Description
Technical field
The utility model relates to a kind of pressure test frock that detects insulated tension pole in the high-tension switch gear.
Background technology
Cubicle Gas-Insulated Switchgear is called for short GIS, and insulated tension pole is the vitals that this device interrupt road device cut-offs.It is the force transmission of hydraulic control mechanism all moving components in the arc-chutes, i.e. the power effect of transmitting.The design feature of insulated tension pole is carefully to grow, and mainly bears stretching, squeezing action power under the normal operating conditions.During combined floodgate, insulated tension pole does not receive the voltage effect, but under the gate-dividing state, higher superpotential is born at its two ends, therefore is necessary it is carried out withstand voltage test, so that find the self-defect of insulated tension pole, guarantees normally cut-offfing of arc-chutes.The pressure test frock that does not also have the special detection insulated tension pole in the market; Traditional detection mode is that range estimation or insulated tension pole is installed in the old isolating switch tank body is then tested through being connected with the sleeve pipe assembling; And can only test an insulated tension pole at every turn, detecting reliability is poor, efficient is low.
Summary of the invention
The utility model provides a kind of detecting reliability high in order to overcome above-mentioned defective, can detect the withstand voltage frock of a plurality of insulated tension poles simultaneously.
The technical scheme that the utility model adopts is: a kind of withstand voltage frock of insulated tension pole; Comprise the assembling of tank body and sleeve pipe, the both sides of tank body are provided with side plate, and the top of tank body is provided with the mouth of dialling that can be connected with the sleeve pipe assembling; The sleeve pipe assembling is installed in the tank body top through dialling mouth; Also comprise two dollies and two radomes, a dolly top connects a radome, and its outside of described radome is the round barrel shape cover body; Distributed and arranged has the groove that can insert insulated tension pole on its side; The side of radome is that rounding off is connected with outside cover body, and two dollies and radome are between left and right at a distance from setting, and two sides of radome band groove are oppositely arranged; The dolly its underpart that is arranged on the left side is connected with the tank body conduction through connecting copper bar, and the conducting rod in the radome on its top of dolly on the right of being arranged on and the assembling of said sleeve pipe is for flexibly connecting
.
Radome side distributed and arranged has 5-9 the groove that can insert insulated tension pole.
The utility model respectively is provided with a radome through two dollies are set in tank interior on each dolly, the side of radome is provided with the groove that can insert insulated tension pole; Two dollies are between left and right at a distance from being provided with; During use, insert respectively in the groove of two radomes at the two ends of insulated tension pole, and the radome on the right is connected with the interior conducting rod of sleeve pipe assembling of tank body top; The dolly of the radome below on the left side is connected with the tank body conduction through conducting copper; Grading ring with the assembling of hi-line and sleeve pipe is connected like this, charges into SF6 gas after tank body being sealed again, and applies high voltage then and detects and just can.The utlity model has simple in structurely, cost is low, and detecting reliability is high, can detect a plurality of insulated tension poles simultaneously through the groove of radome, increases work efficiency.
Description of drawings
Fig. 1 is the synoptic diagram of the utility model.
Embodiment
Combine accompanying drawing that the utility model is further described, Fig. 1 is a kind of embodiment of the utility model at present, comprises tank body 1, sleeve pipe 2, two dollies 5 of assembling and two radomes 6.The both sides of tank body 1 are provided with side plate, and side plate can seal tank body 1.The top of tank body 1 be provided with can with sleeve pipe assemble 2 be connected dial mouthful, sleeve pipe assembling 2 is installed in tank body 1 top through dialling mouth.Dolly 5 tops connect a radome 6, generally connect with bolt.Described radome 6 its outsides are the round barrel shape cover body; Distributed and arranged has the groove that can insert insulated tension pole 4 on its side; The side of radome 6 is that rounding off is connected with outside cover body; Usually radome 6 does not all have wedge angle, and the connection between each face of the outside cover body and the groove of sidepiece is rounding off.Be between left and right at a distance from being provided with between the radome 6 on two dollies 5 and top thereof, promptly the radome 6 on two dollies 5 and top is split-type structural when not working.Those two sides of said radome 6 band grooves are oppositely arranged, and can conveniently insert 4, two radomes of insulated tension pole 6 like this and connect through the insulated tension pole 4 that inserts.Dolly 5 its underparts that are arranged on the left side are connected with tank body 1 conduction through connecting copper bar, and the conducting rod 3 in the radome 6 on dolly 5 its tops on the right of being arranged on and the said sleeve pipe assembling 2 is flexible connection
.The radome 6 side distributed and arranged of the utility model have 5-9 the groove that can insert insulated tension pole 4, and present embodiment is provided with 7 grooves, can detect 7 insulated tension poles 4 simultaneously.
During use, the two ends difference level of insulated tension pole 4 is inserted in the groove of two radomes 6, with bolt that radome 6 and insulated tension pole 4 is fastening.The sleeve pipe assembling 2 and the mouth that pulls out of tank body 1 are fixed, and the radome 6 on the right is connected with the conducting rod 3 that sleeve pipe assembles in 2, the grading ring of hi-line with sleeve pipe assembling 2 is connected again.Then conducting copper is reliably conducted electricity with tank body 1 and be connected; Biside plate is installed is carried out sealed shell of tank 1; Fill the SF6 gas of 0.5MPa to tank body 1 inside, apply 740kV voltage then, and keep 1min; In the pressure process discharge off sound and open jar after observe insulated tension pole 4 and do not have and damage, explain that just insulated tension pole 4 is qualified.
The utlity model has simple in structure, cost is low, detecting reliability is high, but the characteristics of batch detection insulated tension pole.
