circuit overloads are even short-circuit, four hydraulic pump (8) startings are controlled by controller (14), are utilized Hydraulic pump (8) driving hydraulic telescopic rod (9) it is flexible come drive power supply box (3) along sliding slot (11) direction slide, to will connect Disconnecting circuit is separated between point (22) and coupling (6), is cut off the power;
Step 3: current detector (27) and overload detection (29) utilize respectively internal built-in power (31) analog circuit The required power supply used when operation, and current detector (27) and overload detection (29) constantly examine circuit It surveys, drives the flexible of hydraulic telescopic rod (9) to drive by controller (14) control hydraulic pump (8) after detecting that circuit restores Power supply box (3) resets, and in device operation, and heat emission fan (25) is driven by general supply (32) and operated, in general supply (32) it disconnects and disconnecting together therewith.
