The invention relates to an assembly type building wall T-shaped joint connecting structure. A first rectangular steel bar frame structure, a second rectangular steel bar frame structure and a third rectangular steel bar frame structure are exposed out of the adjacent side portions of a first steel concrete assembly, a second steel concrete assembly and a third steel concrete assembly correspondingly. Side steel bar frame structures are arranged on the two sides of the third steel concrete assembly in an exposed mode, and side supporting cavities for containing the side steel bar frame structures are formed in the first steel concrete assembly and the second rectangular steel bar frame structure. And pouring pieces located in the pouring cavity, the first side supporting cavity and the second side supporting cavity are further included. According to the scheme, extra fixing pieces for auxiliary supporting are not needed during pouring, pouring is convenient, and the construction efficiency is high. And meanwhile, the n-shaped pouring piece is tightly connected and fixed with the first steel concrete assembly, the second steel concrete assembly and the third steel concrete assembly, and high-strength concrete at the high-strength cement blending position is adopted for pouring, so that the strength and the water seepage prevention effect of the T-shaped connecting structure are improved.

The application relates to a high-voltage pulse capacitor electrode leading-out device, belonging to the field of pulses. The device comprises a copper bus, a guide rod, an insulating plate, a sleeve and a box cover, the guide rod and the sleeve penetrate through the box cover, the guide rod is arranged in the middle of the sleeve, the insulating plate is connected with the bottom end of the guide rod, and the copper bus is connected with the bottom end of the guide rod after penetrating through the insulating plate. The application is favorable for shortening the distance between the capacitor box cover and the copper bus, thereby reducing the volume of the capacitor and improving the energy storage density of the capacitor.

The present invention relates to an insulation protection structure for a high-voltage built-in outlet of a large transformer, and belongs to the technical field of transformer manufacturing. The technical scheme is as follows: the high-voltage coil outlet protection structure is to set a high-voltage outlet protection angle ring (8) at the outlet of the high-voltage coil (9), the lower part of the high-voltage outlet protection angle ring (8) is a groove-shaped structure matching the outlet of the high-voltage coil (9), and the upper part of the high-voltage outlet protection angle ring (8) is a sleeve structure matching the high-voltage lead (10); the clamp web protection structure is to set a web protection angle ring (3) on the clamp web (1) near the outlet of the high-voltage coil (9), the lower part of the web protection angle ring (3) is an arc surface, the upper part of the web protection angle ring is a plane, and the lower part of the web protection angle ring is inserted into the body. The beneficial effect of the present invention is that a specially shaped molded insulating part is used to protect the high-voltage coil outlet and the surrounding clamp web, thereby improving the safety performance of the transformer.
