Description
Technical field
The present invention relates to urban transportation rail Potential Technology field, and in particular to a kind of multi-functional needle is 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 during take more perfect fountain measure.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 with the earth, to reduce the leakage of stray electrical current.Work as confession
When electric section has the train for starting or running or occurs system short-circuit fault, 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 rail potential to ground 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 are triggered by force
Module, anti-parallel thyristor assembly module and voltage detection module;Wherein, for detecting the electricity of voltage between rail and protecting field
Pressure detection module is connected with programmable controller communication, and 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 is connected, the strong trigger module of IGCT respectively with two in anti-parallel thyristor component
The control end connection of IGCT;The magnitude of voltage that the programmable controller is returned 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 is detected 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 is detected 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 is detected 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 and guarantor
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 is detected is more than one section of operation voltage value U1,
Controlled by Programmable Controller contactor closes a floodgate, and is set Controlled by Programmable Controller contactor after the time and recovers to disconnect;If
In two setting time value TT1 after Controlled by Programmable Controller trigger continuous action 3 times, the programmable controller is no longer controlled
Contactor is acted, 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, to protect the safety of personnel and facility.
But in further applying, there are the following problems for the system:
The programmable controller is arranged in the hollow cabinet of rectangular-shape, because during programmable controller work usually
There is the elevated situation of temperature, so need to perform programmable controller cooling, but current cooling system is typically only
In setting an air exhauster in a side wall of the shell of the programmable controller, exhaust is performed to the programmable controller,
, only can be to described during exhaust because air exhauster is only configured in a side wall of the shell of the programmable controller
One side wall of programmable controller realizes cooling, and temperature reduction performance is poor, and exhaust cooling can not be more preferably to described by gas in addition
Programmable controller realizes and conformed to that temperature reduction performance is poor, and the gas that it is discharged relies on certain stroke to perform, it is impossible to constitute disorderly
Stream so that suffered with the programmable controller and connect imperfect, temperature reduction performance is poor, so performs cooldown period inside the cabinet
Between, because often also there is the temperature inside the air exhauster for other electronic unit, cabinet not low inside cabinet, with reference to
The not low gas of cabinet temperature inside performs cooling to the programmable controller, it is impossible to realize more preferable temperature reduction performance, described
The causing in exhaust process of air exhauster and the air exhauster for the programmable controller for other electronic unit
The air-flow of motion is interfered with each other, and the particulate contaminant inside the cabinet is kicked up and sticks at the programmable controller wall and also allows
Temperature reduction performance is worse, and simply gas cools in addition, and temperature reduction performance is also poor.
