Respectively indicate in figure: 1-oil pressure compensates housing, 2-counterbalance spring, 3-compensating piston, 4-end cap, 5-transformer mount pad, 6-transformer, 7-housing, 8-power input socket, 9-oil-filled joint, 10-steam vent, 11-power output socket.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in further detail:
As shown in Figure 1, oil pressure compensates housing 1 and is fixed on end cap 4 by screw mode, counterbalance spring 2, compensating piston 3 is arranged on oil pressure and compensates housing 1 inside, counterbalance spring 2 one end is supported on compensating piston 3, the other end is supported on oil pressure and compensates on housing 1, one end of compensating piston 3 and contact with sea water, the contact of hydraulic oil in the other end and seal chamber, compensating piston 3 is provided with sealing ring, realize inner with outside completely isolated of seal chamber, transformer (6) is installed on transformer mount pad 5 by bolt, end cap is installed to by bolt again after becoming to be integrated) on.
As shown in Figure 2, end cap 4 there is also mounted power input socket 8, oil-filled joint 9, steam vent 10 and power output socket 11, steam vent 10 is arranged on end cap top, and during to ensure oil-filled, the position of steam vent 10 is in highest point, facilitates unnecessary removal of bubbles.The terminals of power input socket 8 are connected with the input of transformer by wire, and the terminals of power output socket 11 are connected with the output of transformer by wire.Oil-filled joint 9 is one-way sealing joint, facilitates by oil-filled kettle inside transformer cavity and compensator housing carry out oil-filled under water.
As shown in Figure 1, by install all component, part, sealing ring end cap 4 be arranged in housing 7 by the mode of screw.
As shown in Figure 1 to Figure 2, after transformer installation under water, the steam vent 10 of fetching boiling water on lower transformer end cap 4, give in seal chamber oil-filled with oil-filled kettle by oil-filled joint 15, when fluid reaches the top of steam vent 10, and after guaranteeing all gas discharge in seal chamber, steam vent 10 is blocked, continue oil-filled in seal chamber, compensating piston 3 is by under the effect of seal chamber internal oil pressure, and overcome the spring-force driven dual of counterbalance spring 2, move slowly, until the upper-end contact of compensating piston 3 compensates the spacing end face of housing 1 to oil pressure, compensating piston 3 is mobile by stopping, then the snap joint of oil-filled kettle is extracted, the Oil feeding process of transformer completes under water.At this moment inside transformer pressure is by a little higher than external pressure under water, and pressure differential is the spring force of compensating piston 3.
Two hermetically sealed connectors passing through transformer end cap 4 under water under water when transformer uses connect high undersea hydrostatic pressures service cables and low pressure output cable, deep-sea will be put into by transformer under water, hydraulic oil in oil pressure compensation housing 1 is under the effect of external pressure, be pushed in seal chamber by compensating piston 3, until reach inside and outside pressure balance, along with the increase of transferring the degree of depth, until arrive the working depth of transformer under water, oil pressure compensates the hydraulic oil in housing 1 and is pushed in seal chamber with the change of inside and outside pressure, realize under water transformer under deep-sea inside and outside all press.
After transformer completes underwater operation engineering in deep-sea under water, in the process promoted from deep-sea, the pressure of seal chamber inside is greater than external pressure, the hydraulic oil of seal chamber inside overflows under the effect of internal pressure in seal chamber, promote compensating piston 3 and arrive oil pressure compensation housing 1, thus all pressures of the inside and outside pressure realized.
The utility model has following advantage in a particular embodiment: a kind of even pressure type of this utility model under water transformer achieves all pressures of transformer maximum working depth under water, whole rising and transfer cross claim in, also dynamic response realizes external and internal pressure equilibrium, meets the demand that underwater installation can normally work in whole working depth.
