Embodiment Construction

[0016] In order to deepen the understanding of the present invention, the present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments, which are only used to explain the present invention and do not constitute a limitation to the protection scope of the present invention.

[0017] Such as figure 1 As shown in -2, the integrated capacitive arrester disconnector assembly provided in this embodiment includes a surge arrester, an insulating mounting bracket, and a disconnector, and the disconnector is fixed on the insulating mounting bracket and includes a connecting terminal 1 and a grounding terminal 2. The lightning arrester is conductively connected to the connecting terminal 1, the grounding terminal 2 is grounded, and a grading component 3 and a discharger 4 are arranged in parallel between the connecting terminal 1 and the grounding terminal 2. The discharger 4 An explosion sleeve 5 is arranged at the place where...

Abstract

The invention discloses an integrated capacitive arrester disconnector assembly. The integrated capacitive arrester disconnector assembly comprises an arrester, an insulation installing support and a disconnector. The disconnector is fixedly arranged on the insulation installing support and comprises a connecting end and a grounding end, the arrester is conductively connected with the connecting end, and the grounding end is connected to the ground. A grading assembly and a discharger are arranged between the connecting end and the grounding end in parallel, an explosion sleeve is arranged at the electric arc generation position of the discharger, and the grading assembly is a capacitor. Compared with a traditional split type resistance type disconnector, the integrated capacitive arrester disconnector assembly is reliable in motion, and the transient overvoltage inhibiting capacity is remarkably improved. In addition, due to the integrated design, heat conduction is more direct and quicker in the short-circuit process, and the disconnector is shorter in motion time limit.

Description

technical field [0001] The invention relates to the technical field of disconnectors for arresters, in particular to an integrated capacitive arrester disconnector assembly. technical background [0002] At present, most of the distribution-level surge arresters do not have disconnector components or need to be purchased and installed separately, and resistors are used as disconnector classification components. Although its performance can meet the requirements from the test verification results, problems frequently occur in the actual use process, and there are often vicious accidents such as failure to reliably disengage from the fault arrester, resulting in local short-circuit tripping of the line. [0003] Surge arresters are the most effective means to protect lines or equipment from overvoltage, operation shocks and lightning shocks, and are the basis for the insulation and coordination of the entire system. The existing power distribution arrester is usually a gaples...
