Description
Technical field
The present invention relates to the operating power of power system transformer substation and the control field of communication power supply, is specifically a kind of DC power supply automatic control equipment.
Background technology
Along with the development of intelligent grid, transformer station will progressively realize unattended, and this intelligent requirements for Substation Operating power-supply system and the power supply system for communications is more and more higher.The Substation Operating power-supply system of take is example, in existing transformer station, usually use two to overlap standby each other operating power system, after the incoming call power down of a set of operating power system wherein, during its storage battery power supply, need to its direct current supply bus switching be connected on the direct current supply bus of another set of operating power system by mode manually, the setting of transformer substation communication power-supply system is also like this.Owing to must manually switching, can not automatically switch, hinder the realization of Unattended substation.
Summary of the invention
The purpose of this invention is to provide a kind of DC power supply automatic control equipment, after making transformer station's standby two cover operating power systems arbitrary cover system incoming call power down therein each other, can both automatically switch and be connected to another set of operating power system.This DC power supply automatic control equipment also is applicable to the power supply system for communications of transformer station.
Realize that technical scheme of the present invention is: a kind of DC power supply automatic control equipment comprises that D.C. contactor KM and direct voltage detect controller; The main contacts two ends of often opening of D.C. contactor KM are connected to the first DC power supply bus HM1 and the second DC power supply bus HM2, and the coil of D.C. contactor KM is connected to the control loop that direct voltage detects controller; Direct voltage detects controller and also is provided with for detection of the first voltage detecting end J1 of the voltage of the batteries that is connected to the first DC power supply bus HM1 with for detection of the second voltage test side J2 of the voltage of the batteries that is connected to the second DC power supply bus HM2.
The Substation Operating power-supply system of take is example, principle of the present invention is, by what the DC power supply buses of two cover operating power systems of transformer station were connected respectively to D.C. contactor, often open the main contacts two ends, the control loop of direct voltage detection controller is connected to the coil of D.C. contactor, and the voltage of the batteries that is connected to the DC power supply bus is detected respectively in two test sides.When two cover operating power systems all worked, the D.C. contactor main contacts disconnected, and two cover operating power systems are respectively load supplying separately.After the AC dump of the first operating power system, the first operating power system is namely by batteries power supply, voltage slow decreasing in the batteries discharge process; DC voltage detector detects the voltage drop of batteries of the first operating power when the predefined magnitude of voltage, its control loop makes the conducting of D.C. contactor coil, the conducting thereupon of the main contacts of D.C. contactor, the DC power supply bus of two cover operating powers is communicated with, and the second operating power system is the load supplying of two cover operating powers simultaneously.After the interchange incoming call of the first operating power system, when the voltage that DC voltage detector detects the batteries of the first operating power rises to predefined magnitude of voltage, namely disconnect the D.C. contactor coil, the main contacts of D.C. contactor is disconnected, and two cover operating power systems return to normal operating conditions.After the AC dump of the second operating power system, its operating state and aforementioned process are similar.Like this, by this DC power supply automatic control equipment, make two cover operating power systems realize automatic switchover, each other standby function.
The DC power supply automatic control equipment has solved effectively that the operating power system in current transformer station and power plant and the power supply system for communications exist can only manual switchover realizes two cover operating power systems standby bottleneck each other, simple in structure, reliability is high, is conducive to promote the use of.
