Problems solved by technology

The traditional cast bus bar is a three-phase cast integrated structure. Products with low voltage levels do not need casings, that is, no magnetic field shielding; products with high voltage levels usually have metal casings, but the metal casings seal the three-phase conductors together, which is equivalent to The traditional common-box enclosed busbar structure has a weak magnetic field shielding effect of the metal shell

Embodiment Construction

[0042] In order to make the object, technical solution and advantages of the present invention clearer, the implementation manner of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0043] see Figure 1 to Figure 3 As shown, the embodiment of the present invention provides a metal casing pouring busbar, which includes: a plurality of standard unit sections 1; 1 combo linked together.

[0044] Among them, see figure 1 As shown, any standard unit segment 1 includes: an inner conductor 10 , a metal shell 11 and an intermediate insulating layer 12 . The metal shell 11 is sleeved on the outer side of the inner conductor. Preferably, the axis of the metal shell 11 coincides with the axis of the inner conductor 10 , and the length of the metal shell 11 is equal to the length of the inner conductor 10 . The mixed insulating material is poured between the inner conductor 10 and the metal shell 11 to form the intermediat...

Abstract

The invention discloses a metal shell cast bus and a method for manufacturing the metal shell cast bus. The metal shell cast bus comprises a plurality of standard unit sections and a connecting assembly. Each standard unit section comprises an inner conductor, a metal shell and a middle insulation layer. The connecting assembly comprises an inner connecting assembly body, an outer connecting assembly body and a middle connecting insulation layer. In addition, the invention further discloses the method for manufacturing the metal shell cast bus. According to the technical scheme, assembling of the metal shell cast bus is made to be more convenient, the design and production period is greatly shortened, and the cost is saved. Moreover, the outer connecting assembly body in the connecting assembly serves as a die and can also bear mechanical stress, demolding is not needed during insulation material casting, the metal shell cast bus can be grounded in use, and operation is safer and more reliable.

Description

technical field [0001] The invention relates to the field of metal-enclosed busbars in power transmission systems, in particular to a metal-cased cast busbar and a manufacturing method thereof. Background technique [0002] Metal-enclosed busbar products are indispensable basic equipment in power transmission systems. They connect generator outlets with transformers, circuit breakers, and transformer cabinets, and are widely used in various power plants and substations such as hydropower, thermal power, wind power, and nuclear power. And the power distribution system of large industrial and mining enterprises. [0003] Traditional products are mainly divided into two categories: common box closed busbar and offline closed busbar. The former is mainly used in small-capacity units and plant branch circuits, while the latter is mainly used in large-capacity units and main circuits. These two categories of products have various branches and improved products respectively, and t...
