Description
Technical field:
The present invention relates to a kind of armored mid-set metal closed switch cabinet earthing device, belong to electric power system substation equipment maintenance and repair technical field.
Background technology:
10kV armored mid-set metal closed switch cabinet is a kind of air insulation of utilizing; the converting equipments such as bus, circuit breaker, CT, PT, lightning arrester, earthed switch are integrated in to the cabinet type electric equipment in enclosure space, in operation of power networks because of its reasonable in design, protective value is good, breaking capacity is strong, dynamic thermal stability is good, interchangeability is strong, working service is convenient etc., and advantage is used widely.
But operating personnel are in equipment power failure operating process, when in armored mid-set metal closed switch cabinet cabinet, bus carries out electrical verification, ground connection, electrical verification, ground connection that neither one point can be safe and reliable.If be articulated on the interior fixed contact of switch cabinet, violated < < state net grid company electric power safety working regulation (power transformation part) > > 4.5.4 bar regulation: " after handcart is pulled out in high-tension switch cabinet, isolate the baffle plate sealing at charged position then forbid opening "; If by opening the mode of switch cabinet bus room cover plate, in switch cabinet, bus is in order to increase all roasting material contracting with heats that covered of withstand voltage level skin, joint is also sealed with pyrocondensation contact box, cause earth connection also there is no rational hitching position, and earth connection very easily comes off, bring very large potential safety hazard to operating personnel's electrical verification and maintainer's maintenance process.Simultaneously, when armored mid-set closed switch cabinet bus and corresponding device carry out the work such as high voltage test and a nuclear phase, because contact in cabinet is round design, during test, binding clip is fixing unreliable, the fail safe in the time of cannot guaranteeing equipment test and the accuracy of test data.
Summary of the invention:
The object of the invention is to overcome the deficiency of above-mentioned prior art and a kind of safe and reliable electrical verification, ground connection of bus in armored mid-set switch cabinet that can complete is provided, guaranteed the accuracy of experimental measurement data, reduced interruption duration, eliminate safe hidden trouble, improve power supply reliability, guaranteed the armored mid-set metal closed switch cabinet earthing device of maintainer's personal safety.
Order of the present invention can reach by following measure: a kind of armored mid-set metal closed switch cabinet earthing device, it comprises device body, the lower end that it is characterized in that device body is provided with shifting roller, device body connects hand crank by turnover leading screw, and hand crank connects locking box, the upper end connecting sensor of device body, transducer connects respectively moving contact, sense light, sense light joint test binding clip, test connection folder connects earth connection, ground wire connecting device body.
The present invention can produce following good effect compared with the prior art: the present invention is detachable earthing device, can meet the instructions for use of the armored mid-set closed switch cabinet of different size, rational and orderly complete bus electrical verification, ground connection, experimental measurement, step is rigorous, safe.
1,, by install transducer additional on moving contact, can, the in the situation that of equipment live, start charged warning lamp, terminating operation.
2, by the charged position of extension device, directly whether Authentication devices is charged, safe, easy and simple to handle, the consumption time is short for electroscope.
3, install earthing clamp additional, with cabinet reliable ground, fixing reliable, simple operation, making are simple, safe and reliable.
4, by installing fixedly Special test binding clip additional, contact is reliable, and test data is more accurate.
The present invention can be safely and effectively to equipment electrical verification, and finishing equipment grounding measures.This invention has solved the difficult problem that armored mid-set metal closed switch cabinet bus interruption maintenance is done electrical verification, grounding safety measure, eliminate potential safety hazard, guaranteed the accuracy of experimental measurement data, reduced interruption duration, improve company's power supply reliability, guaranteed maintainer's personal safety.
Accompanying drawing explanation:
Fig. 1 is structural representation of the present invention.
Embodiment: preferred forms of the present invention is elaborated below in conjunction with accompanying drawing:
Embodiment: a kind of armored mid-set metal closed switch cabinet earthing device (referring to Fig. 1), it comprises device body 5, the lower end of device body 5 is provided with shifting roller 6, the bottom of device body 5 connects hand crank 1 by turnover leading screw 7, hand crank 1 connects locking box 11, the upper end connecting sensor 3 of device body 5, transducer 3 connects respectively moving contact 2, sense light 4; Sense light 4 joint test binding clip 9 test connection folders 9 connect earth connection 8, and earth connection 8 is connected with the lower end of device body 5.
After equipment and bus power failure finish, operations staff places grounding device of switch cabinet in switch cubicle, by locking box 11 and switch cubicle locking, then by shaking hand crank 1, locking box 11 is motionless at that time, turnover leading screw 7 and the interlock of switch cabinet inner nut, drive shifting roller 16 activities by right rotation hand crank 1, by earthing device body 5 shake into.Shake into time, when moving contact 2 closes in cabinet fixed contact, if fixed contact is charged, transducer 3 is induction charging, by the glittering warning of sense light 4, shows in cabinet chargedly, earthing device must not enter.If transducer 3 is failure to actuate, sense light 4 does not work, and can continue to shake into earthing device, shake into after, utilize electroscope electrical verification, really, after no-voltage, by earth connection 8 three-phase shortcircuits, ground connection draw-in groove 10 blocks with switch cabinet main ground connection, connects reliably, electrical verification, ground connection have been worked.If need do high voltage test to bus in cabinet, earth connection 8 to be removed, testing equipment presss from both sides 9 by test connection and connects, and can complete correlation test work, guarantees the accuracy of measurement data.
