The explanation of following embodiment be with reference to attached drawing, can be to the specific embodiment implemented to the example present invention.
Fig. 1 is please referred to, the anti-overpressure means of the substation are applied to substation 100, the anti-overpressure means packet of the substation
Include conductive lead wire 10, current sensor 20, diversion pipe 30, container 40, control valve 50 and controller；The one of the conductive lead wire 10
End is electrically connected with the transformer equipment 60 of substation 100, the other end of the conductive lead wire 10 be electrically connected；The current sensor
20 are electrically connected with conductive lead wire 10, to detect the size of the electric current by the conductive lead wire 10；The diversion pipe 30 uses conduction material
Material is made, and one end is electrically connected with the transformer equipment 60 of substation 100, and the other end and ground interval are arranged；The container 40 installation
In above the ground, can be supported by bracket, erecting bed and other load-bearing parts, which is used to store conduction liquid,
The container 40 is connected to setting with diversion pipe 30 by connecting tube 70；The control valve 50 is installed in connecting tube 70, is used to control
The on-off for the connecting tube 70 that diversion pipe 30 is connected to container 40；The controller and current sensor 20 and control valve 50 are electrically
Connection, the controller control turning on or off for the control valve 50 according to the testing result of current sensor 20.
It is worth noting that, it is according to pre-set current value and electricity that when the controller, which controls control valve 50, which turns on or off,
The size relation of the detected electric current by conductive lead wire 10 of flow sensor 20 is closely related, specifically, in current sense
When device 20 detects the real-time current value by conductive lead wire 10 and real-time current value is sent to controller, controller can be by reality
When current value be compared with pre-set current value, if real-time current value be less than pre-set current value, controller control control valve 50
It remains off；If real-time current value is more than or equal to pre-set current value, controller controls control valve 50 and opens, so that
The conduction liquid obtained in container 40 is entered in diversion pipe 30 by connecting tube 70, and continual conduction liquid is downward by diversion pipe 30
Be capable of forming when flowing with the water column that contacts, allow in this way diversion pipe 30 be electrically connected so that substation 100

The impaired problem of conductive lead wire 10, while also improving the safety of the transformer equipment 60 of the substation 100.
It should say, the transformer equipment 60 of the substation 100 is variation by the size of current of conductive lead wire 10, if
When the real-time traffic of the conduction liquid is to maintain constant and too small by the electric current of conductive lead wire 10, then it will lead to conduction liquid and cause
Waste.And the calculation formula of resistance is R=ρ L/S, and wherein ρ is the resistance value of resistance material, and L is the length of resistance material, and S is
Every numerical value of the cross-sectional area of resistance material, the diversion pipe 30 is fixed, therefore can only be formed by changing conduction liquid
The cross-sectional area of water column change the velocity of discharge of the water column of conduction liquid formation, in consideration of it, in one embodiment of this invention,
The adjustable setting of the aperture of the control valve 50；The controller controls control valve 50 according to the testing result of the current sensor 20
Aperture.
Specifically, the control valve 50 is provided with one grade, two grades, N grades of third gear ..., which is provided with continuous electric current
The corresponding one grade of setting in section, i.e. the first electric current section, the corresponding two grades of settings in the second electric current section, third electric current section corresponds to third gear
N electric current section corresponds to N grades of settings, which receives the real-time current value that current sensor 20 detects for setting ...
Afterwards, which electric current section judgement falls in by the real-time current value of conductive lead wire 10, then controls the aperture of control valve 50 again,
The use of conduction liquid can thus be saved.
It should be noted that the diversion pipe 30 is generally made of the preferable material of electric conductivity, such as metallic copper, metal
Aluminium etc., preferably, the contact tube is made of metallic copper, the resistivity ratio of metallic copper is lower, and this makes it possible to reduce this to lead
The resistance of flow tube 30, and then improve the electric conductivity of the diversion pipe 30.

The electric conductivity of the water column of formation is better than conductive lead wire 10, can be fast after allowing for the controller control opening of control valve 50 in this way
The velocity of discharge of the anti-overpressure means of the raising of the speed substation, to be conducive on the transformer equipment 60 by substation 100
Electric current leads to ground, and then is conducive to improve the performance of the anti-overpressure means of the substation.
If conduction liquid contacts with diversion pipe 30 will lead for a long time if should be noted that the conduction liquid has corrosivity
Diversion pipe 30 is caused to be corroded, in consideration of it, the conduction liquid is formed for solution non-corrosive, that conductivity is big, such as sodium chloride or chlorine
Change aluminium, so set, on the one hand ensuring that the diversion pipe 30 will not be corroded, on the other hand ensure that the conduction liquid drains into ground
Soil will not be destroyed.
It is also to be noted that when conduction liquid drains into the external world by diversion pipe 30, if there is the case where strong wind in external environment,
The conduction liquid of one end discharge of transformer equipment 60 from diversion pipe 30 far from substation 100 is easy to appear by big wind action not to be connected
The problem of continuing, being interrupted, in consideration of it, in one embodiment of this invention, which is arranged in a tubular form, i.e. the conductive lead wire
10 can be copper pipe, aluminum pipe etc., which inserts adjacent to one end of the transformer equipment 60 of substation 100
Enter in conductive lead wire 10, which is fixedly connected with the transformer equipment 60 of substation 100.Due to this
Conductive lead wire 10 is directly to be electrically connected with ground, that is to say, that the conductive lead wire 10 is directly to extend on the ground, is ensured that in this way
The water column that conduction liquid is formed not will receive the interference of extraneous factor, and then ensure that the performance of the anti-overpressure means of the substation.
In view of the diversion pipe 30 is spaced with ground, if the transformer equipment of the diversion pipe 30 far from substation 100
Be spaced between 60 one end and ground it is excessive, then can make conduction liquid by the diversion pipe 30 flow downward when, which forms
