Submersible fuel-filled tank with compensating ground pins and method of operation

Abstract

A submersible fuel-filled tank body with compensation ground pins and an operation method thereof, comprising a plurality of fuel tanks stacked up and down in sequence, two adjacent fuel tanks are an upper fuel-filled fuel tank and a lower fuel-filled fuel tank, the upper fuel-filled fuel tank A through hole is opened on the bottom surface of the through hole, and a pin is installed in the through hole through a sealing ring. The top surface of the needle is installed with a common ground wire through a compression nut; the structure of the pin is: including a casing, the middle of the casing is provided with an inner cone surface, the upper part of the inner cone surface is the upper inner hole, and the lower part of the inner cone surface is It is a lower inner hole, a thimble is fitted in the lower inner hole, the top surface of the thimble is matched with the inner cone surface, the thimble slides up and down along the lower inner hole, the top surface of the thimble is abutted with a sealing plug, and the shell The top of the body is fitted with a cap, and in the upper inner hole, a spring is installed between the sealing plug and the cap, which is easy to operate and reliable.

Description

technical field [0001] The invention relates to the technical field of auxiliary equipment for oil-filled tanks, in particular to a submersible oil-filled tank with compensation ground pins and an operation method thereof. Background technique [0002] The electrical system of the submersible has many equipment and complicated wiring. In many occasions, the junction box is used as the transfer station for the connection of the various equipment of the submersible. In order to reduce the difficulty of designing the junction box and reduce its weight, the junction box is generally designed to be filled with oil. form of compensation. [0003] With the diversification of submersible functions, a submersible often has 2 to 3 junction boxes, and many even reach 5 to 7. In order to facilitate the centralized arrangement of equipment and reduce the installation volume, it is often necessary to stack the junction boxes. , After the superimposed arrangement, the connection work and ...

Problems solved by technology

[0003] With the diversification of submersible functions, a submersible often has 2 to 3 junction boxes, and even 5 to 7 junction boxes. In order to facilitate the centralized arrangement of equipment and reduce the installation volume, it is often necessary to stack the junction boxes , after the superimposed arrangement, the connection work and grounding work of the compensation oil between the two adjacent boxes bring difficulties and troublesome operation
