Core link of the transformer station as power system, it is used to collect power supply, buck/boost and distribution electric energy, is responsible for region
High-low pressure conversion and power supply task, therefore, the safe operation of transformer station is most important to power system.In order to ensure transformer station
Reliable and stable operation, existing transformer station is generally equipped with flood monitoring system and supply and drain water system.Wherein, transformer station's flood monitoring
System generally receives the control signal that sends of controller to carry out water level monitoring using ultrasonic sensor.
In order to monitoring substation flood monitoring system whether normal work, people's usually from transformer station's flood monitoring system matches somebody with somebody
Have indicator lamp.Because LED lamp bead has small volume, low cost and other advantages, therefore people are usually using LED lamp bead as transformer station's water
Soak the indicator lamp of monitoring system.LED lamp bead needs more lamp beads to be together in series or parallel and could work when in use, using parallel connection
Mode drives the voltage needed for multiple LED lamp beads relatively low, but because the forward voltage drop of each LED lamp bead is different, therefore each LED
The brightness of pearl is different.When using tandem type type of drive when, the brightness of each LED lamp bead is identical, but one of them or it is several
LED lamp bead break down and it is breaking when, can make circuit occur open circuit and cisco unity malfunction.
The content of the invention
It is an object of the invention to overcome the deficiencies of the prior art and provide a kind of LED is driven by the way of series connection
Pearl, and it is avoided that circuit occurs to refer in transformer station's flood monitoring system of open circuit when one or several LED lamp beads break down
Show the driver of lamp.
The purpose of the present invention is achieved through the following technical solutions：The driving of indicator lamp in transformer station's flood monitoring system
Device, including rectification module and the LED lamp bead group that is connected with rectification module, the rectification module include bridge rectifier, first
Electric capacity and the first diode, the bridge rectifier are provided with two inputs and two output ends, and the one of bridge rectifier
Be connected with thermistor on individual input, an output end of bridge rectifier connect after the first diode with LED lamp bead group
Connect, be connected with ground wire in another output end of bridge rectifier, the both ends of first electric capacity are connected to bridge
In two output ends of formula rectification circuit；The LED lamp bead group includes the LED lamp bead of multiple series connection, each in LED lamp bead group
The voltage-stabiliser tube of a reversal connection, the output head grounding of the LED lamp bead group are parallel with LED lamp bead.The present invention is in use, bridge
Two inputs of formula rectification circuit receive the input of supply voltage.The conducting voltage of each LED lamp bead should be than it in the present invention
The voltage stabilizing value of upper voltage-stabiliser tube in parallel is low, and otherwise voltage-stabiliser tube in parallel can shunt one part of current and make LED lamp bead dimmed very
To not working.
The LED lamp bead group includes three LED lamp beads.
Compared with prior art, the invention has the advantages that：Overall structure of the present invention is simple, is easy to implement, this
During invention application, the branch road that voltage-stabiliser tube in parallel is formed in each LED lamp bead forms the protection circuit of the present invention, as some LED
When the lamp bead of lamp bead occurs breaking, voltage-stabiliser tube connected in parallel is devoted oneself to work, so as to be avoided that open circuit occurs for circuit；The present invention adopts
LED lamp bead is driven with the mode of series connection, and the brightness in each LED lamp bead is consistent, is easy to the popularization and application of the present invention.
