Specific embodiment
To make structure of the present utility model and advantage clearer, structure of the present utility model is made below in conjunction with accompanying drawing
It is further described through.
Embodiment one
The utility model provides the modified 10kV American Unit Substations with eyes through hole and protective cover, the American Unit Substation
Main body is metal shell, and high-pressure area and area of low pressure are provided with the inwall of metal shell, is provided with high-pressure area and height
The bushing of voltage cable binding post connection, is provided with the low pressure set being connected with low-voltage cable binding post in area of low pressure
Pipe, also the L-type screw rod 1 including being connected with bushing；
Wherein, the screw thread 2 being connected with bushing is provided with one end of L-type screw rod 1, is provided with the other end of L-type screw rod
The eyes through hole for being fixed high-tension cable binding post 4 by bolt 3, is provided with for accommodating on the outside of the bushing
The protective cover 5 of L-type screw rod 1 and high-tension cable binding post 4.
In force, in the prior art, the screw rod in the elbow-type being connected with bushing or T-shaped cable accessory is cylinder
Body, screw thread is equipped with the two ends of cylinder, and the screw thread of one end is used to screw in bushing, realizes the company relative to bushing
Connect, the screw thread of the other end is used to install nut so that the high-tension cable binding post between two sections of screw threads is fixed on spiral shell
On bar, so as to realize the connection relative to bushing.
In order to shorten the installation difficulty of elbow-type in the prior art or T-shaped cable accessory, as shown in figure 1, in the utility model
The screw rod of cylindrical shape is replaced with into L-type screw rod 1, one end of L-type screw rod 1 is provided with the screw thread 2 being connected with bushing, L-type spiral shell
The other end of bar 1 is provided with eyes through hole, and through hole is again provided with high-tension cable binding post 4, makes bolt 3 sequentially pass through two
Through hole, most high-tension cable binding post 4 is fixed with L-type screw rod 1 at last.
As shown in Fig. 2 be additionally provided with protective cover 5 on the outside of bushing, the protective cover 5 is used for by high-tension cable terminals
After son 4 is fixed on L-type screw rod 1, the entirety that the two is constituted is protected, on the one hand prevent maintenance personal favorite in maintenance process
Outer touching causes to get an electric shock, and on the other hand can also prevent conductor from touching during American Unit Substation normally runs, and causes short circuit
Generation.After protective cover 5 is set up, can cause intuitively observe the inner high voltage cable connecting terminal of protective cover 5 and L-type screw rod
1 connection, therefore window can also be provided with protective cover 5.
Relative to the screw rod of cylindrical shape of the prior art, the utility model proposes L-type screw rod 1 can keep beautiful
On the premise of formula case becomes compact effect, by the shape for converting screw rod so that operating personnel are connect using instrument to high-tension cable
When line terminals 4 are dismounted, it is obtained in that as operating personnel provide bigger operating space, so as to improve high-tension cable binding post tear open
The convenience of dress, while making a mess of the probability of the bushing in case change when reducing dismounting, prevents the phenomenon of oil leak.It is double in addition
Eye through hole more can effectively prevent from being relatively rotated between L-type screw rod 1 and high-tension cable binding post 4, improve connection
Stability.
Optionally, the cross section of the L-type screw rod 1 is rectangle.
In force, because end of the high-tension cable binding post 4 with through hole is laminated structure, therefore by L-type screw rod 1
Cross section be set to rectangle, so when high-tension cable binding post 4 is connected with L-type screw rod 1, the two be based on plane connection
, therefore, it is possible to obtain more stable effect, and high-tension cable binding post 4 can also be prevented with L-type screw rod 1 due to occurring
Point-like contacts cause the generation of electrion, improve security.
Optionally, the diameter of the eyes through hole is identical with the diameter of high-tension cable binding post end vias.
In force, the diameter of two through holes is identical, so using the bolt that matches with two through-hole diameters by height
When voltage cable binding post 4 is fixed with L-type screw rod 1, more stable effect can be obtained, and high-tension electricity can also be prevented
Cable binding post 4 causes the generation of electrion with L-type screw rod 1 due to there are point-like contacts, improves security.
Optionally, the bushing is horizontally disposed in metal shell inwall.
In force, in existing American Unit Substation mesohigh sleeve in isosceles triangle or arranged askew, in order to coordinate this
, can also be revised as the position of multiple high pressure sleeves horizontally arranged by the L-type screw rod that utility model is proposed, can so increase
Operating space in unloading process.
For the utility model proposes the modified 10kV American Unit Substations with eyes through hole and protective cover, such as Fig. 3 institutes
Show, be using step specifically：
Step one, by L-type screw rod screw-in bushing；
Step 2, the screw rod in bolt is sequentially passed through the eyes through hole and high-tension cable binding post on L-type screw rod
On through hole；
Step 3, the nut in bolt is screwed on screw rod, completes high-tension cable binding post relative to L-type screw rod
It is fixed.
The utility model proposes the modified 10kV American Unit Substations with eyes through hole and protective cover, in metal shell
Inwall is provided with high-pressure area and area of low pressure, and the gland high being connected with high-tension cable binding post is provided with high-pressure area
Pipe, is provided with the L-type screw rod being connected with bushing on high voltage bushings.Original cylindric spiral shell is replaced by using L-type screw rod
Bar, can be on the premise of the compact effect of American Unit Substation be kept, by the shape for converting screw rod so that operating personnel are using work
When tool is dismounted to high-tension cable binding post, it is obtained in that for operating personnel provide bigger operating space, so as to improve high pressure
The convenience of cable connecting terminal dismounting, while making a mess of the probability of the bushing in case change when reducing dismounting, prevents Lou
The phenomenon of oil.
Each sequence number in above-described embodiment is for illustration only, and the elder generation during the assembling or use of each part is not represented
Afterwards sequentially.
Embodiment of the present utility model is the foregoing is only, is not used to limit the utility model, it is all in the utility model
