Specific embodiment
Below in conjunction with attached drawing, detailed description of the preferred embodiments, it should be appreciated that retouches in this place
The specific embodiment stated is merely to illustrate and explain the present invention, and is not intended to restrict the invention.
In the present invention, in the absence of explanation to the contrary, the noun of locality used such as " upper and lower, left and right " is usually needle
For the direction of attached drawing.
As shown in Figure 1, the present invention provides a kind of 330kV and the outdoor oil-filled terminal oiling device of the above cable, with oily terminal
10 are connected by oil fuel tube 6, including rack platform 1, large capacity oil tank 2, heating and heat-insulating device 3, temperature measuring equipment 4,9 and of vacuum pump
Oily terminal support 11, large capacity oil tank 2 are fixed on rack platform 1, and rack platform 1 uses four leg structures, ensure that large capacity
Oil tank 2 is stably placed above；Heating and heat-insulating device 3 includes a heating device and thermal insulated material for covering, which can
To be electric heater etc.；Heating and heat-insulating device 3 is covered on the surface of large capacity oil tank 2, so that the insulating oil in large capacity oil tank 2
Temperature reaches to be kept constant when centainly requiring.Hole is provided on large capacity oil tank 2, temperature measuring equipment 4 passes through on large capacity oil tank 2
Hole is fixedly mounted on large capacity oil tank 2, can measure the temperature of large capacity oil tank 2 interior insulation oil at any time；One end of oil fuel tube 6
Be connected to 2 side of large capacity oil tank by valve a5, the other end is connected to the bottom of oily terminal 10 by valve b7, and with its end
Casing connection is held, oily terminal 10 is fixedly mounted on oily terminal support 11, and is equipped on the pot head at 10 top of oily terminal
Valve c8, and vacuum pump 9 is connected by pipeline, with the operation that can be vacuumized inside the pot head to oily terminal 10.
In addition, as a preferred embodiment, one end of the oil fuel tube 6 is connected to 2 side of large capacity oil tank
Lower part, can guarantee going on smoothly and thoroughly for oiling.
In addition, for operating easily, as a preferred embodiment, valve a5 is close to 2 side of large capacity oil tank
Lower part installation, the valve b7 are installed close to oily 10 bottom of terminal.
The present invention also provides a kind of 330KV and the outdoor oil-filled terminal correction oil injection methods of the above cable, the specific steps are as follows:
Step 1: large capacity oil tank 2 being heated, oil temperature reaches 100 DEG C or so after heating it；
Step 2: closing valve a5, open valve b7, valve c8, open 9 pairs of vacuum pump oily terminals 10 and vacuumize, keep it true
Reciprocal of duty cycle reaches -0.1Mpa；
