Description
Technical Field
The utility model belongs to the technical field of vacuum switch energy storage spring installs and removes equipment, a vacuum switch energy storage spring installs and removes instrument is related to.
Background
In an electric power system, the 35kV vacuum switch is maintained and overhauled, so that the defects in the internal electrical or mechanical aspects of equipment can be found in time, the detected defective equipment is overhauled and eliminated, and a serious person replaces the defective equipment to avoid faults in the operation of the equipment, so that the maintenance of the equipment is an important measure for ensuring the safe operation of the equipment, and the overhaul of the equipment is an important method for ensuring the stable operation of the equipment.
When the 35kV vacuum switch is maintained and overhauled, the non-tested equipment is generally required to be repaired, dismantled and replaced, so that the following problems are faced:
1. removal of springs
In the maintenance and overhaul work of the 35kV vacuum switch, when equipment in the 35kV vacuum switch is dismounted and replaced, most of the energy storage springs in the vacuum switch are firstly dismounted, and then faults in the vacuum switch are processed.
2. Spring recovery
After the fault of the 35kV vacuum switch is eliminated, the spring needs to be recovered, but the elastic potential energy of the spring is huge, so that huge troubles can be brought to maintenance personnel, huge potential safety hazards exist, and the vacuum switch can also have serious potential safety hazards.
Disclosure of Invention
The to-be-solved technical problem of the utility model is: the utility model provides a vacuum switch energy storage spring installs and removes instrument to solve the problem that exists among the prior art.
The utility model discloses the technical scheme who takes does: the utility model provides a vacuum switch energy storage spring installs and removes instrument, includes that double-end screw and two open the semicircle ring, and the double-end screw upper and lower both ends reverse spiral connection respectively have two to open the semicircle ring, and two open the semicircle ring outside and be provided with two draw-in grooves of symmetry, and the connection plate that energy storage spring both ends are connected can be gone into to two draw-in grooves.
Preferably, the back surfaces of the two opened semicircular rings are provided with screw sleeves.
Preferably, the double-thread screw has a rotating portion with a hexagonal cross section provided at a middle portion thereof.
The utility model has the advantages that: compared with the prior art, the utility model discloses a rotatory double-end screw of spanner realizes that energy storage spring both ends open and carry out the off-load, be convenient for demolish of energy storage spring, thereby realize the processing or the maintenance of trouble in the circuit breaker, the energy storage spring of the open state of direct mount after the maintenance is accomplished, reverse double-end screw carries out the release after the installation is accomplished, the operating safety is high, can solve traditional length consuming time, prevent that machinery from hindering people's potential safety hazard, the security of field test has been realized, the accuracy, the reliability, the convenience, staff's operation risk has been reduced, improve the operation work efficiency, the reliability of electric wire netting operation is improved.

Fig. 1 is a schematic structural diagram of the present invention;
fig. 2 is a schematic top view of the open semicircular ring structure of the present invention;
fig. 3 is a schematic view of the installation structure of the present invention.
Detailed Description
The present invention will be further described with reference to the accompanying drawings and specific embodiments.
Example 1: as shown in fig. 1-2, a vacuum switch energy storage spring mounting and dismounting tool comprises a double-end screw 1 and two expansion semicircular rings 2, wherein the upper end and the lower end of the double-end screw 1 are respectively and reversely spirally connected with the two expansion semicircular rings 2, two symmetrical clamping grooves 3 are arranged on the outer sides of the two expansion semicircular rings 2, the two clamping grooves 3 can be clamped into connecting plates 5 connected with the two ends of an energy storage spring 4, the clamping grooves play a role in preventing rotation, the operation is safer, and the energy storage spring is more stable in expansion.
Preferably, the back surfaces of the two open semicircular rings 2 are provided with screw sleeves 6, and the rotation directions of the two screw sleeves are opposite.
Preferably, the middle part of the double-end screw 1 is provided with a rotating part 7 with a hexagonal cross section, and the rotating part is convenient to rotate by adopting an adjustable wrench.
The utility model has the advantages of as follows:
1. safety benefits
From the analysis of the test condition at the present stage, the influence of low man-machine work efficiency, high operation risk and long time consumption brought by field operation is avoided by adopting a tool which can be applied to the portable disassembly of the spring of the 35kV vacuum circuit breaker, so that the long time consumption of the traditional method can be avoided, the potential safety hazard of mechanical injury to people can be prevented, and the operation risk is reduced;
2. economic benefits
By adopting the portable disassembling tool for the spring of the 35kV vacuum circuit breaker, the overhaul time of the equipment is greatly shortened, the power failure time of the equipment is reduced, the annual utilization rate of the equipment is improved, and for a power grid enterprise, the portable disassembling tool means that the equipment can output as much electric quantity as possible and obtain more economic benefits;
3. improving the reliability of the power grid
To only double-circuit power supply in the transformer substation, the incoming wire of the same way has a power failure and overhauls and can increase the risk of electric wire netting operation, uses the portable instrument of dismantling of 35kV vacuum circuit breaker spring that can be applied to, reduces the activity duration, shortens the power off time of equipment, makes the earlier operation of putting into operation of power off equipment than applying for the power off time, has improved the reliability of electric wire netting operation.
The above description is only for the specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto, and any person skilled in the art can easily think of the changes or substitutions within the technical scope of the present invention, and all should be covered within the protection scope of the present invention, therefore, the protection scope of the present invention should be subject to the protection scope of the claims.
