Description：

JSY-11S surge arrester counter jin daɗi wurin da ake amfani da ita don rufe kowane lokacin da lightning arrester yake yi aiki a kan series. Ana iya amfani da shi a lightning arrester na grade mai fi 220KV. Tsari na yanayin amfani da shi ce ta sama da lightning arrester da ake taka. Ba a zama da muhimmanci a wurare da cuta ko ci gaba. Ana amfani da zinc oxide varistor kuma ana samu karfin cikakken aiki.

Using conditions:

• Ana iya amfani da shi a kan waje ko fitar.

• Tsari na hawa (-40 to +40) C . 

• Altitude ba zan iya fi 2000m.

• Supply frequency (48 to 62) Hz.

• Babu wuri da ci gaba.

Structure and characteristic:

Electric Principle:

• Discharge counter yana da muhimman komponants kamar sampling varistor, silicon bridge rectifier, high-voltage condenser da electromagnetic counter, etc. Discharge current na lightning arrester yana janar da voltage a kan varistor (nonlinear resistance), kuma yana sha'awar da condenser through silicon bridge rectifier da kuma discharge to electromagnetic counter. Counter yana rufe kowane lokacin da yake discharge, saboda haka yana iya rufe kowane lokacin da lightning arrester yake yi aiki.

•  Enclosure na wannan product yana amfani da premium stainless steel enclosure. Yana da kyau a halin rot resistance da sealing property, ba zan iya canzawa tsari na waje. Inner components suna da kyau a halin ageing resistance, kuma suna iya yi aiki a kan electric power system zuwa lokacin da ya fiye.

JSY-11S lightning arrester discharge counter yana amfani da dual pointer display. Display yana da kyau a halin clear display da easy observation, etc. Counting cycle index yana nuna 0 to 999, wanda yana cewa 1000 times for a cycle. Yana taimakawa don rufe kowane lokacin da lightning yake yi aiki a kan lightning arrester a kan lokacin da ya fiye.

Main Technical Properties:

Product implementing standard: JB/T 10492-2011 Monitoring Device for Metal Oxide Lightning Arrester. The main technical properties are as the below table:

Inspection and acceptance & installation:

 Inspection and Acceptance:

•  A lokacin da ake buƙata products, ake buƙace packing case kuma ake buƙata idan accompanying documents (operation manual,packing list and certificate of approval) su daɗi.

•  Ake buƙata idan accessories su daɗi a kan packing list. A nan, ake buƙata idan appearance na product yana da scrape da kuma idan insulator yana da crack da dropped piece.

A lokacin da ake fitar, dig angle between the plane of the panel of counter and the horizontal plane yana da kyau a kunna 85° , saboda haka don saukar da waterlogging influencing observation. Amfani da M10 bolts don fitar metal enclosure base to the metal support kuma connect the ground through the ground bus. (The monitor base can also be the ground bus.) Another end connects the electrode through the top of the insulator and connects the low-pressure end of the lightning arrester by wire (or aluminum strip). It must install securely and contact reliably.(Installation dimension please see the attached drawing.)

Test methods:

A lokacin da users suka samu products, suka iya amfani da the below methods don test the products.

• Operation Performance Test: Connect a condenser with withstand voltage over 500V and capacity over 5MFD to a 500V megger. Rotate the megger with the rotate speed of 90 to 120 per minute to charge the condenser. When the voltage of the condenser is monitored to be 300V by universal meter, disconnect the condenser connecting with the megger. Use the condenser to discharge the counter instantaneously and the discharge counter should count it as once. Perform it for 10 times consecutively and they should be reliable operations.

• The test of discharge counter can also be performed by the specialized tester produced by our factory. For details please see Instruction of JCQT6000 Lightning Arrester Monitor Tester.

Precautions:

• After putting the discharge counter into operation, operators on duty shall keep monitoring it and record the reading of the discharge counter regularly, so as to master the times of lightning current going through the lightning arrest.

• Note to not overstress on the insulator to avoid destroying the sealing. Meanwhile, users can not take apart the lightning arrester discharge counter casually.

Quality assurance:

On the condition of user using and installing the product according to regulations, the company is responsible for the “Three Guarantees” after-sales service within the period of “Three Guarantees”. The period of “Three Guarantees” is a year. If user has special requirements, he can come and mail for negotiation.

Schematic Diagram of Structure and Installation

How does a surge arrester counter work?

When a surge current (such as overcurrent caused by lightning) passes through the surge arrester, the arrester operates to divert the surge current into the ground. At the same time, the current sensor in the connected surge arrester counter detects this current signal. The signal generated by the sensor is then converted and processed by the signal processing circuit. After processing, the signal triggers the counting unit to increment the count, causing the displayed number to increase by one, indicating that the arrester has performed one operation.
