hl牌螺釘系列的超高壓陶瓷電容已經(jīng)廣泛應(yīng)用于送電、配電系統(tǒng)的電力設(shè)備和處理脈沖能量的設(shè)備中，如：功率補(bǔ)償、限流、濾波、計(jì)量、儲(chǔ)能以及分電壓等產(chǎn)品中。電力系統(tǒng)的特殊*流、高電壓、高頻、處于室外環(huán)境 (-40°c到+60°c)、雷擊、大電流等等，在惡劣環(huán)境，要求電容具有超強(qiáng)的穩(wěn)定性，即變化率要小；同時(shí)，計(jì)量，分電壓等產(chǎn)品要求高精密度，這對(duì)處于這種環(huán)境下的高壓陶瓷電容器的局部放電量有著極為苛刻的要求：局放為3pc-50pc不等。

hl brand screw series ehv ceramic capacitors have been widely used in electrical e and the pulse energy e of power transmission and distribution systems, such as: power compensation, current limiting, filtering, metering, energy storage and sub-voltage products. the particularity of the power system are: ac, high voltage, high frequency, in the outdoor environment (-40°c to +60°c), lightning, high current, etc., capacitors are required to have superior stability in harsh environments, the rate of change is small; at the same time, metering, sub-voltage and other products re high precision, magnitude of partial discharge of high voltage ceramic capacitors in this environment has a very demanding re: pd from 3pc to 5pc.
