Abstract

本开关为一种电器调压节能开关。由抑制高次 谐波电路、过压抑网络、移相器、触发控制电路和短路 自动保护电路构成。与负载串联连接,可使电压在 30~260V范围内可调,且由于起动电压低,有效地阻 止了对负载冷低阻值的大电流冲击,延长了负载使用 寿命。同时又节约了电能。

Description

本实用新型涉及一种电器开关,特别是一种调压开关。
目前,办公、住宅常用电器开关,特别是安装于墙壁的用来控制电灯、电扇的开关,其起动电流较大,易损坏电器。目前一些具有调速功能的电扇开关,多为2~6个档位,其结构复杂,体积大,且易损坏,使控制失灵。
本实用新型的目的是提供一种起动电压低、且可随意调节电器速度、亮度、温度的节能开关。
本实用新型由抑制高次谐波电路、过压抑制网络、移相器、触发控制电路和短路自动保护电路构成。其抑制高次谐波电路由电感L和电容C1组成,过压抑制网络由电阻R1和电容C2组成,移相器由电阻R2、电容C3及可调电阻W1、W2组成,触发控制电路由触发二极管D1和可控硅D2组成,短路自动保护电路由压敏电阻R3构成。K1为全电压开关,K2为调压开关。
图1为本实用新型外形图
图2为本实用新型电路图
本开关与负载串联连接。当开启全电压开关K1时,照明灯亮,但不能调光。关闭K1,开启调压开关K2,调节W1,开启时,灯炮两端电压为30V,然后逐渐按顺时针方向旋转W1,由R2、C3、W1、W2组成的移相器不断改 变可控硅D2的导通角,使相位不断发生变化,电压从30~260V范围内可调,灯炮由暗变亮。本开关与电扇连接,可使风速由慢变快。与电热器连接,可使温度由低变高。且由于起动电压低,有效地阻止了对电器设备冷低阻值的大电流冲击,延长了电器的使用寿命,同时节约了电能。
本实用新型外型美观、结构简单、使用方便安全。
