Description
Technical field
The utility model relates to power transmission and transformation field breaker in middle auxiliary equipment, is specially deciliter position indicator of the isolation of high pressure GIS device, earthed switch.
Background technology
High pressure GIS device plays vital effect in operation of power networks, and a deciliter instruction for its isolating switch at present all adopts word to indicate, and text space is excessive, and displacement pointing accuracy is low, and whether divide-shut brake puts in place accurately can not to reflect isolating switch; Alternate transmission adopts rotation axis transmission in addition, and need unnecessary rotation axis transmission during operation, on operating mechanism, only there is a deciliter position instruction, but the isolation of each phase, earthed switch are difficult to install a deciliter position instruction additional, once transmission link occurs connecting timeliness or unreliable, can cause isolating, earthed switch is deciliter not in place or there is the potential safety hazard of phase-deficient operation.
Summary of the invention
For solving the technical problem of above-mentioned existence, the utility model spy provides a kind of power transmission shaft that is applicable to and rotates the isolation, the earthed switch deciliter position indicator that turn the high pressure GIS device of transmission more, this device and the coaxial transmission of trigger pivot axis, pointing accuracy is high, stable operation safety.
For achieving the above object, technical solution adopted in the utility model is:
A kind of isolation of high pressure GIS device, earthed switch deciliter position indicator, it comprises protected enclosure, bevel gear I is provided with in protected enclosure, bevel gear II, bevel gear I arranges on the rotating shaft, two bevel gears can engage by perpendicular contact, rotation axis front is fixedly installed drive lead screw, drive lead screw and rotation axis co-rotation, drive lead screw is equipped with slide block to be connected with transmission wire rod thread, protected enclosure internal fixtion is provided with locating shaft, locating shaft is parallel with drive lead screw, slide block is slidably connected with locating shaft simultaneously, slide block end is provided with pointer, protected enclosure is provided with transparency window, Pointing sign board is provided with bottom transparency window, pointer arrow points Pointing sign board.
Pointing sign board is provided with opening and closing point instruction coordinate, move between label folding point through the visible pointer of transparency window, when two bevel gears contact completely time, the chalaza of pointer instruction on Pointing sign board, when bevel gear separates completely, pointer instruction is in battle.
The beneficial effects of the utility model are: pointer is arranged on slide block, slide block is driven by the drive lead screw coaxial with rotation axis, the direction that is in line by old-fashioned rotation transmission, conversion is moved, position pointing accuracy is high, the other end of slide block is provided with locating shaft guiding, and ensure that slide block moves steadily, safe and reliable, this device is arranged in the transmission device of high pressure GIS isolation, earthed switch, can realize that each is isolated, independent deciliter position instruction of earthed switch, can allow the equipment security of operation hidden danger that the transmission of maintainer's Timeliness coverage causes.

Fig. 2 is the utility model internal structure schematic diagram;
Fig. 3 is Fig. 2 plan structure schematic diagram.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in detail: a kind of isolation of high pressure GIS device, earthed switch deciliter position indicator, it comprises protected enclosure 1, bevel gear I 2 is provided with in case, bevel gear II 3, bevel gear I 2 is arranged on rotation axis 4, two bevel gears can engage by perpendicular contact, rotation axis 4 front is fixedly installed drive lead screw 5, drive lead screw 5 and rotation axis 4 co-rotation, drive lead screw 5 is equipped with slide block 6 to be slidably connected with transmission screw mandrel 5 screw thread, protected enclosure 1 internal fixtion is provided with locating shaft 7, locating shaft 7 is parallel with drive lead screw 5, slide block 6 is slidably connected with locating shaft 7 simultaneously, slide block 6 end is provided with pointer 8, protected enclosure 1 is provided with transparency window, Pointing sign board 9 is provided with bottom transparency window, pointer 8 arrow points Pointing sign board 9.
Pointing sign board 9 is provided with opening and closing point instruction coordinate, move between label folding point through the visible pointer 8 of transparency window, when two bevel gears contact completely time, pointer 8 indicates the chalaza on Pointing sign board, when two bevel gears separate completely, pointer 8 indicated in battle.
Drive lead screw 5 adopts feed screw nut's structure, can directly isolation, on earthed switch power transmission shaft extending shaft machining screw as drive lead screw, slide block 6 nut adopts the material manufacture that the coefficient of frictions such as copper, zinc-containing alloy or plastics are lower, and the redness that pointer brush is eye-catching, is used to indicate position.
When isolating switch to carry out point, closing operation time drive lead screw clockwise or rotate counterclockwise, thus drive the slide block coordinated with screw mandrel to realize rectilinear motion.Pointer is linearly moved to deciliter band of position of label " I " or " 0 " under the drive of slide block, indicates the service position that isolating switch is now residing.Have one section to be coated with the instruction of coloured scope respectively in the top of " I " open region and " 0 " chalaza, pointer finally stops in this segment limit and just represents isolating switch and to close a floodgate or separating brake puts in place.This device is arranged on respectively on each isolated, earthed switch transmission device, just can accurately indicates the divide-shut brake location status of each phase.
