Technical field
The utility model relates to a kind of servicing unit for gas insulated metal enclosed swit chgear withstand voltage test, specifically for gas insulated metal enclosed swit chgear when the withstand voltage test, the detachable connecting device of gas insulated metal enclosed swit chgear and voltage transformer (VT), lightning arrester.
Background technology
In electric equipment, gas insulated metal enclosed swit chgear is called for short again GIS, and voltage transformer (VT) is called for short PT, and lightning arrester is called for short LA.According to GB/T 16927.1-1997 < < high-voltage test techniques first: ordinary test requires > >, DL/T 617-1997 < < Cubicle Gas-Insulated Switchgear technical conditions > >, the on-the-spot withstand voltage and Insulation Test guide rule > > regulation of the on-the-spot commissioning test rules > > of DL/T 618-1997 < < Cubicle Gas-Insulated Switchgear and DL/T 555-2004 < < Cubicle Gas-Insulated Switchgear, GIS device context installs need carry out withstand voltage test, but be connected to the voltage transformer (VT) unit on GIS equipment, quarantine measures should be taked in lightning arrester unit, avoid applying trial voltage.
Current common way has: one, GIS and voltage transformer (VT), lightning arrester junction install disconnector additional.Two, take first to carry out the withstand voltage scheme that PT, LA are installed again of GIS.
Method one needs the disconnector that assembly structure is complicated, cost is expensive, increase a whole set of control loop, and this disconnector only need to disconnect PT when GIS equipment is withstand voltage, LA is used during unit, and practical function does not mate with paying a price.
Method two is not first installed PT, LA, but adopts the mode that installs sealing cylinder additional to keep for the interface of PT, LA to shield, and opens air chamber again PT, LA are installed after the scene for the treatment of is withstand voltage.The method has only increased sealing cylinder, and cost increases few, but need scene to open equipment air chamber, carries out bus docking, and shortcoming comprises: 1. need the air chamber opened larger, open a large amount of SF6 gas of a less important waste.2. the on-the-spot purification condition that does not possess manufacturing plant's requirement, easily causes insulation fault during docking.3. general PT, LA equipment are all positioned at bus below, and the later stage is inconvenient to carry out lifting operation while installing.4. because other equipment are all in place, then when PT, LA equipment are installed, just require high merging precision.
Summary of the invention
The utility model provides a kind of simple and reasonable for structure, cost-saving, easy and simple to handle in order to overcome above-mentioned defect, avoids later stage docking, withstand voltage test detachable connecting device that can the reduction of erection time.
The technical solution adopted in the utility model is: a kind of detachable connecting device for gas insulated metal enclosed swit chgear withstand voltage test, it is characterized in that: comprise housing, movable contact block, fixed contact pedestal, conducting rod and disc insulator, housing is three way type structure, in upper shed place of housing, disc insulator is set, at housing lower opening, be provided with lower disc insulator, side mouth place at housing is provided with end cap, in housing, the bottom of upper disc insulator arranges movable contact block, top at lower disc insulator is provided with fixed contact pedestal, moving, the outside of fixed contact pedestal is provided with radome, conducting rod can be inserted into movable contact block inside and be flexibly connected with movable contact block by bearing pin.
In the utility model, on housing, be provided with adsorbent and pull out mouth.
The utility model has designed the housing of threeway shape, and form independent little air chamber structure, in housing, be provided with movable contact block and fixed contact pedestal, between dynamic and static touch base, can connect or disconnect by conducting rod, during off-state, do not need to dismantle PT, LA, just can make On-Site Testing, after having tested, SF6 gas in housing is recyclable, then by conducting rod, movable contact block is connected with fixed contact pedestal, easy to operate, the complicated procedures of forming of having avoided later stage docking PT, LA, shortens installation period greatly.The utility model is simple in structure, cost-saving, has improved work efficiency.
Accompanying drawing explanation
Fig. 1 is off-state schematic diagram of the present utility model.
Fig. 2 is connection status schematic diagram of the present utility model.
Fig. 3 is the utility model installation site schematic diagram.
Embodiment
Now by reference to the accompanying drawings the utility model is further described, Fig. 1 is a kind of embodiment of the present utility model, comprise housing 1, movable contact block 2, fixed contact pedestal 3, conducting rod 4 and disc insulator 5, housing 1 is three way type structure, in upper shed place of housing 1, disc insulator 5 is set, at housing 1 lower opening, be provided with lower disc insulator 10, side mouth place at housing 1 is provided with end cap 6, in housing 1, the bottom of upper disc insulator 5 arranges movable contact block 2, on the top of lower disc insulator 10, be provided with fixed contact pedestal 3, moving, the outside of fixed contact pedestal 3 is provided with radome 9, conducting rod 4 can be inserted into the inner bearing pin 7 that also passes through of movable contact block 2 and be flexibly connected with movable contact block 2.In the present embodiment, on the wall in housing 1, be provided with adsorbent 8, for adsorbing the moisture in housing 1, guarantee well-equipped electric property.
The utility model is arranged between bus assembling 11 and voltage transformer (VT) 12 or lightning arrester, see Fig. 3, when equipment need to be done withstand voltage test, conducting rod 4 is inserted into the inside of movable contact block 2 completely, and by bearing pin 7, itself and movable contact block 2 are fixed, see Fig. 1, prevent that conducting rod 4 from leaning out spherical shield cover 9 under Action of Gravity Field, shorten fracture apart from guiding discharge.Now, between dynamic and static contact base 3, disconnect and not connecting, and under radome 9 effects, its fracture is two close spherical states, electric field is even, can tolerate power frequency 740kV 1min, impacts the high pressure of 1675kV, therefore, do not need to disassemble PT, LA, can complete examination withstand voltage test.When test completes, only need to reclaim the SF6 gas in housing 1, open end cap 6, bearing pin 7 is extracted, then make conducting rod 4 one end insert movable contact block 2, the other end inserts fixed contact pedestal 3, re-uses bearing pin 7 conducting rod 4 is connected with movable contact block 2, prevent that conducting rod 4 from exiting fixed contact pedestal 3 under electrodynamic effect, sees Fig. 2.
The utlity model has following advantage:
1. simple in structure, cost-saving, cost deficiency installs 1/5 of disconnector additional.
2. the conversion of disconnection or connection status is convenient, fast, affected by on-the-spot installation environment little.
3. avoid later stage docking PT, LA, greatly shortened installation period.
4. can install the transitional shell of suitable length additional according to other equipment and PT, LA relative position, convenient expansion, meets multi-state needs.
Can derive and be applied to the situation that all engineering sites need to be manufactured fracture, range of application is wide.
