Abstract
The invention discloses an anti-freezing device for a power transmission line. The anti-freezing device comprises a griper which grips on the power transmission line, the gripper is composed of two parallel electric conduction clips, an electric heating component and a temperature contact switch are in series connection with the two electric conduction clips, the portion gripped by the gripper on the power transmission line, the electric heating component, and the temperature contact switch form an electric heating loop. Compared with the prior art, the anti-freezing device for the power transmission line has the advantages of simple structure, reasonable design, wide application range, and capability of effectively solving the technical problem of power grid accidents due to abruption of power transmission lines caused by freezing.
Description
Technical field
The present invention relates to the protector of transmission line, especially a kind of transmission line is prevented freezing device.
Background technology
Transmission line can make the transmission line fracture when freezing in freezing day and power grid accident takes place.Preventing the method that transmission line froze in freezing day at present, mainly is that manual work is rooted out, and efficient is low, and labour intensity is big, and danger is very big.
Summary of the invention
The objective of the invention is to: provide a kind of transmission line simple in structure, reasonable in design, applied widely to prevent freezing device.
For realizing above-mentioned purpose, the present invention can take following technical proposals:
A kind of transmission line of the present invention is prevented freezing device; Comprise the clamper that is held on the transmission line; Said clamper is made up of two parallel conductive clips; Be connected in series with electrothermal device and temperature contact switch between said two conductive clips, transmission line constituted the electric heating loop by the part of said clamper clamping and conductive clip, electrothermal device and temperature contact switch.
Said temperature contact switch is closed when temperature is lower than zero degree, when temperature is higher than zero degree, breaks off.
Compared with prior art the invention has the beneficial effects as follows: owing to adopt technique scheme, transmission line constituted the electric heating loop by the part of said clamper clamping and conductive clip, electrothermal device and temperature contact switch, when winter temperature on the transmission line is lower than zero degree and freezes; The temperature contact switch is closed; Little current on the transmission line flows through electrothermal device, and electrothermal device makes the transmission line heating, and temperature rises; Melt the ice and snow on the transmission line, thereby reach anti-freeze effect; When temperature was higher than freezing temperature, the temperature contact switch broke off, and electrothermal device is inoperative.This transmission line simple in structure, reasonable in design, applied widely is prevented freezing device, can effectively solve the technical problem that power grid accident takes place because of the freezing transmission line fracture that causes.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Embodiment
As shown in Figure 1; A kind of transmission line of the present invention is prevented freezing device; Comprise the clamper 2 that is held on the transmission line 1; Said clamper 2 is made up of two parallel conductive clips, is connected in series with electrothermal device 3 and temperature contact switch 4 between said two conductive clips, transmission line 1 constituted the electric heating loops by the part of said clamper 2 clampings and conductive clip, electrothermal device 3 and temperature contact switch 4.Said temperature contact switch 4 is closed when temperature is lower than zero degree, when temperature is higher than zero degree, breaks off.On the transmission line 1 of needs protection, the anti-freezing device of a plurality of described transmission lines is set at interval, can effectively imitate the technical barrier that power grid accident takes place because of the freezing transmission line fracture that causes in solution.
Claims (2)
