The two ends of the waterproof cable are both provided with aviation connector plugs, and the joint of the waterproof cable and the aviation connector plugs is fully sealed.
And a secondary component is arranged in the secondary control chamber and is connected with an aviation connector plug on the waterproof cable through an aviation connector socket.
The aviation connector socket penetrates through the secondary control chamber and is connected with the secondary control chamber through a screw, and the joint of the secondary control chamber and the aviation connector socket is fully sealed.
The indoor operating mechanism that is equipped with of mechanism, operating mechanism adopt the sealed box of totally enclosed, and operating mechanism passes through double containment dynamic fit structure and is connected with internal switch device transmission, realizes also can sealing when the transmission.
The protection level of the air box chamber is higher than IP67 level, and a switch and a three-phase integrated CT are arranged in the air box chamber.
The air box chamber adopts a full-sealed welding structure.
The cable chamber is internally provided with a wire inlet and outlet sleeve, and the end part of the wire inlet and outlet sleeve is provided with a fully-sealed and fully-insulated cable head.
And the dry gas in the secondary control chamber and the mechanism chamber is a gas formed by mixing nitrogen and oxygen.
Has the advantages that: compared with the prior art, the utility model, its beneficial effect lies in: (1) the problem of condensation of a mechanism room and a secondary control room in the conventional power grid system is solved, and the overall performance of the ring main unit equipment is improved; (2) the power supply device can normally supply power within 10m underwater, and can also be normally used in regions with severe environment, humid climate or frequent flooding, thereby avoiding the phenomenon of large-area power failure.

Detailed Description
The present invention will be described in further detail with reference to the following detailed description and the accompanying drawings.
As shown in fig. 1 and 2, the utility model discloses a secondary control room 1, electrified display 2, mechanism room 3, many waterproof cables 4, gas tank room 5, the integrative CT6 of three-phase, cable chamber 7, many waterproof cables 4 are connected secondary control room 1, mechanism room 3, gas tank room 5, and waterproof cable 4 both ends all are equipped with the aviation connector plug to the junction full-sealing of waterproof cable 4 and aviation connector plug. And a secondary component is arranged in the secondary control room 1 and is connected with an aviation connector plug on the waterproof cable 4 through an aviation connector socket. In the embodiment, the aviation connector socket penetrates through the secondary control room 1 and is connected with the secondary control room 1 through a screw, and the connection part of the secondary control room 1 and the aviation connector socket is sealed completely. An operating mechanism is arranged in the mechanism chamber 3, the operating mechanism is sealed by a fully-sealed box body, and the operating mechanism is in transmission connection with the internal switch device through a double-seal dynamic matching structure. The gas box chamber 5 is provided with a switch and a three-phase integrated CT 6. The gas box chamber 5 adopts a full-sealed welding structure. A wire inlet and outlet sleeve is arranged in the cable chamber 7, and a fully-sealed and fully-insulated cable head is arranged at the end part of the wire inlet and outlet sleeve.
The secondary control chamber 1 and the mechanism chamber 3 are filled with dry gas, in this embodiment, the dry gas is a mixture of nitrogen and oxygen, wherein the content of nitrogen is 78%, and the content of oxygen is 22%. The protection grades of the secondary control room 1, the charged display 2, the mechanism room 3, the waterproof cable 4 and the air box room 5 are all above IP67 grade, wherein the protection grade of the air box room 5 is IP68 grade.
