Description

The reinforced protection device for urban transportation rail current potential

Technical field

The present invention relates to urban transportation rail Potential Technology field, and in particular to one kind is reinforced to be directed to urban transportation rail current potential Protection device.

Background technology

Urban track traffic tractive power supply system is powered using overhead contact line, using rail as current return circuit.To reduce Stray electrical current produces corrosion to civil engineering structure reinforcing bar, rail, equipment metal shell and other underground metal pipelines, and track traffic is built If more perfect fountain measure is taken during.I.e.：DC traction power-supply system is designed as isolated neutral system, Insulating mounting is used to DC suppling equipment, rail is insulated by felt pad and the earth, to reduce the leakage of stray electrical current.Work as confession When electric section has the train for starting or running or system short-circuit fault occurs, because of path and steel of the rail as traction current The presence of transition resistance between rail and ground, it is poor that rail produces certain floating potential over the ground.To prevent that rail potential to ground is too high Personal injury is caused, each station and parking lot need to be provided with Rail potential protection device (HVL).

Thus a kind of Rail potential protection device is just proposed, including programmable controller, contactor, IGCT trigger by force Module, anti-parallel thyristor assembly module and voltage detection module；Wherein, for detecting the electricity of voltage between rail and protecting field Detection module is pressed to be connected with programmable controller communication, contactor and the anti-parallel thyristor component is series at rail and protection Between ground, the contactor is connected with programmable controller communication, and the anti-parallel thyristor component is triggered by force by IGCT The communication of module and programmable controller connects, the strong trigger module of IGCT respectively with two in anti-parallel thyristor component The control terminal connection of IGCT；The magnitude of voltage that the programmable controller returns according to voltage detection module controls the contactor Closure and disconnection with anti-parallel thyristor component.

The programmable controller is the EASY 256275 of model programmable controller.

The method of work of the other Rail potential protection device includes, the voltage detection module detection rail and protection Voltage difference between ground, and voltage difference data is returned into the programmable controller；

When the voltage difference between the rail and protecting field that voltage detection module detects is more than one section of operation voltage value U1, Controlled by Programmable Controller contactor closes a floodgate, and Controlled by Programmable Controller contactor recovers to disconnect after the first setting time value t；

When the voltage difference between the rail and protecting field that voltage detection module detects is more than two sections of operation voltage value U2, Controlled by Programmable Controller contactor forever closes a floodgate, and no longer control contactor recovers to disconnect；

When the voltage difference between the rail and protecting field that voltage detection module detects is more than three sections of operation voltage value U3, The strong trigger module of Controlled by Programmable Controller IGCT makes anti-parallel thyristor component be turned on first in 1ms, makes rail with protecting The connection of shield ground；Then Controlled by Programmable Controller contactor closes a floodgate；After the contactor closes a floodgate, Controlled by Programmable Controller crystalline substance lock Managing strong trigger module makes anti-parallel thyristor component disconnect immediately.

When the voltage difference between the rail and protecting field that voltage detection module detects is more than one section of operation voltage value U1, Controlled by Programmable Controller contactor closes a floodgate, and Controlled by Programmable Controller contactor recovers to disconnect after being set the time；If In two setting time value TT1 after Controlled by Programmable Controller trigger continuous action 3 times, the programmable controller no longer controls Contactor acts, and the trigger remains the state of constant combined floodgate.

The value of one section of operation voltage value U1 meets DC25V ＜ U1 ＜ DC200V.

The value of two sections of operation voltage values U2 meets U2=DC150V.

The value of three sections of operation voltage values U3 meets U3=DC480V or U3=DC600V.

The value of the first setting time value t meets 0.1s ＜ t ＜ 5s.

The value of the second setting time value TT1 meets 30s ＜ TT1 ＜ 120s.

This programme causes the Rail potential protection device with having continuous monitoring station building and operation rail traction The function of ground contact voltage, if occurring big potential difference between rail and protecting field, according to the rank of potential difference to the two The short circuit of different modes is carried out, for producing dangerous electricity between vehicle with preventing station building with operation rail and thereon Pressure, with protection staff and the safety of facility.
