The overall operation principle according to the above-described first to fourth embodiments is as follows:
pneumatic alarm 23: the sealing piston arranged at the front end of the piston rod 233 pushes the gas in the vacuum cylinder 231 to the disc whistle 232, and the gas is discharged from the disc whistle 232 to generate noise;
the round whistle 232 is a conventional whistle principle: the sound is produced by the vibration of the air in the disk whistle 232, and the whistle mouth mainly makes the air flow impact against the opening gap of the disk whistle 232, so that the vibration of the air in the disk whistle 232 is caused.
In the initial state that the filter does not leak electricity: in the use process, the aluminum alloy filter shell 1 is connected with electrical equipment through a conductive grounding plate arranged on the double sub-chute legs 21; the pulley baffle 213 and the double-hole sleeve plate roller rod 215 are positioned in the penetrating groove 211, the insulating shell 214 does not cover the whole aluminum alloy filter shell 1 to cover rubber friction groove plates 243 arranged on two sides of the shielding, and the outer surface springs of the bending spring rod 241 are respectively extruded and compressed through the disc whistle 232 and the piston rod 233; the vacuum cylinder 231 and the piston rod 233 are respectively driven to be far away by the two insulating shells 214; the connection part of the wire bundle of the input end and the output end is inserted between the rubber sheets arranged in the middle of the rubber rolling rim 251, the rubber sheets and the rubber skin on the outer surface of the wire bundle generate friction force to prevent the wire bundle from exerting pushing force, the wire bundle cannot be moved, and then the smaller inner diameter ring of the conical internal thread hollow sleeve 252 is extruded to open the fastening sleeve 255 to be contracted inwards and closed, so that the output and input end connecting wires are fastened.
When the Y grounding capacitance inside the filter is damaged or the grounding wire bundle is damaged, the direct current voltage is reduced, a short circuit phenomenon occurs, meanwhile, when the grounding is damaged, the leakage current (positive electric object) carried on the aluminum alloy filter shell 1 and free electrons on the ground can move to the aluminum alloy filter shell 1 (positive electric object) to be neutralized, so that the aluminum alloy filter shell 1 (positive electric object) is not electrified, the electromotive force is zero, after the grounding is damaged, the neutralization between the free electrons on the ground and the aluminum alloy filter shell 1 (positive electric object) is finished, and the electromotive force is increased to enable the aluminum alloy filter shell 1 (positive electric object) to be electrified;
at this time, the strong through electromagnet bar 225 is generated by the electric wire electrically connected with the electric wire carried on the aluminum alloy filter housing 1, and the strong through electromagnet bar 223 is made to slide backward in the partition 224 by the magnetic force until the resistance electromagnet bar 223 is far away from the power-assisted spring 222 which limits and presses the outer surface of the double slide bar 221, at this time, the power-assisted spring 222 is sprung upward to push the double-hole sleeve plate roller bar 215 sleeved and sliding on the outer surface of the double slide bar 221, and synchronously drives the double-hole sleeve plate roller bar 215 to slide upward in the penetrating groove 211, meanwhile, the double-hole sleeve plate roller bar 215 drives the pulley baffle 213 to slide in the penetrating groove 211 to the inner shallow groove 212 by the insulating shell 214, when the pulley baffle 213 slides to the inner shallow groove 212, and the leakage current on the aluminum alloy filter housing 1 is transmitted to the power through the electric wire to the through electromagnet bar 217, the power-passing electromagnet block 217 is enabled to generate magnetic force, at the moment, the magnetic force of the power-passing electromagnet block 217 is used for adsorbing the magnet plate 216 connected to the pulley baffle 213, so that the two insulating shells 214 are synchronously close to and contacted with each other to further effectively wrap the aluminum alloy filter shell 1 of the power-passing electromagnet block, the situation that leakage current on the aluminum alloy filter shell 1 is shocked to professional operators and non-operators for overhauling is avoided, meanwhile, when the insulating shells 214 are not close to each other, the insulating shells 214 shield and protect an output interface and an input interface, the aim of preventing water from dripping to the interface and shielding part of dust is fulfilled, and meanwhile, the situation that the heat dissipation function of the aluminum alloy filter shell 1 is reduced is conveniently avoided under the condition that the existing insulating shells 214 are directly wrapped to the outer surface of the aluminum alloy filter shell 1;
when the two insulating shells 214 move towards the middle, the two insulating shells 214 respectively drive the vacuum cylinder 231 and the piston rod 233 to approach each other, when the two insulating shells 214 move to a horizontal position, the piston rod 233 enters the vacuum cylinder 231, at the moment, the two insulating shells 214 continue to move towards each other, the piston rod 233 is driven to move in the vacuum cylinder 231 to push air in the piston rod 233 to the disc whistle 232, and then the disc whistle 232 is driven by air and wind power to send out alarm sounds until the two insulating shells 214 are completely close to each other, and the alarm sounds are finished, so that the operation is convenient for warning staff that a filter has electric leakage, and further the operation of the filter connecting equipment is stopped emergently, so that alternating current components of a power supply can not be filtered, direct current voltage is reduced, and meanwhile, the condition that the connected equipment has short circuit damage is avoided;
