A method for replacing a high-voltage capacitance compensation cabinet capable of automatically replacing spare parts comprises the following specific steps:
firstly, when a voltage sensor and a current sensor detect that the voltage of current passing through a first capacitance compensation assembly deviates from a normal value, or a capacitor of the first capacitance compensation assembly bulges to open a rubber ring to press a pressure sensing switch, the problem of the first capacitance compensation assembly is shown, at the moment, the voltage sensor, the current sensor and the pressure sensing switch can trigger a stepping motor to drive a rotating column to rotate clockwise for half a circle, so that the first capacitance compensation assembly and the second capacitance compensation assembly in U-shaped connecting frames at the left side and the right side of the rotating column are exchanged in position, namely the first capacitance compensation assembly is separated from a circuit, the second capacitance compensation assembly is embedded into the U-shaped conducting frame through a conducting column and is connected into the circuit, and the induced voltage sensor or current sensor simultaneously enables a stepping motor to extend upwards for a set distance through a relay to enable an extrusion column to rise to a position for extruding a first key switch, therefore, the first key switch enables the first wireless signal transmitter to start to transmit a wireless signal to the remote receiving terminal, and causes the first signal lamp to send a signal, so that remote related workers can conveniently solve the replacement motion of the component at the corresponding position in the current cabinet body, which belongs to a non-emergency situation, and can arrange proper time and personnel to overhaul, when the capacitor on the capacitance compensation component II replaced in the circuit is also bulged to trigger the pressure sensing switch, or the voltage sensor and the current sensor detect that the voltage current is abnormal, the stepping electric telescopic rod can be triggered again, the stepping electric telescopic rod drives the extrusion column to rise upwards again, because the length of the extrusion column is larger than the distance between the first key switch and the second key switch, the upper end and the lower end simultaneously extrude the first key switch and the second key switch after the extrusion column rises again, the second wireless signal transmitter and the first wireless signal transmitter are enabled to run synchronously, so that the first signal lamp and the second signal lamp on the remote receiving terminal are simultaneously lighted, at the moment, the emergency condition is met, and a worker needs to stand before to repair the emergency when obtaining a signal prompt;
when the first capacitance compensation component and the second capacitance compensation component exchange positions, the U-shaped connecting frame at the position of the first capacitance compensation component is embedded into the second U-shaped embedding groove of the containing box, so that the first capacitance compensation component enters the containing box, the linkage iron plate just faces the magnet and the position of the third key switch, the magnet attracts the linkage iron plate by magnetic force, the linkage iron plate is extruded onto the third key switch by the extension of the connecting telescopic rod, the third key switch enables the air pump to be started, the inert gas in the inert gas storage tank is sucked out and is guided into the containing box by the through pipe to act on the first capacitance compensation component, the combustion and explosion phenomena are avoided, meanwhile, a part of the fire extinguishing inert gas is shunted into the hollow cavity by the through pipe, and the reciprocating electric push rod is enabled to perform telescopic motion by the third key switch simultaneously, in the process, the piston pressing plate continuously reciprocates in the piston cylinder, the inert gas entering the hollow cavity is firstly sucked and then pressurized, and is sprayed onto the first capacitance compensation assembly from the spray hole, so that the inert gas impacts the first capacitance compensation assembly to act;
thirdly, when the second capacitance compensation component is connected into the cabinet body and causes a problem, the extrusion column rises and extrudes on the second key switch, the pressure induction switch or the voltage inductor and the current inductor on the capacitance compensation component II cause the stepping motor to be started again, so that the capacitance compensation assembly two and the capacitance compensation assembly connected at the upper side rotate clockwise again around the rotating column, meanwhile, the second key switch causes the first common electric telescopic rod to extend leftwards, so that the side baffle plate and the transverse baffle plate seal the first U-shaped embedding groove, thereby avoiding the influence on other normally operating components caused by the fact that the capacitance compensation component rotates alternately to the inside of the cabinet body, protect the internal portion of cabinet, the second key switch causes the ordinary electric telescopic handle of second to extend downwards simultaneously, blocks that the U type link frame is rotatory, causes the first and second card of capacitance compensation subassembly in the U type link frame to stop at the external portion of cabinet.
