Description
Technical field
The utility model relates to the charged descaling machine of high voltage isolator dynamic/static contact.
Background technology
Can transformer station's mesohigh isolated switchgear normally operate in the contact resistance (General Requirements is about 100 micro-ohms) depending on isolation switch contact to a great extent.By surrounding environment impact (as industrial gas emission pollute, particularly chemical emission exhaust emission, salt-alkali contaminated corrosion, long oxidation corrosion etc.) etc., along with the growth of operation hours, make the corrosion gradually of isolation switch contact conductive contact surfaces, surface forms layer of oxide layer, increase to making contact resistance, under accidental conditions, contact caloric value increases, temperature raises, corrosion oxide layer is made again to increase the weight of along with temperature raises, cause contact resistance and then increase, produce contact resistance larger, heating, temperature rise is higher, corrosion is oxidized vicious circle faster.Happen occasionally in operation because of corrosion cause isolation switch contact to burn out, scorification accident so that need to change the global facility of isolating switch, cause great economic loss.In addition, be in operation as ensureing that good normal employing of isolation switch contact contact smears conductive paste on contact conductive contact surfaces.Because conductive paste contains lubricant component, at conductive paste surface laying dust rapidly after operation a period of time, along with conductive paste is air-dry gradually, isolation switch contact conductive contact surfaces forms one deck dirt, the dynamic and static contact of isolating switch effectively can not be contacted, cause heating.The isolating switch that is in disjunction state of happening occasionally in operation has just put into operation and namely contact heating problem has occurred, and just can must put into operation after the schmutzband grinding process of contact surface.
For preventing isolating switch from causing contact to burn out accident because of dirt, corrosion, adopt infrared imaging inspection device heat condition at present, stop transport according to the contact heating temp situation application isolated switchgear that exceeds standard, maintainer carries out work high above the ground process.The power failure of isolating switch dynamic and static contact both sides often needs the stoppage in transit of whole section of bus.Therefore, for arranging an isolation switch contact maintenance, needing the safety measure etc. of the clear erasure reason in loaded down with trivial details grid switching operation, manually high-altitude need spend very long power off time, not only expending huge man power and material, also have a strong impact on multiple power supply.
Summary of the invention
The utility model is the deficiency solving prior art existence, provides a kind of structure simple, easy to use, not power-off, the charged descaling machine of high voltage isolator dynamic/static contact of handling safety.
The charged descaling machine of a kind of high voltage isolator dynamic/static contact, its special character is: comprise motor, motor output shaft end is provided with screw thread, this descaling machine is also provided with more piece insulating driving rod, described insulating driving rod one end is provided with the screwed hole matched with motor output shaft screw thread, the other end is provided with the screw thread closed with this corresponding threaded holes, and described insulating driving rod is connected with motor output shaft by screw thread, and every two joint insulating driving rod are threaded connection; This descaling machine is also provided with a cleaning hairbrush, and this cleaning hairbrush is provided with the screwed hole matched with insulating driving rod screw thread, and described cleaning hairbrush and insulating driving rod are threaded connection.
Wherein a joint insulating driving rod is arranged with universal bearing, universal bearing is welded with a support outward admittedly, and the supporting leg of described support is collapsible.
The beneficial effects of the utility model are: utilize the devices such as motor, insulating driving rod and cleaning hairbrush to clear up high voltage isolator dynamic/static contact, and structure is simple, and without power-off, operating personnel also need not climb high-rise working, operate safer, faster.Insulating driving rod is established on the ground by universal bearing and support link, operating personnel only need control motor just adjustable cleaning hairbrush process position, operate more convenient; The supporting leg of support is collapsible, needs to regulate a leg length, thus regulate the height of cleaning hairbrush according to working environment.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the A-A sectional view of Fig. 1.
In figure: 1-motor, 2-insulating driving rod, 3-universal bearing, 4-support, 5-clears up hairbrush, 401-supporting leg.
Detailed description of the invention
As shown in the figure, the charged descaling machine of a kind of high voltage isolator dynamic/static contact, comprise motor 1, motor 1 output shaft end is provided with screw thread, this descaling machine is also provided with more piece insulating driving rod 2, and described insulating driving rod 2 one end is provided with the screwed hole matched with motor 1 output shaft screw thread, and the other end is provided with the screw thread closed with this corresponding threaded holes, described insulating driving rod 2 is connected with motor 1 output shaft by screw thread, and every two joint insulating driving rod 2 are threaded connection; This descaling machine is also provided with a cleaning hairbrush 5, and this cleaning hairbrush 5 is provided with the screwed hole matched with insulating driving rod 2 screw thread, and described cleaning hairbrush 5 is threaded connection with insulating driving rod 2.
Wherein a joint insulating driving rod 2 is arranged with universal bearing 3, universal bearing 3 is outer is welded with a support 4 admittedly, and the supporting leg 401 of described support 4 is collapsible.
During operation, insulating bar is first utilized to be separated by the dynamic/static contact of pre-cleaning, the Near Ground below the dynamic/static contact this descaling machine being placed on pre-cleaning.According to the height of the position adjusting pole 4 at the dynamic/static contact place of pre-cleaning and the length of insulating driving rod 2, cleaning hairbrush 5 is contacted completely with the dynamic/static contact of pre-cleaning.Switched on power by motor 1, the dynamic/static contact of starter motor 1 pair of pre-cleaning is cleared up again.
