GN27-40.5C穿墙型户内隔离开关价格

Summary

GN27-40.5 indoor high voltage disconnector is a new product. Applicable to the rated voltage of 40.5 kV, 50 Hz AC power system, in the case of voltage and no load, split and close circuit, is designed to replace the old products and production of replacement products. It can be matched with high voltage switchgear or used alone. Use CS6-2 operation mechanism. All of them adopt reinforced insulation design, which can meet the requirements of

The design is scientific, reasonable and novel; multi-contact, rotary contact, self-cleaning ability is good, and heat dissipation ability is improved; the contact point is small in two sides, the contact pressure is large, and easy to adjust; the use of large crawl distance, strengthening insulation ability and withstanding voltage all meet the highest requirements; the installation of bearings on the rotating shaft improves the service life and easy operation.

The series disconnectors are three-phase common chassis structure with vertical rotating knife. The static contacts on the fracture side are designed as swing multi-contact contacts, which have the advantages of low contact pressure, low wear, large heat dissipation area and small operating moment. At the same time, they adopt large climbing distance post insulators and pull rod insulators, with high insulation performance and high mechanical strength. In order to meet the needs, the design of flat-mounted, wall-piercing, with grounding knife and other types. The series disconnectors can be installed horizontally, vertically or obliquely.

概述
GN27-40.5型户内高压隔离开关是一种新型产品。适用于额定电压40.5kV，交流50Hz的电力系统中，在有电压无负载情况下分、合电路之用，是替代老产品而设计生产的换代产品。可与高压开关柜配套，亦可单独使用。配用CS6-2操作机构。均采用加强绝缘设计，可满足‖级污染场所条件下使用。

设计科学、合理、结构新颖；多触点，旋转式接触，自清扫能力好，提高散热能力；接触点在两个面内，操作力矩小，接触压力大，易调整；采用大爬距，加强绝缘能力、耐受电压均满足最gao要求；在转轴上加装轴承，使用寿命提高，操作轻便。GN27-40.5C穿墙型户内隔离开关价格

该系列隔离开关为垂直转动闸刀式三相共底架结构。断口侧静触头设计成摆动式多触片触头，具有单片触头接触压力小、磨损低、散热面积大、操作力矩小等优点，同时采用大爬距支柱绝缘子和拉杆绝缘子、具有高绝缘性能和高机械强度。为满足需要，设计有平装型、穿墙型、带接地刀等型式。该系列隔离开关可以水平、垂直或倾斜安装。GN27-40.5C穿墙型户内隔离开关价格
