Every be provided with line joint layer 2.Temperature sensing optical cable 8 is laid with every high-tension line 1.High-tension line described in the utility model
1 is 110kV and above high-tension line.When piping lane interior environment temperature changes or short trouble occurs for circuit, it will cause
The temperature of circuit changes, and this will produce a lateral pull in line-internal.When line linear lays pulling force within 6kN
When, straight-run can be used；When line linear laying pulling force is more than 6kN, circuit in pipe gallery electric power storehouse can be with
Laid using vertical sinusoidal, and then reduce circuit pulling force.The utility model is so that sinusoidal is laid as an example, as shown in figure 3, head and the tail
Insulating joint 9 and grounding resistance 10 are respectively provided with, as shown in Fig. 2 after heating, high-tension line 1 has a lateral displacement n, becomes
Circuit 1 ' after heating.If straight-run, a lateral displacement n is also had, so as to turn into sinusoidal.
Any point non_direct ground on the metal level that single circuit one returns in AC system during line conductor normal work
The normal induction voltage at place, typically cannot be greater than 50V.Because of 110kV three phase supplies loop, except being laid in lake, the inferior place of seawater
And circuit section it is little when can be selected three-hole outside, every time can be selected 3 single circuits.More than 110kV three phase supplies loop, often
3 single-core cables are selected in response.
Pipe gallery electric power cabin route laying mode determines principle：1. when line linear is laid and its circuit pulling force is expired
Foot requires (it is generally acknowledged that circuit pulling force should be limited in below 6kN), and because of straight-run investment reduction cost and constructs more square
Just, then straight-run preferentially is used, and determines the lateral displacement n of circuit and the half L of circuit sinusoidal wavelength；2. work as circuit
When straight-run circuit pulling force is unsatisfactory for requiring, then sinusoidal laying is considered as, makes its circuit pulling force and line influence voltage
It is satisfied by requiring, and determines the lateral displacement n of circuit and the half L of circuit sinusoidal wavelength.
