DETAILED DESCRIPTION

[0030] The present invention will be further described below with reference to the accompanying drawings.

[0031] like Figures 1-15 As shown, the upper cabinet 1 on the wind turbine side and the lower cabinet 2 on the submarine cable side are connected by screws 4 and nuts 5. The front sides of the upper cabinet 1 on the wind turbine side and the lower cabinet 2 on the submarine cable side are fixed with clamping columns 101 facing both sides and nut columns 102 facing the front side. Right-angle clamping grooves 103 are provided on both sides of the cabinet door 10 to cooperate with the clamping columns 101. The front of the cabinet door 10 is provided with mounting holes 104. The mounting holes 104 of the cabinet door 10 are fixedly connected to the nut columns 102 by screws. The top of the upper cabinet 1 on the wind turbine side is hinged with an arcing cover plate 121, and the rear side of the lower cabinet 2 on the submarine cable side is fixed with an arcing channel 3. The top of the arcing channel 3 is hinged with an arcing cover plate 2 122, and the side of the arcing channel 3 is provided with an arcing baffle 32. The rear sides of the upper cabinet 1 on the wind turbine side and the lower cabinet 2 on the submarine cable side are provided with an inner lining reinforcement ring 19.

[0032] A current transformer fixing frame 13 is provided on the inner side of the top of the upper cabinet 1 on the wind turbine side, U-shaped reinforcement ribs 14 are fixed on both sides of the inner part of the upper cabinet 1 on the wind turbine side and the lower cabinet 2 on the submarine cable side, the cabinet wall lining plate 18 is fixedly connected to the U-shaped reinforcement rib 14, the cabinet wall lining plate 18 is provided with an inner wall fixing horizontal bar 181, the inner wall fixing horizontal bar 181 of the upper cabinet 1 on the wind turbine side is provided with a current transformer bottom support 1811, and a lightning arrester fixing frame 201 is installed on the bottom of the lower cabinet 2 on the submarine cable side.

[0033] The cabinet wall lining plate 18 is provided with a cable clamp fixing frame 182 and a secondary component fixing horizontal bar 183.

[0034] The inner wall fixed horizontal bar 181 is provided with a data frame 1812 and a heating plate shell 1813 .

[0035] A U-shaped punched reinforcement rib 20 is provided at the bottom of the lower cabinet 2 on the submarine cable side, and the lightning arrester fixing frame 201 is installed on the U-shaped punched reinforcement rib 20.

[0036] A cable external fixing angle steel 11 is provided on the outer side of the top of the fan side upper cabinet 1 .

[0037] Reinforcement ribs 15 are fixedly connected between the side and bottom, and between the side and top, of the upper cabinet 1 on the wind turbine side and the lower cabinet 2 on the submarine cable side.

[0038] The upper cabinet 1 on the wind turbine side and the lower cabinet 2 on the submarine cable side are both provided with grounding copper busbar fixings 16 and cabinet external grounding blocks 17 .

[0039] A support frame 31 is provided at the bottom of the arcing channel 3 .

[0040] When the utility model is used, the screw rod 4 passes through the bottom of the upper cabinet 1 on the wind turbine side and the top of the lower cabinet 2 on the submarine cable side, and then two nuts 5 are used to lock the screw rod 4 with the bottom of the upper cabinet 1 on the wind turbine side and the top of the lower cabinet 2 on the submarine cable side from both sides.

[0041] When installing the cabinet door 10, first insert the card column 101 into the right-angle card slot 103, with one end of the right-angle card slot 103 facing up. When the cabinet door 10 moves to the top of the card column 102 at the right-angle card slot 101, the installation hole 104 of the cabinet door 10 is aligned with the threaded hole of the nut column 102. The cabinet door 10 is locked with the nut column 102 by screws.

Only space for personnel operation is required, which can save the use space of the cable compartment.

[0042] An arcing cover plate 121 is directly installed on the top of the upper cabinet 1 on the wind turbine side. When the upper cabinet 1 on the wind turbine side arcs, the arcing cover plate 121 is hingedly rotated upward to release pressure, and the space used is small. Since the lower cabinet 2 on the submarine cable side is directly opposite the upper cabinet 1 on the wind turbine side, an arcing channel 3 is installed on the rear side. An arcing baffle 32 is installed on the upper side of the arcing channel 3 as an extension of the upper side of the arcing channel 3. The top of the arcing channel 3 is hinged with an arcing cover plate 122. When the lower cabinet 2 on the submarine cable side arcs, the arcing cover plate 121 is hingedly rotated upward to release pressure.

The height of the arcing channel 3 is lower than that of the lining reinforcement ring 19.

[0043] U-shaped reinforcement ribs 14 can be installed inside the upper cabinet 1 on the wind turbine side and the lower cabinet 2 on the submarine cable side to strengthen the strength of the cabinet body and are used to install the cabinet wall lining plate 18. The cabinet inner reinforcement ribs 15 are right-angled and are used to strengthen the connection strength between the inner panels of the cabinet body. The cabinet wall lining plate 18 can strengthen the strength of the cabinet body, and components can be set as required on the inner wall fixed horizontal bar 181 of the cabinet wall lining plate 18. The current transformer can be installed through the current transformer fixing bracket 13 and the current transformer base 1811. The U-shaped perforated reinforcement ribs 20 are set at the bottom of the lower cabinet 2 on the submarine cable side to strengthen the bottom strength of the lower cabinet 2 on the submarine cable side, and are used to install the lightning arrester fixing bracket 201 to facilitate the installation of the lightning arrester.

[0044] The grounding copper busbar fixture 16 and the cabinet's external grounding block 17 are used for grounding. A document box 1812 can be placed on the inner wall fixed rail 181 for convenient work. The heating plate housing 1813 is used to mount the heating plate 1811 to maintain a suitable operating temperature within the cabinet. The secondary component fixing rail 183 facilitates further functional expansion. The cable clamp bracket 182 is used to organize cables.

[0045] The top outer side of the fan side upper cabinet 1 is provided with a cable external fixing angle steel 11 for fixing the external cables on the top. A support frame 31 is provided at the bottom of the arcing channel 3 to support the arcing channel 3 independently.
