摘要

为了环保

同时解决SF

高压电器设备在低温下可靠运行的问题

研制和应用SF

混合气体的电器设备是非常必要的。而同样压力下的SF

所占比例越高

其密度越大

绝缘能力越强

但节能减排的意义就越小

因此需要研制SF

混合气体密度继电器

用于监测其气体密度

从而既确保高压电器设备安全运行

又能达到较好的节能减排效果。文中提出研制高性能的SF

混合气体密度继电器

并阐述了高性能的SF

混合气体密度继电器的实现方法

以及通过性能测试

证实该SF

混合气体密度继电器具有较好的性能。

Abstract

In order to protect the environment and solve the problem of reliable operation of SF6 high voltage electrical equipment at low temperature

it is necessary to develop and apply the electrical equipment using SF

gas mixtures.Under the same pressure

the larger the proportion of SF6 is

the more the density is

and the stronger the insulating ability is;however

the smaller the energy-saving and emission-reduction significance will be.In order to detect gas density

ensure the safety of the high voltage electrical equipment

save energy and reduce emission

it is important

to develop the density relay of SF

gas mixtures.In this paper

a high-performance density relay of SF

gas mixtures is developed and the way of realization is presented.By the performance testing

it is confirmed that the density relay of SF

gas mixtures has better performance.
