Specific implementation mode
The utility model is described in further detail below in conjunction with the accompanying drawings.
The utility model discloses a kind of power distribution unit of operation type remote-controlled vehicle, and specifically operation type remote control is latent
The power distribution unit of hydrophone receives the power supply supplied on ship, and power safety is reasonably distributed to each of whole system
A electrical equipment.Its main function includes providing the power supply met the requirements to each power unit, and the energy of reasonable distribution ship electricity is high
Pressure transmission of electricity, reduces line loss, quality and earth fault to supply line are monitored in real time, to electrical equipment electric current and electricity
The parameters such as pressure carry out monitoring etc. in real time.
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 be monitored the information such as the voltage, electric current, frequency of input power.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 is monitored in real time.
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 be by breaker and the switch series controls of A.C. contactor device two per powering all the way all.
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 voltages, electric current, frequency to input power.Current transducer and voltage transmitter can be by tested electricity
Stream and information of voltage send Node Controller to, and insulating monitor monitors the insulation situation of circuit in real time.
As shown in Figure 1, three-phase 380V ships 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
Due to the abnormal damage caused by equipment of ship electricity power supply.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 during use
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 circuits will bring uncertain disaster in case of insulation fault to system.
So tetra- road transmission lines 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 earth fault of exchange IT power grids can be monitored in real time, when insulating resistance value is less than the lower limit of setting value, insulating monitor
Instruction is sent out, the breaker actuation in the low-pressure section of this circuit is made, thus by the dump on this circuit.If hair
Existing earth fault, and for the degree center line isolated neutral system of this failure, dangerous generation immediately can't be caused, then
It can be switched by one " bypass ", select Earth Fault Detection invalid, to allow to continue to complete reclaimer operation, equipment recycling
After on to deck, then supply line is checked.The network voltage that general monitor can be directly monitored by is no more than 660V, but
Separately plus after coupler it can expand 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 of two motors power supply 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 select a little bit smaller high-voltage adapter.Voltage transmitter and current transducer
The voltage and current information of monitoring power supply circuit in real time, and this information is transmitted to by Node Controller in control system.
Since the power of carrier motor is bigger, per mutually being powered for it using 2 conductor in parallel in cable, 3 phases need altogether
Want 6 conducting wires.These arrangement of conductors will bear the deformations such as flexion torsion in armour cable, deck cable and heaving pile, so inevitably breaking
Situations such as line and degradation.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.One group of outside adds zero sequence current mutual inductor, the electric current of mutual inductor output that should be wherein
The vector sum of three-phase current, when line quality is intact, the output of mutual inductor is zero, when event occurs in any one 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 sends out alarm at cut-off loop.
The operation principle of the utility model is：
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 distributes, to each
The power quality of electrical equipment is detected, and is protected to electrical equipment, prevents electrical equipment from damaging.
In conclusion the utility model gives a kind of power distribution unit for operation type remote-controlled vehicle, it has
Have simple in structure, easy to operate, many advantages, such as reliability is high, at low cost, and defencive function perfects, is operation type remote-controlled vehicle
Provide reliable and stable power supply.
