Description
Technical field
The present invention relates to the contact net voltage type detection technique field of electric locomotive, and in particular to a kind of electric locomotive
Contact net voltage type detecting system and detection method.
Background technology
In recent years, the technical merit of domestic electrical locomotive manufacturing enterprises achieves rapid progress, with national going global
Implementation, domestic relevant enterprise more and more participate in International Power locomotive market.
At present, the electric railway of various countries' main line simultaneously and exist it is a variety of power supply system.According to statistics, whole world supply voltage rail
Standard is up to as many as 28 kinds, but the most frequently used power supply system only has 1.5kV direct currents, 3kV direct currents, 25kV 50Hz etc. several.Due to each
It is national different with the historical tradition of each railway, it is determined that railway equipment standardization direction it is different.Therefore some is only with one kind
Power supply system, the even a variety of power supply systems of some two kinds of uses.Simultaneously using direct current and exchange two kinds power supply make countries have 43 it
More, these countries purchase to reduce locomotive, maintenance cost more options are simultaneously suitable for the electric power machine of AC and DC power supply mode
Car.
Main circuit of electric locomotive switch will use different types of device under different power supply systems, under Alternating Current Power Supply standard
Using line vacuum circuit breaker；High-speed circuit breaker is used under direct current supply standard.The operation principle of two kinds of breakers is different, is applicable
Power supply standard is different, if two kinds of breakers are closed at or high-speed circuit breaker are closed under Alternating Current Power Supply standard, in direct current
Line vacuum circuit breaker is closed under power supply system will produce catastrophe failure, cause the damage of locomotive component.Due to domestic electrified iron
Road is only with a kind of power supply systems of 25kV50Hz, it is not necessary to while suitable for the electric locomotive of AC and DC power supply mode, therefore
There is no corresponding contact net voltage type detecting system.
The content of the invention
The present invention provides a kind of the contact net voltage type detecting system and detection method of electric locomotive, for electric locomotive
Simultaneously be applied to AC and DC power supply mode, propose a kind of contact net voltage type detecting system, it is ensured that electric locomotive according to
Different power supply systems closes corresponding main circuit breaker, avoids the generation of locomotive failure, improves locomotive operation security.
The technical solution adopted in the present invention is the contact net voltage type detecting system of electric locomotive, and electric locomotive is by electricity
Bend PG and obtain electric energy from contact net, voltage detection module TV1 is used for the net pressure signal V for detecting pantograph output, current detecting mould
Block CV1 is used for the current signal I for detecting pantograph output, and the signal of detection is inputed into control unit CVCE, control unit
CVCE is used for output control signal to vacuum circuit breaker HVCB and high-speed circuit breaker HSCB, and vacuum circuit breaker HVCB, which is used to exchange, to be supplied
Main circuit of electric locomotive switchs under electric standard, and high-speed circuit breaker HSCB is used for locomotive main disconnect switch under direct current supply standard.
The contact net voltage type detection method of electric locomotive, under Alternating Current Power Supply standard, voltage detection module TV1 outputs
Net pressure signal V is more than zero, while the current signal I of current detection module CV1 outputs is zero, and control unit CVCE outputs vacuum is broken
Road device HVCB closure signals, control HVCB closures；
Under direct current supply standard, voltage detecting TV1 output net pressures signal V is zero, the electricity of current detection module CV1 outputs
Flow signal I and be more than zero, control unit CVCE output high-speed circuit breaker HSCB closure signals, control HSCB is closed.
The beneficial effects of the invention are as follows：The contact net voltage type detecting system of the electric locomotive of the present invention is not only suitable for handing over
The powered types detection being also applied under stream standard under direct current standard, it is ensured that electric locomotive closes under different power supply systems
Corresponding main circuit of electric locomotive switch, avoids the generation of locomotive failure, improves locomotive operation security.
