? 使用及維護：Use and maintenance
1、變阻器單臺產(chǎn)品在電路中可作串、并聯(lián)使用，也可多臺并機使用。
Rheostat single products in the circuit can be used for series and parallel use can also be multiple, and machine use.
2、滑線變阻器的結(jié)構(gòu)和符號如圖所示，電阻絲的兩頭分別接在瓷管兩端的A、B接線柱 上，A、B之間的電阻即為總電阻?；瑒宇^D可沿金屬桿滑動，與電阻絲接觸良好，改 變其位置就可以改變AC（或BC）電阻。額定電流和總電阻等參數(shù)均在銘牌上標明。在 電路中有兩種接法：
Slip-line rheostat of the structure and symbols shown in the figure, the resistance wire of the two were connected to the ceramic tube at both ends of A, B terminal on the, A, B shall be the total resistance between the resistor. Sliding head D can slide along the metal bars, with good contact resistance wire, changing its location can change the AC （or BC） resistance. Rated current and the total resistance and other parameters are indicated on the nameplate. In the circuit there are two kinds of access method:
①限流接法：將變阻器的一個固定端和滑動端接入電路，由于電阻可變，從而使電路中 的電流發(fā)生變化。
① limiting Connection: The rheostat on a fixed side and sliding side access to the circuit, due to the variable resistor, so that circuit current change.
②分壓接法：將變阻器的兩個固定端分別與電源的兩極相連，由滑動端和任一固定端連 接到電路。由于電流通過變阻器的全部電阻絲，故A、B之間任意兩點都有電勢差。當 滑動頭移動時，就改變了電路的輸入電壓。
注意：限流接法中，變阻器的滑動頭應(yīng)放在電阻zui大的位置；分壓接法中，變阻器的滑 動頭應(yīng)放在分壓zui小的位置。
② Partial Pressure Connection: The varistor of the two fixed end of the bipolar power supply, respectively connected by a sliding side and either a fixed terminal connected to the circuit. As the current through the varistor all the resistance wire, so A, B are any two points between the electrical potential difference. When sliding the first move, to change the circuit's input voltage.
Note: Limiting access law, rheostat sliding head should be placed on the location of the greatest resistance; sub crimping law, rheostat sliding head should be placed on the location of partial pressure of the smallest.

? 使用條件及注意事項：Conditions of Use and Notice
１、請嚴格保證變阻器在額定電壓及電流值下使用。
please ensure strict rheostat at rated voltage and current values to use.
２、變阻器是易發(fā)熱元件，安裝時不宜靠近不能受熱的物體。

３、變阻器配有M6的安裝孔及接地端子，保證使用時良好的地。
rheostat with M6 mounting holes and grounding terminals to ensure a good grounding when used.
４、變阻器使用如發(fā)生接觸不良時，可在電刷接觸面移動的康銅絲表面，除去氧化絕緣層， 即可消除其現(xiàn)象。
rheostat to use the event of being exposed, it can move in the brush contact surface Kang copper surface, remove the insulating oxide layer, you can eliminate the phenomenon.
６、變阻器經(jīng)長時間的連續(xù)使用后，如發(fā)現(xiàn)滑片失去壓力時，需拆下接觸系統(tǒng)，把接觸橋修 正（矯直），重新裝上后，使電刷貼平于電阻絲表面，方可正常使用。
rheostat through a long period of continuous use, such as the vane was found to lose pressure, the need to remove the contact system to contact the bridge correction （straightening）, re-fitted after, so that resistance wire brush affixed flat on the surface, side can be used normally.

7、安裝場所的空氣中不應(yīng)含化學腐蝕氣體和蒸氣，無爆炸性塵埃。the installation of air spaces should not be included chemical etching gases and vapors, non- explosive dust.
