Abstract
The invention discloses a kind of underwater electromechanical equipment inverters.Including inverter ontology, install inverter ontology mounting rack, encapsulate inverter ontology the hollow cylindrical pressure-resistant seal container with end cap, it is characterised in that be filled in hollow cylindrical pressure-resistant seal container submergence IGBT module insulating properties heat-conducting liquid medium.The heat that these insulating properties heat-conducting liquids generate when IGBT inverter module works is conducted to the barrel of pressure vessel, it is distributed again by the barrel of pressure vessel into external water, to guarantee that IGBT inverter module is worked normally without overheating, inverter is enable to work long hours at deep-sea.
Description
Technical field
The present invention relates to one kind can be used for various underwater robots, undersea detection towed body equipment, submarine, underwater sampling
Direct current is converted to the underwater electromechanical equipment of three-phase alternating current used in Underwater Engineering equipment with inverse by device, underwater operation station
Become device.
Background technique
Current various deep-sea electromechanical equipment inverters, inverter ontology generally include IGBT inverter module, power panel,
Control circuit board, drive circuit board, small capacitances, big filter capacitor and its charging resistor and short-circuiting contactor, Hall flow element
Deng, due to having to that these elements are isolated with external high pressure seawater when deep ocean work, therefore at present all is with hollow cylindrical it is resistance to
Pressure vessel encapsulates inverter ontology, but IGBT inverter module calorific value therein is larger, cannot radiate well after encapsulation, makes inverse
Becoming device cannot work long hours；And Chang Fashengyin inverter module overheats and generates failure, can not work normally inverter.
Summary of the invention
It is an object of the invention to overcome disadvantage mentioned above, a kind of heat dissipation problem that can solve inverter module, significantly is provided
The failure for reducing inverter, a kind of underwater electromechanical equipment inverter that can be worked long hours in deep-sea.
The technical scheme is that filling submergence submergence in the existing hollow cylindrical pressure-resistant seal container with end cap
The insulating properties heat-conducting liquid medium of IGBT module.The heat that these insulating properties heat-conducting liquids generate when IGBT inverter module works
It conducts to the barrel of pressure vessel, then distributed by the barrel of pressure vessel into external water, to guarantee IGBT inverter module
It works normally without overheating.The insulating properties heat-conducting liquid is generally insulating properties mineral oil, such as transformer oil, normal hydraulic oil
Deng being also possible to other non-corrosive insulating properties organic liquids, such as ethyl alcohol, glycerine.
Since inverter module heat dissipation problem is resolved, inverter is enable to work long hours at deep-sea, makes to occur because of overheat
A possibility that failure, is substantially reduced, and works more safe and reliable.
Detailed description of the invention
Fig. 1 is inverter body construction schematic diagram；
Fig. 2 is general structure schematic diagram of the present invention.
Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment shall fall within the protection scope of the present invention.
In conjunction with attached drawing 1: the component on inverter ontology 13 includes the two-tube inverter module 12 of three IGBT, power supply and driving
Two-in-one circuit board 17, control circuit board 18, the interpolar small capacitances 26 in 24, three IGBT modules 12 of Hall flow element plate,
Big filter capacitor and its charging resistor 10 and short-circuiting contactor 9, direct current major loop contactor 25 etc..The above element is reasonable
It is mounted on an elongated cylindrical mounting rack, mounting rack is by the round aluminium sheet 16 of four piece of two end trough of belt, round nylon sheet 14, logical
Cross four root long bolts 23, the fixation of nut 22 forms, mounting rack top center is equipped with a nylon rod 7 with holes.Four piece of two end band
The round aluminium sheet of slot be two ends it is one piece each, it is another two pieces separate middle part.
In conjunction with attached drawing 2: inverter ontology 13 is encapsulated in hollow cylindrical pressure-resistant seal container 19, cylindrical pressure-resistant seal
Container is made of hollow cylindrical cylinder 20 and the end cap at both ends 4, uses twice " O " between end cap 4 and hollow cylindrical cylinder 20
Shape sealing ring 5 reliably seals, then is interconnected and fixed with stainless steel bolt 21.The mechanical strength of container entirety can resist specified water
Deep pressure, and pass through pressure test in special pressure testing equipment.When inverter ontology is fitted into container, first in container
Bottom pads upper round rubber plate 15 and is used as vibration isolator, is inserted into inverter ontology, then covers upper one properly on top nylon rod 7
Diameter and the spring of length 6, then upper end cover is covered, inverter ontology is fixed by upper end cover by spring 6, and nylon rod 7 rises
The effect felt relieved and be dielectrically separated from for spring correcting.Transformer oil or normal hydraulic oil are filled in container as insulating heat-conductive liquid
Medium 11, but be not necessarily intended to be completely filled with, it at least can only submerge IGBT module.
Seven are evenly distributed on an end cap wherein through screw hole, wherein being respectively equipped with a single in five screw holes
Watertight cable socket 2；Two in this five sockets 2 input for direct current, and the other three is exported for three-phase alternating current；There are one
One 16 core watertight cable socket 1 is installed in screw hole；Socket 1 is output and input for inverter measurement and control signal.Another
Screw hole is located at the center of end cap 4, and venthole when as dismounting end cap is usually blocked with screw plug, when necessary may be used
For installing spare watertight socket.It is connected between inverter and socket 1,2 by the conducting wire 8 of oil resistant foreskin.Wherein oil resistant packet
The conducting wire 8 of skin is connected on five single sockets 2 on end cap 4.Since this inverter uses line traffic control mode, therefore its control circuit
Corresponding control on plate 18 is connected to 16 core watertight electricity on end cap 4 with output quantity terminal by the thin wire 8 with oil resistant foreskin
