Abstract

低噪声镇流器,其特征在于用石英砂和不饱和树脂混合后的胶着物作填料,填料在壳体内留有空间,并在有空间的壳体上打有2-30只孔。本实用新型的优点:应用本实用新型的低噪声镇流器,具有良好的散热作用,避免烧损;石英砂和不饱和树脂混合后的胶着物不受高温影响,固定可靠,从而减少噪音。

Description

低噪声镇流器
本实用新型涉及一种镇流器,尤其适用于电感式镇流器。
传统的电感式镇流器,将矽钢片及线圈放置在壳体内,用熔融的沥青作填料,使矽钢片及线圈固定在壳体内。这种结构的镇流器,沥青充满整个壳体,没有散热作用,易烧损;沥青的固定作用小,特别是遇到环境温度高或镇流器本身发热,沥青会软化甚至外溢,失去填料的固定作用而产生噪声。
本实用新型的目的是为了克服上述不足之处而提供一种低噪声镇流器。它具有散热作用,避免烧损;即使环境温度高或镇流器本身发热,填料也具有良好的固定作用,因而噪音低。
本实用新型的内容叙述如下:矽钢片及线圈放置在壳体内,用石英砂和不饱和树脂混合后的胶着物作填料,使矽钢片及线圈固定在壳体内。填料在壳体内留有空间,并在有空间的壳体上打有2-30只孔,使壳体内的空间和外界空气流动,具有散热作用。
附图说明:
图为本实用新型的低噪声镇流器的结构示意图。图中1-线圈,2-矽钢片,3-盖,4-孔,5-填料,6-壳体,7-引出线。
实施例是这样作出的:矽钢片(2)及线圈(1)放置在壳体(6)内,用石英砂和不饱和树脂混合后的胶着物作填料(5)。石英砂和不饱和树脂的混合比为1∶0.2-0.8。填料(5)在壳体(6)内留有空间,空间为壳体内腔的15-50%,并在有空间的壳体(6)上打有2-20只孔,孔径Φ3毫米。使壳体(6)内的空间和外界空气流动。
本实用新型的优点:应用本实用新型的低噪声镇流器,具有良好的散热作用,避免烧损;石英砂和不饱和树脂混合后的胶着物不受高温影响,固定可靠,从而减少噪音。
