Description
Technical field
The present invention relates to power grid O&M field, PT fuse repairing auxiliary device outside especially a kind of room 35kV.
Background technique
In 35kV substation, outdoor 35kV PT device fuse failure rate is higher, and it is located on insulating support, distance
There is a certain distance on ground, and when maintenance need to carry out high altitude operation.Fuse is located in seal (insurance oversheath), and one end is
Shell (insurance protecting cover) with spring.When being overhauled and being replaced to fuse, need to open the shell with spring, due to
High altitude operation and spring strength is larger, service personnel is inconvenient when installing the shell with spring, more arduously, influences
Operating efficiency and operation safety.
Summary of the invention
It is provided outside a kind of reliable operation and the high-efficient room 35kV it is an object of the invention to solve above-mentioned technical problem
PT fuse repairing auxiliary device.
In order to solve the above-mentioned technical problem, the present invention adopts the following technical scheme:
PT fuse repairing auxiliary device outside a kind of room 35kV, including cross bar, two mobile bars, threaded rod, handle and top
Block, two mobile bar tops can movably be mounted on the two sides of cross bar, and the lower part of two mobile bars to
Inner bending is simultaneously respectively formed with a hook with the flange for hooking insurance oversheath, and the threaded rod runs through threaded connection up and down
In the middle part of cross bar, which is connected with the handle, and lower end is connected with the jacking block, and the jacking block bottom is formed with one
Opening is for accommodating the convex block on insurance protecting cover.
Further, two mobile bar tops are provided with a through-hole, and two mobile bars can be matched by through-hole
Ground is sleeved on cross bar and can move left and right along cross bar, the both ends of cross bar further respectively have a jackscrew to avoid mobile bar from
It skids off and falls off on cross bar.
The beneficial effects of the present invention are:
1. portable, be fixed easily.
2. being convenient for execute-in-place, operating efficiency is promoted, power off time is saved.
3. practical convenient for promoting.
4. ensureing operation safety.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of PT fuse repairing auxiliary device outside the room 35kV of the present invention.
Specific embodiment
The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments:
Referring to Fig. 1, PT fuse repairing auxiliary device includes 1, two mobile bar 2, spiral shell of cross bar outside the room 35kV of the invention
Rasp bar 3, handle 4 and jacking block 5.
Two 2 tops of mobile bar can movably be mounted on the two sides of cross bar 1, and two mobile bars 2
Lower part bends inwards and is respectively formed with a hook with the flange for hooking insurance oversheath 8.
About 3 threaded rod is connected with the handle 4 through 1 middle part of cross bar, 3 upper end of threaded rod is threaded in,
Lower end is connected with the jacking block 5, and the handle 4 is a stock being laterally arranged, 5 bottom of jacking block be formed with an opening with
For accommodating the convex block on insurance protecting cover 7.
Further, two 2 tops of mobile bar are provided with a through-hole, and two mobile bars 2 by through-hole can
It is sleeved on cross bar 1 and can be moved left and right along cross bar 1 with ground, further respectively have a jackscrew 6 at the both ends of cross bar 1 to avoid shifting
Lever 2 is skidded off from cross bar 1 to fall off.
When work, the hook of two mobile bars 2 hooks the flange of insurance oversheath 8, and swing handle 4 passes through 3 band of threaded rod
Dynamic jacking block 5 presses on insurance protecting cover 7, and the convex block insured on protecting cover 7 at this time is contained in just in the opening of 5 bottom of jacking block, and
Convex block will not generate interference to it when jacking block 5 rotates, and press apart from adjusting and using jacking block 5 by rotating handles 4 again later
Tight insurance protecting cover 7 generates biggish power output using lesser strength using theory of mechanics, thus not only fast but also quietly installation insurance
Protecting cover 7.
The device of the invention is replaced manually using mechanical force, which has the characteristics that easy to carry and be fixed easily.With
The device can fix shell using mechanical force when installing shell (the insurance protecting cover) with spring, it is not only pacified fastly but also surely
Dress, to promote operating efficiency and ensure operation safety.
In conclusion the contents of the present invention are not limited in the above embodiments, those skilled in the art can be
It is proposed other embodiments within technological guidance's thought of the invention, but these embodiments be included in the scope of the present invention it
It is interior.
