Abstract
The utility model discloses a novel transformer ratproof cover which comprises a protecting cover body and a line blocking groove arranged together with the protecting cover body in an integral way, wherein the axisymmetric positions on the outer circumference of the protecting cover body are provided with two grooves. The utility model also relates to a replacing tool of the transformer ratproof cover, comprising an insulating long rod, one end of which is provided with two straight claws and a pressing plate, wherein the two straight claws are matched with the two grooves arranged at the axisymmetric positions on the protecting cover body. The utility model leads the traditional ratproof cover replacing technique which is transformer high-voltage side main rod ascending rod to be improved to be the material selecting requirements of the replacing tool of transformer low-voltage side auxiliary rod ascending rod, and the whole body is made of insulating material. As the two straight claws and the pressing plate on the replacing tool respectively correspond to the two grooves on the protecting cover body and a cover top thereof, the requirement of replacing the transformer ratproof cover in an electrified way can be met under the action of the three points on the protecting cover body.
Description
Technical field
The utility model belongs to transformer auxiliary equipment technical field, particularly a kind of novel transformer Antimouse hood and replacing instrument.
Background technology
Antimouse hood is a kind of a kind of auxiliary equipment that prevents phase fault or ground connection that is arranged on the transformer high-voltage post, its essence is to expose aerial high-pressure column and go between and build with insulating lid, after avoiding some toys or branch to run into, cause phase fault or earth fault, cause dangerous accident.Since Antimouse hood be the time outdoor, wind blows Exposure to Sunlight, aging speed is very fast, under the premise that security is guaranteed, with regard to must regularly checking outdoor a large amount of Antimouse hood, some Antimouse hoods that may influence safety in production is more changed.
The tradition Antimouse hood comprises cover body and cable clamping interface two parts, cover body is provided with the guard shield longitudinal opening that is used for threading, cable clamping interface is the swallow-tail form notch, its design feature has determined personnel must manually break the longitudinal opening on cable clamping interface and the outer shield wall into two with one's hands, Antimouse hood could be loaded onto high-pressure column, thereby require transformer to have a power failure.And be to climb up the transformer high-voltage side to change, under situation about not having a power failure, the staff can not finish above-mentioned work under the prerequisite that guarantees personal safety.Antimouse hood is changed the time spent situation and is added up, and find that average out to changed one group of Antimouse hood in 15～20 minutes, and it is more frequent to change number of times, with higher level request and user's demand certain gap is arranged.
Some new transformer rat guards are arranged, on circumference relative on the guard shield body with cable clamping interface, be set up in parallel two perforation, and with two straight pawls and a top board that adapts with two perforation, transformer rat guard is carried out charged for replacement, shortened the operation time spent of changing Antimouse hood greatly, minimizing transformer frequency of power cut and time have been realized, but a problem that obviously exists is, the structure of this a kind of Antimouse hood is more complicated also, enough not simple, and on technology, have unmanageable characteristics.
The utility model content
The utility model provides a kind of structure simpler novel transformer Antimouse hood and the replacing instrument that does not need to have a power failure and just can change.
A kind of novel transformer Antimouse hood, it comprises guard shield body and the cable clamping interface that is wholely set with the guard shield body, on the excircle of described guard shield body, two grooves is set on the axisymmetric position.
A kind of instrument of changing transformer rat guard, comprise an insulation stock, one end of described insulation stock is provided with two straight pawls and a pressing plate, two grooves that are provided with on the axisymmetric position on described two straight pawls and the guard shield body match, described pressing plate be arranged on described two straight pawls above, cover top and groove apart from consistent on the spacing of pressing plate and two straight pawls and the guard shield body.
Because the utility model is changed tradition the technology of Antimouse hood and is stepped on bar by transformer high-voltage side mobile jib, improve to pay bar by step down side and step on bar replacing instrument selection requirement, entire body adopts the insulation material.By two straight pawls and the pressing plate on the replacing instrument, respectively the requirement of the transformer rat guard of charged for replacement by the active force of three points to the guard shield body, has been satisfied in cover top on two grooves on the corresponding guard shield body and the guard shield body.Realized changing under the charged situation intended purposes of distribution transformer Antimouse hood, and changing efficient significantly improves before than technological transformation, shorten the operation time spent of changing Antimouse hood greatly, realized minimizing transformer frequency of power cut and time, strengthened the gratifying results of mains supply reliability.
Description of drawings:
Below in conjunction with accompanying drawing the utility model is described further:
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the structural representation that the utility model is changed instrument.
Embodiment
As shown in Figure 1, a kind of transformer rat guard, it comprises guard shield body 1 and the cable clamping interface 2 that is wholely set with guard shield body 1, on the excircle of described guard shield body 1, two grooves 3 is set on the axisymmetric position.
A kind of instrument of changing transformer rat guard, comprise an insulation stock 6, one end of described insulation stock 6 is provided with two straight pawls 4 and a pressing plate 5, two grooves 3 that are provided with on the axisymmetric position on described two straight pawls 4 and the guard shield body 1 match, described pressing plate 5 be arranged on described two straight pawls 4 above, cover top and groove 3 apart from consistent on the spacing of pressing plate 5 and two straight pawls 4 and the guard shield body 1.
Because the utility model is changed tradition the technology of Antimouse hood and is stepped on bar by transformer high-voltage side mobile jib, improve to pay bar by step down side and step on bar replacing instrument selection requirement, entire body adopts the insulation material.By two straight pawls and the pressing plate on the replacing instrument, respectively the requirement of the transformer rat guard of charged for replacement by the active force of three points to the guard shield body, has been satisfied in cover top on two grooves on the corresponding guard shield body and the guard shield body.Realized changing under the charged situation intended purposes of distribution transformer Antimouse hood, and changing efficient significantly improves before than technological transformation, shorten the operation time spent of changing Antimouse hood greatly, realized minimizing transformer frequency of power cut and time, strengthened the gratifying results of mains supply reliability.
