Abstract
The utility model relates to a high voltage switch insulation measuring device comprising a three-phase double-throw disconnecting switch (10). The disconnector (11) is connected with a three-phase contact (21) of a high-voltage switch earth disconnector (20), which is connected with the three-phase contact (21) through an insulator (23). One group static contact (12) of the two groups of static groups (12) and (13) of the disconnecting switch (10) is grounding. The double-throw disconnecting switch (10)'s operating board (14) is provided with a conductive contact (16) whose three backs are connected with the static contact (13) separately. The measuring device can be applied to the shell of high voltage switch (or switch cabinet) directly, and able to make test conveniently and efficiently without dismantling high-voltage switch. The combination with the earth disconnector of the high-voltage switch avoids the possibility of wrong operations in working positions.
Description
Technical field the utility model relates to measurement mechanism, particularly is used for the device of the high-voltage switch gear insulation measurement of large-scale power facility.
Background technology is present, and ground cutter that electrical equipment is used and insulation measurement device are complete disjunct two separate components, during overhaul of the equipments by " cutter operating handle " close cutter, when needing to measure insulation, at first to and shake the maintenance position, take off secondary plug, switch be hauled out with dolly with the switch power failure, and then measuring switch is served with dolly, and shake the working position, electrical verification is also carried out insulation measurement to motor, after having surveyed, measuring switch is hauled out, more former switch is resetted.Operate loaded down with trivial details especially, the low and wasting manpower and material resources of efficient, moreover frequent dismounting has also directly influenced the reliability and the serviceable life of equipment.Also have a kind of original measuring method, open the switch cubicle door exactly, directly go to measure to the three-phase contact of motor, this mode is abnormally dangerous, has brought direct threat for operating personnel's personal safety.
Summary of the invention the utility model has designed a kind of switch measurement mechanism, connects on equipment under test, solves complex operation, inefficient technical matters in the prior art.Further this switch is connected on the ground cutter of high-voltage switch gear, solves technical problem of poor safety in the prior art.
The scheme that the utility model solves the problems of the technologies described above is as follows: this high-voltage switch gear insulation measurement device comprises three-phase double-throw disconnecting link switch, the disconnecting link of this disconnecting link switch connects the three-phase contact of high-voltage switch gear ground cutter respectively by line, be connected one group of static contact ground connection in two groups of static contacts of disconnecting link switch by insulator between described ground cutter and the three-phase contact.When needs are measured insulation, high-voltage switch gear ground cutter is closed on the contact of equipment under test, three-phase double-throw disconnecting link switch closes on one group of static contact of non-ground connection, just can reflect the insulation values of equipment truly by one group of static contact insulation over the ground of the non-ground connection of megger measurement disconnecting link switch.
The designed measurement mechanism of the utility model can directly be contained on the shell (or switch cabinet) of high-voltage switch gear, just can directly measure without the dismounting high-voltage switch gear, it is convenient to measure, the efficient height, combine with the ground cutter of high-voltage switch gear, avoided the possibility of this maloperation of measuring in the working position, safe and reliable.
Description of drawings
Fig. 1 is the schematic perspective view of the utility model high-voltage switch gear insulation measurement device.
Fig. 2 is a principle of work synoptic diagram of the present utility model.
Embodiment accompanying drawings specific embodiment of the utility model.
By finding out among Fig. 1 and Fig. 2, this high-voltage switch gear insulation measurement device comprises three-phase double-throw disconnecting link switch 10, the disconnecting link 11 of this disconnecting link switch 10 connects the three-phase contact 21 of high-voltage switch gear ground cutter 20 respectively by line 30, be connected one group of static contact 12 ground connection in two groups of static contacts 12 of disconnecting link switch 10 and 13 between described ground cutter 20 and the three-phase contact 21 by insulator 23.The designed measurement mechanism of the utility model can also use by local cutter, when needing local cutter to use, at first equipment is had a power failure, switch shakes test or maintenance position, disconnecting link switch 10 closes in " cutter " shelves---and be that disconnecting link 11 is connected with static contact 12, after the detection equipment under test was not charged, the ground cutter 20 of the high-voltage switch gear that closes had been realized the purpose to equipment under test ground connection.When needs are measured insulation, by ground cutter operating mechanism 22 high-voltage switch gear ground cutter 20 is closed on the contact of equipment under test, three-phase double-throw disconnecting link switch 10 closes on one group of static contact 13 of non-ground connection, and the insulation of measuring 17 of one group of static contact 13 of disconnecting link switch 10 non-ground connection and the earthing contacts on the guidance panel 14 by megger just can reflect the insulation values of equipment truly.Then disconnecting link 11 is closed on static contact 12, bleed off the surplus electricity of equipment under test, carry out next step surveying work.
By among Fig. 1 as can be known, duty for correct indication disconnecting link 11, described disconnecting link switch 10 also includes guidance panel 14, the joystick of disconnecting link 11 is convexly equipped with on the surface of this guidance panel 14, and this guidance panel 14 is provided with two corresponding disconnecting links 11 and closes in the Warning Mark 15 of two groups of static contacts 12 and 13 positions.
By among Fig. 1 and Fig. 2 as can be known, described disconnecting link switch 10 guidance panels 14 are provided with three conductive contacts 16, the back side of these three conductive contacts 16 connects three contacts of another group static contacts 13 of disconnecting link switch 10 respectively.When needing to measure insulation,, increase safety coefficient, also made things convenient for measurement as long as the insulation values between these three conductive contacts 16 of measurement and the earthing contact 17 is not used the back side of guidance panel 14 and removed to survey static contact 13.
By among Fig. 2 as can be known, also be provided with earthing contact 17 on described disconnecting link switch 10 guidance panels 14, these earthing contact 17 ground connection can avoid guidance panel 14 itself charged like this, improve security.
By among Fig. 1 and Fig. 2 as can be known, on described disconnecting link switch 10 guidance panels 14 in two Warning Marks 15 corresponding indication disconnecting link 11 close in the Warning Mark of static contact 12 positions and be electrically connected with static contact 12, can on guidance panel 14, directly measure the ground state of static contact 12 like this, be convenient for measuring.
