Embodiment Construction

[0017] The resin casting busbar expansion joint of the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0018] As shown in the figure, the resin casting busbar expansion joint of the present invention includes two casting bodies 1 arranged at intervals, two movable side plates 2 that can move longitudinally on the left and right sides of the two casting bodies, and two movable side plates 2 arranged in parallel on the two sides of the casting body. The multi-phase conductors 3 with flexible functions between the pouring bodies. The conductors 3 of each phase pass through the two pouring bodies in turn and are solidified with the pouring bodies. The conductors 3 of each phase extend out of the two pouring bodies 1 respectively to form a connection Terminal 5, each phase conductor 3 is set as a stretchable soft connection (conductor flexible area) between the two sections of cast body, the soft c...

Abstract

The invention discloses a resin pouring busbar telescopic joint comprising two insulating pouring bodies arranged at intervals and multi-phase conductors arranged in parallel between the two pouring bodies. Each phase of conductor successively penetrates through the two pouring bodies and extends out of the two ends of the two pouring bodies respectively. The multi-phase conductors form telescopicsoft connection between the two pouring bodies. The two sides of the two pouring bodies are guided and connected through movable side plates capable of moving longitudinally, and the cavity between the movable side plates and the two pouring bodies is filled with insulating elastic colloid coated outside each soft connection. With application of the structure, the space formed between the two pouring bodies and the two movable side plates is filled with the insulating elastic colloid coated outside each soft connection so that the expansion and contraction are not affected and the insulationand waterproof performance are enhanced, the overall structural design is reasonable, the expansion and contraction reliability is quite good and the service life is greatly prolonged.

Description

technical field [0001] The invention relates to a component structure for busbar connection, in particular to a resin casting busbar expansion joint. Background technique [0002] In power transmission and distribution busbar equipment, when multiple sections of busbars are connected, the connecting parts of the two sections of busbars need to be connected through expansion joints, whose function is to compensate and adjust the thermal expansion and contraction of the busbar during operation, so as to avoid the overall deformation and damage of the busbar. The structure of existing expansion joints used for pouring waterproof busbars usually includes multiple flexible connections installed through guide seats for connecting with the busbar. The existing structure realizes the basic telescopic function, but on the one hand, the flexible connection is directly exposed, and the insulation performance and waterproof performance are poor, which easily causes short-circuit faults ...
