根据矿山生产的实际情况,我们设制了KPJF型无触点控制器,供控制J型深井泵或JQ型潜水泵应用,效果较好。和同系列其它无触点控制器相比,该型控制器线路简单,可靠性高,不受负荷大小变化的影响,且不需专门强迫风冷的设施(利用井巷自然通风即可)。与有触点控制器比较,该型控制器突出优点是主回路无触点,通断强电力时无火花,动作迅速,寿命长,尤其适用于防爆、防潮及电力通断次数频繁的场合。现将KPJP型无触点控制器的控制原理及结构等介绍如下。 (一)控制原理及动作过程 KPJF型无触点控制器分为手动KPJF-100/900M型和自动KPJF-200/900A型两种。符号意义解释如下: KP——双向可控硅无触点开关装置; J——用于J型(包括SD型)深井泵或JQ
According to the actual situation of mine production, we have set up a KPJF non-contact controller for the control of J-type deep well pump or JQ submersible pump, the effect is better. Compared with other non-contact controllers in the same series, this type of controller has the advantages of simple circuit line, high reliability, no change of load size, and no special forced air-cooled facilities (natural ventilation in the roadway can be used). Compared with the contact controller, this type of controller prominently has the advantage of no contact of the main circuit, no spark when the power is on and off, quick action and long service life, and is especially suitable for occasions where the number of explosion-proof, moisture-proof and power on-off frequently. Now KPJP non-contact controller control theory and structure are described below. (A) control principle and the action process KPJF non-contact controller is divided into manual KPJF-100 / 900M type and automatic KPJF-200 / 900A type two. The symbolic meaning is explained as follows: KP - triac non-contact switching device; J - for J type (including SD type) deep well pump or JQ
