Specific embodiment
The invention will be further described with reference to the accompanying drawing.
The present invention discloses a kind of power distribution unit of operation type remote-controlled vehicle, specifically operation type remote-controlled vehicle
Power distribution unit receive the power supply that supplies on ship, and power safety is reasonably distributed to each use of whole system
Electric equipment.Its main function includes that the power supply met the requirements is provided to each power unit, the energy of reasonable distribution ship electricity, and high pressure is defeated
Electricity reduces line loss, and the quality and ground fault to power supply line carry out real-time monitoring, to electrical equipment electric current and voltage etc.
Parameter carries out real-time monitoring etc..
Pointer voltmeter is mounted on to the input terminal of power distribution unit, can be measured under conditions of not power supply to the device
Input voltage size, Quality analysis of power instrument can the information such as voltage, electric current, frequency to input power be monitored.Electric current
Tested electric current and information of voltage can be sent to Node Controller by transmitter and voltage transmitter, and insulating monitor is opposite underwater
The circuit of equipment power supply carries out real-time monitoring.
One kind being used for operation type remote-controlled vehicle power distribution unit, including submersible oil sources motor current supply circuit, relaying
Device oil sources motor current supply circuit, submersible underwater electronic equipment current supply circuit etc..The power supply and protection in each circuit have independence
Switch control, and per to power all the way all be by two switch series controls of breaker and A.C. contactor device.
Power distribution cabinet panel can show power status and state of insulation of submersible and repeater etc., and be provided with
Scram button.
Power dispensing cabinet is used based on programmable ethernet node controller as central control unit, it receives and comes from
Power distributes the button of cabinet panel and the signal of cabinet inner sensor.
Pointer voltmeter can measure input voltage size under conditions of not power supply to the device, and Quality analysis of power instrument can
It is monitored with information such as voltage, electric current, frequencies to input power.Current transducer and voltage transmitter can be by tested electricity
Stream and information of voltage send Node Controller, the insulation situation of insulating monitor real-time monitoring route to.
As shown in Figure 1, three-phase 380V ship electricity will be examined before entering power distribution unit master switch Q1 by pointer voltmeter
Voltage value is measured, master switch can be opened when voltage value is in normal range (NR), the device power then powered on to needs avoids
It is damaged caused by equipment since the power supply of ship electricity is abnormal.Several current supply circuits of power distribution unit have independent switch
It is controlled, once certain is abnormal all the way, can individually disconnect the road power supply, not influence the normal use in remaining each circuit.
In addition underwater power circuit, which powers on, needs certain condition, equipment is otherwise easily damaged, so underwater power circuit switching is by breaking
Road device and A.C. contactor are used in series (such as Q2 and KO1), open and two switches is needed to simultaneously close off, and prevent from going out in use process
Equipment damage caused by existing maloperation.Since underwater robot needs to carry out operation in a few km depth of waters, electric energy passes at a distance
It is defeated, so reducing line loss using high-voltage transmission.380V electricity is increased in power distribution unit by step-up transformer
3000V is powered underwater equipment, these routes will bring uncertain disaster in case of insulation fault to system.
So tetra- road transmission line of electricity of Dui Zhe will carry out real-time insulation monitoring.Insulating monitor is connected to ungrounded electric net work (IT) and the earth
Between, the ground fault of exchange IT power grid can be monitored in real time, when insulating resistance value is lower than the lower limit of setting value, insulating monitor
Instruction is issued, makes the breaker actuation in the low-pressure section of this route, thus by the dump on this route.If hair
Existing ground fault, and for the degree center line isolated neutral system of this failure, it not will lead to dangerous generation immediately, then
It can be switched by one " bypass ", select Earth Fault Detection invalid, thus allow to continue to complete reclaimer operation, equipment recycling
After on to deck, then power supply line is checked.The network voltage that general monitor can be directly monitored by is no more than 660V, but
It separately plus after coupler can extend to 3000V or more.Such as the insulation monitoring that Fig. 2 a, Fig. 2 b are submersible and repeater motor
Figure.Winding to the transformer coil that two motors are powered is " triangle/star " type connection, and transformer time pole winding is connect using star-like
Method extracts the neutral conductor, this root neutral conductor is not intended for submersible machine, and is served only for insulating monitoring, the advantage of doing so is that
The measurement voltage for reducing insulating monitor, can choose a little bit smaller high-voltage adapter.Voltage transmitter and current transducer
The voltage and current information of real-time monitoring power supply circuit, and this information is transmitted in control system by Node Controller.
Since the power of carrier motor is bigger, every phase is powered for it using 2 conductor in parallel in cable, 3 Xiang Gongxu
Want 6 conducting wires.These arrangement of conductors will bear the deformation such as flexion torsion, so inevitably breaking in armour cable, deck cable and heaving pile
Situations such as line and quality are deteriorated.How such case is detected, it is most important for normal power supply to ensureing.
Here prepare to be measured in real time cable quality using method as shown in Figure 3.6 conducting wires are divided into 2 groups, every group
The inside respectively includes U, V, W three-phase.Add zero sequence current mutual inductor wherein one group of outside, the electric current of mutual inductor output should be
The vector sum of three-phase current, when line quality is intact, the output of mutual inductor is zero, when any one appearance event in 6 lines
After barrier, by the current imbalance of mutual inductor, there is constant current output.Earth-fault relay is given in the output of mutual inductor,
After electric current is more than a certain setting value, the actuating of relay or is sounded an alarm cut-off loop.
The operation principle of the present invention is that:
The power distribution unit of operation type remote-controlled vehicle receives the power supply supplied on ship, according to the use of electrical equipment
The power safety met the requirements is reasonably distributed to each electrical equipment by electricity demanding.During electric energy distribution, to each
The power quality of electrical equipment is detected, and is protected to electrical equipment, prevents electrical equipment from damaging.
In conclusion it has knot The present invention gives a kind of power distribution unit for operation type remote-controlled vehicle
Many advantages, such as structure is simple, easy to operate, and high reliablity is at low cost, and defencive function perfects, provides for operation type remote-controlled vehicle
Reliable and stable power supply.
