For better effect, all be provided with side splint 4 on two sides around main body frame 2 is inside, the both sides of intermediate bottom 6 all clamp two between the side splint 4, it is right intermediate bottom 6 carries on spacingly and leads, further guarantees the intensity and the stability of its structure.

For better effect, the transversal L type that personally submits of sealed baffle 32, the top surface folded plate of sealed baffle 32 passes through the effect of pressure spring 31 support press in the bottom surface of landing slab 22, the side folded plate of sealed baffle 32 with intermediate bottom 6's side sliding contact, simple structure is reasonable, can effectively keep apart handcart room 17 rather than the below space, and is convenient high-efficient.

According to the armored open type indoor alternating current metal closed switch equipment, the side partition plate 5 is arranged, the main ventilation pipe 3 is arranged between the main ventilation pipe 3 and the left side wall plate of the main body frame 2, the main ventilation pipe 3 is communicated with the bus chamber 12, the instrument chamber 13, the handcart chamber 17 and the cable chamber 30 through the upper ventilation pipe 10, the first spray pipe 11, the second spray pipe 14, the third spray pipe 16 and the fourth spray pipe 7, and according to monitoring of the temperature in each chamber, inert gases with different temperatures can be introduced into the main ventilation pipe 3 through each spray pipe at any time so as to quickly and effectively control the temperature in the main ventilation pipe, guarantee stable operation of the equipment and be convenient and efficient; the middle partition plate 6 is connected with the upper clamping plate 8 and the lower clamping plate 27 in a sliding manner, is supported by the first lifting rod 28 through the left support plate 29 and the right support plate 25, can adjust the position of the middle partition plate in the height direction as required to change the height position of the cambered plate 18 on the middle partition plate so as to adapt to different contact positions, and simultaneously adjusts the height of the platform plate 22 through the second lifting rod 23 so as to adjust the height of a handcart 19 on the middle partition plate so as to adapt to different types of handcarts 19, is matched with the first lifting rod 28, can adapt to different types of functional trailers so as to expand the functions of the handcart, and the first motor 38 can drive the first screw rod 34 to rotate through the driving gear 36 and the driven gear 37 so as to drive the upper cambered plate and the lower cambered plate to be separated or folded so as to seal and press the contacts conveniently and quickly; a guide rod 26 is arranged in a sleeve 49 on the right support plate 25 in a sliding mode, the pressure spring 31 is always in a compressed state, the upper support plate 24 on the top of the pressure spring pushes the sealing partition plate 32 to always press the platform plate 22, the isolation between a handcart room and the space below the platform plate 22 is kept, and the safety of the equipment in the using process is guaranteed; the second motor 42 drives the second screw rod 47 to rotate through the driving bevel gear 44 and the driven bevel gear 45, so that the push-pull plate 20 is driven to move along the chute 50 to drive the handcart 19 to enter and separate, and the operation is convenient and fast; the armored open type indoor alternating current metal closed switch equipment is reasonable in structure and convenient to operate and use, a part of internal frame structures can be adjusted according to needs to be adapted to functional handcarts of different types, functions of the handcart can be effectively expanded, the working temperature of the handcart can be effectively controlled, and the adaptability is high.
