1、概述 General introduction

本產(chǎn)品用于交流電力系統(tǒng)中，串聯(lián)在金屬氧化物避雷器下面。是用來記錄避雷器動(dòng)作次數(shù)，監(jiān)測避雷器泄漏電流的一種裝置。

JCQ series Online Monitor records the times of the surge arrester’s actions and monitors the arrester’s leakage current, that is in series of the surge arrester in a.c. system.

本產(chǎn)品內(nèi)部采用優(yōu)異的非線性金屬氧化物電阻片取壓，具有動(dòng)作靈敏可靠，通流容量大，使用電壓等級范圍廣，外形采用不銹鋼材質(zhì)，指示清晰明顯，外形美觀大方，密封性能良好等優(yōu)點(diǎn)，尤其適用于超高壓、大容量電力系統(tǒng)中和強(qiáng)電、多雷、頻繁動(dòng)作的地區(qū)使用。

The interior of the products uses the outstanding non-linear metal oxide resistance to take the pressure, has lots of merits such as the movement keenly and reliable, the current withstand to be big, the Operating voltage rating scope is broad, demonstrated clear obvious, contour elegant appearance, seal good and so on . is suitable especially for the ultrahigh voltage and large capacity power system and the local that strong electricity, the multi-thunder and the frequent action.

本產(chǎn)品使用條件與避雷器相同。

Using condition of this product is the same as surge arrester.

2、產(chǎn)品主要技術(shù)參數(shù) Main technology parameters

JCQ-6型監(jiān)測器增加了表面污穢電流的監(jiān)測功能，污穢表通過避雷器外套底部安裝的屏蔽環(huán)，將屏蔽環(huán)收集的避雷器外套部的污穢電流轉(zhuǎn)化成電導(dǎo)率μS，污穢表表面的彩色刻度可作為變電站污穢等級的參考。

4 用戶須知 User notice

JCQ 系列在線監(jiān)測器在投入運(yùn)行前或運(yùn)行 1～2 年后，應(yīng)進(jìn)行檢測，檢測的項(xiàng)目及方法如下：

The JCQ series Online Monitor should be monitored before running or after for 1~2 years, items and ways are as following:

① 用萬用表測量在線監(jiān)測器高壓出線端對地之間的直流電阻，不應(yīng)有短路、斷路、接觸不良現(xiàn)象。

Measure the D.C. resistance of the Instrument between the H.V. lead terminal and the earth with multimeter, should not exist the tendency conditions: short circuit, open circuit and the ill contact.

② 用 500V 搖表對 600V、10μF 電容器充電，用充電后的電容器對在線監(jiān)測器放電，計(jì)數(shù)器應(yīng)動(dòng)作一次，同時(shí)在線監(jiān)測器的電流表應(yīng)向最大方向擺動(dòng)一次。對于在線監(jiān)測器應(yīng)連續(xù)試驗(yàn) 10 次，均能正確可靠動(dòng)

作，則認(rèn)為該產(chǎn)品動(dòng)作性能良好，否則必須進(jìn)行檢修。

The capacitor for 600V 10μF is charged up by megohm table for 500V, after discharging electricity to the Instrument, the Instrument should act one time, and the amperemeter should move one time. When the counter are tested continuously ten times, acting rightly and reliably, the product is thought that the performance of action is well. Or, it needs examining and repairing.

③ 檢修時(shí)，先用導(dǎo)線將避雷器接地端可靠接地，才能拆下在線監(jiān)測器。

When examining and repairing the Instrument ,ground firstly reliably with the wires, and take down it.

④ 參照本產(chǎn)品外形安裝尺寸圖進(jìn)行安裝，在線監(jiān)測器串聯(lián)在避雷器與地之間。

Referring to mounting dimension drawings and mounting, the Instrument is in series between surge arrester and the earth.

 a. 安裝時(shí)，將在線監(jiān)測器的法蘭用 M10×30 的螺栓固定在避雷器底座附近便于觀察的平視位置上，作為接地端。高壓出線端與避雷器連接。

 When installs, The flange of the Instrument is fixed by the bolts for M10×30 nearby the pedestal observed easily level, which is as the earth. The H.V. terminal and surge arrester are linked.

b. 安裝時(shí)，該產(chǎn)品的高壓端引線拉力不大于 10kg，涂有紅漆的螺栓、螺母不得松動(dòng)，以防破壞密封。

 When mounted, the pull of the H.V. terminal down-lead is not more than 10㎏. Bolts and nuts with red can not become flexible, avoiding to destroy the airproofing.

c. 安裝后檢查在線監(jiān)測器，不應(yīng)有明顯的傾斜。

 Inspect the Instrument after mounting, can not incline obviously.

⑤ 用戶在訂貨時(shí)請按照標(biāo)準(zhǔn)寫清型號(hào)。如有特殊要求，請?jiān)敿?xì)提出。

 Please write the types distinctly according to the standard, when users place an order. Bring forward in detail, if having especial request.

⑥ 產(chǎn)品自發(fā)貨之日起，兩年內(nèi)因質(zhì)量問題而不能使用，我公司負(fù)責(zé)更換或維修。

Our company will replace or repair, if no using because of trouble of the quality in two years from consigning day.
