Abstract
Scalable cable protecting tube, relates to cable protecting tube, and in order to solve, equipment in winter is asynchronous with the change in location of mechanism case affects the problem that equipment is properly functioning.Lower tube section closely surrounds the bottom of pipeline section, and one end of N wires is all detachably connected to the outside of pipeline section, and the other end of N wires is all detachably connected to the outside of lower tube section, N >=1.This utility model ensure that the properly functioning of equipment and mechanism case.This utility model is applicable to northern area protection cable.
Description
Technical field
This utility model relates to cable protecting tube, is specifically related to telescopic cable protecting tube.
Background technology
The Northeast of China, winter temperature is too low, throughout the year since freeze injury on the impact of the Northeast's power equipment more
Seriously, the harm to equipment especially operating mechanism case is more obvious, soil freeze injury in winter, due to equipment Foundations and backfill soil
Frozen-heave coefficient is different, and equipment will not occur Tong Bu change with mechanism case position, causes mechanism case position that bigger change, harm occur
Equipment is properly functioning, in some instances it may even be possible to cause chain accident.
Utility model content
The purpose of this utility model is that equipment in winter is asynchronous with the change in location of mechanism case is just affecting equipment in order to solve
The problem often run, thus scalable cable protecting tube is provided.
Scalable cable protecting tube described in the utility model, including upper pipeline section, lower tube section and N wires, N >=1；
Lower tube section closely surrounds the bottom of pipeline section, and one end of N wires is all detachably connected to outside pipeline section
Side, the other end of N wires is all detachably connected to the outside of lower tube section.
Scalable cable protecting tube described in the utility model solves conventional single hose cable protecting tube owing to freeze injury is to setting
The standby infringement with mechanism case, the top of upper pipeline section is fixed bindiny mechanism's case, the bottom of upper pipeline section and the bottom of lower tube section and is all embedded in
Underground, when backfill soil occurs freeze injury, scalable cable protecting tube has enough distance of stretch out and draw backs, enough makes mechanism case and and mechanism case
The position of the equipment connected occurs to synchronize change, will not impact mechanism case, when upper pipeline section and lower tube section stretch, if
The too small possible generation eddy current of contact area between two pipes, connects upper pipeline section and lower tube section by metal wire, is not affecting pipe
Section and lower tube section stretch on the premise of ability, and the generation that not only avoid eddy current also assures that the reliability of ground connection, to mechanism case
Each side play one equilibrium protection, ensured the safe operation of transformer station.
Simple in construction of the present utility model, it is adaptable to northern area protection cable.
Accompanying drawing explanation
Fig. 1 is the structural representation of the scalable cable protecting tube described in detailed description of the invention one；4 is mechanism case.
Detailed description of the invention
Detailed description of the invention one: illustrate present embodiment with reference to Fig. 1, the scalable cable protection described in present embodiment
Pipe, including upper pipeline section 1, lower tube section 2 and N wires 3, N >=1；
Lower tube section 2 closely surrounds the bottom of pipeline section 1, and one end of N wires 3 is all detachably connected to pipeline section 1
Outside, the other end of N wires 3 is all detachably connected to the outside of lower tube section 2.
Detailed description of the invention two: present embodiment is to make the scalable cable protecting tube described in detailed description of the invention one into one
Step explanation, in present embodiment, N=1.
Use a wires 3 both to save resource, the generation of eddy current can be avoided again to can also ensure that the reliability of ground connection.
Detailed description of the invention three: present embodiment is to make the scalable cable protecting tube described in detailed description of the invention two into one
Step explanation is described further, and in present embodiment, the bottom of upper pipeline section 1 and the bottom of lower tube section 2 are all embedded in underground, upper pipeline section
1 length being embedded in underground is 20cm, and it is 30cm that lower tube section 2 is embedded in the length of underground.
Upper pipeline section 1 described in present embodiment and lower tube section 2 are embedded in the length of underground can make cable protecting tube firmly solid
Determine on the ground.
Detailed description of the invention four: present embodiment is to make the scalable cable protecting tube described in detailed description of the invention three into one
Step explanation is described further, in present embodiment, metal wire 3 all by screw and nut be connected to the outside of upper pipeline section 1 with
The outside of lower tube section 2.
It is attached by screw and nut, simple to operate, low cost, it is simple to commonly used.
Detailed description of the invention five: present embodiment is to make the scalable cable protecting tube described in detailed description of the invention four into one
Step explanation is described further, and in present embodiment, the space between upper pipeline section 1 and lower tube section 2 is full of conducting resinl.
Lower tube section 2 closely surrounds on pipeline section 1, and the space between upper pipeline section 1 and lower tube section 2 is full of conducting resinl, increases
Upper pipeline section 1 and lower tube section 2 Earthing Reliability.
