Description
Technical field:
The utility model relates to a kind of armored mid-set metal closed switch cabinet earthing device, belongs to electric power system substation equipment maintenance and repair technical field.
Background technology:
10kV armored mid-set metal closed switch cabinet is that one utilizes air insulation; the converting equipments such as bus, circuit breaker, CT, PT, lightning arrester, earthed switch are integrated in the cabinet type electric equipment in enclosure space, in operation of power networks because of its reasonable in design, the advantage such as protective value is good, breaking capacity is strong, dynamic thermal stability is good, interchangeability is strong, working service is convenient and being used widely.
But operating personnel are in equipment power failure operation process, to when in armored mid-set metal closed switch cabinet cabinet, bus carries out electrical verification, ground connection, the electrical verification that neither one point can be safe and reliable, ground connection.If be articulated in switch cabinet on fixed contact, then violate " State Grid Corp.'s electric power safety working regulation (power transformation part) " 4.5.4 article regulation: " in high-tension switch cabinet handcart pull-out after, isolate charged position baffle plate close after forbid open "; If by the mode opening switch cabinet bus room cover plate, in switch cabinet, in order to increase, withstand voltage level skin is all roasting has covered material contracting with heat to bus, joint is also closed with pyrocondensation contact box, earth connection is caused also not have 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 fix unreliable, fail safe when cannot guarantee equipment test and the accuracy of test data.
Utility model content:
The purpose of this utility model is to overcome the deficiency of above-mentioned prior art and provides a kind of and can complete electrical verification that in armored mid-set switch cabinet, bus is safe and reliable, ground connection, ensure that the accuracy of test measurement data, decrease interruption duration, eliminate safe hidden trouble, improve power supply reliability, ensure that the armored mid-set metal closed switch cabinet earthing device of the personal safety of maintainer.
Order of the present utility model can be reached by following measure: a kind of armored mid-set metal closed switch cabinet earthing device, it comprises device body, it is characterized in that the lower end of 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 moving contact, sense light respectively, sense light joint test binding clip, test connection folder connects earth connection, ground wire connecting device body.
The utility model can produce following good effect compared with the prior art: the utility model is detachable earthing device, the instructions for use of the armored mid-set closed switch cabinet of different size can be met, rational and orderly complete bus electrical verification, ground connection, test measure, step is rigorous, and fail safe is high.
1, by installing transducer additional on moving contact, when equipment live, charged warning lamp can be started, terminating operation.
2, by the charged position of extension device, electroscope can directly whether Authentication devices be charged, and fail safe is high, easy and simple to handle, consumes time is short.
3, install earthing clamp additional, with cabinet reliable ground, fixing reliable, simple operation, making are simple, safe and reliable.
4, by installing fixing Special test binding clip additional, contact is reliable, and test data is more accurate.
The utility model can safely and effectively to equipment electrical verification, and finishing equipment grounding measures.This utility model solves the difficult problem that armored mid-set metal closed switch cabinet bus interruption maintenance does electrical verification, grounding safety measure, eliminate potential safety hazard, ensure that the accuracy of test measurement data, decrease interruption duration, improve company's power supply reliability, ensure that the personal safety of maintainer.
Accompanying drawing illustrates:
Fig. 1 is structural representation of the present utility model.
Embodiment: preferred forms of the present utility model is elaborated below in conjunction with accompanying drawing:
Embodiment: a kind of armored mid-set metal closed switch cabinet earthing device (see 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 moving contact 2, sense light 4 respectively; Sense light 4 joint test binding clip 9 test connection folder 9 connects earth connection 8, and earth connection 8 is connected with the lower end of device body 5.
After equipment and bus power failure terminate, grounding device of switch cabinet is placed in switch cubicle by operations staff, locking box 11 and switch cubicle are locked, then by shake hand crank 1, locking box 11 is motionless at that time, turnover leading screw 7 be engaged with switch cabinet inner nut, by right rotation hand crank 1 drive shifting roller 16 activity, earthing device body 5 is shaken into.Shake into time, when moving contact 2 closes on fixed contact in cabinet, if fixed contact is charged, transducer 3 i.e. induction charging, by the glittering warning of sense light 4, show in cabinet charged, 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, after true no-voltage, by earth connection 8 three-phase shortcircuit, ground connection draw-in groove 10 and switch cabinet main ground connection are blocked, and connect reliable, electrical verification, ground connection have worked.If need do high voltage test to bus in cabinet, removed by earth connection 8, testing equipment is connected by test connection folder 9, can complete correlation test work, guarantee the accuracy of measurement data.
