FQ series fan special electric control box
Briefing of FQ series fan special electric control box
　 FQ series fan special electric control boxes contain single-speed and double-speed two type electric control boxes, with power from 0.01Kw to 150Kw. It could not only be used to control flow, but also to fan control of fire fighting. (see theory diagram)
Model dimension and theory parameter of ZT fan special rubber damper
According different actuating ways, PQ series fan special electric control box could be divided into directly actuation, Y—△reduced voltage actuation and actuation compensator. Customers should note which actuation way you want, if there is no note, we would consider it as direct actuation. FQ 系列风机专用电控箱 FQ series fan special electric control box 一、FQ系列风机专用电控箱概述 　 FQ系列风机专用电控箱分为单速、双速两种电控箱，功率从0.01Kw-150Kw，电控箱作为一般风控制外，还可作为消防风机控制用(见原理图)。 Briefing of FQ series fan special electric control box FQ series fan special electric control boxes contain single-speed and double-speed two type electric control boxes, with power from 0.01Kw to 150Kw. It could not only be used to control flow, but also to fan control of fire fighting. (see theory diagram) Y circuit, △circuit, diagram one Y and △ circuits of single-speed fan, low speed circuit, high-speed circuit, diagram two fan circuit of double-speed fan Type explanation of FQ series fan special electric control box, power, Ⅰis single-speed, Ⅱis double-speed, fan electric control box, diagram three, aspect of electric control box Model dimension and theory parameter of ZT fan special rubber damper According different actuating ways, PQ series fan special electric control box could be divided into directly actuation, Y—△reduced voltage actuation and actuation compensator. Customers should note which actuation way you want, if there is no note, we would consider it as direct actuation. 1. single-speed fan circuit see diagram one, note: educed voltage actuation is better to be used if motor voltage is more than 11KW. 2. double-speed fan , double speed fan adopts double speed motor. Through changing the motor inside winding connection ways to change motor phase. In the low speed, motor inside winding connects △ or Y , in high speed it connects YY. Joint ways see diagram two 。
