Ang mga lightning arrester mao ang core equipment sa power systems para sa pagprotekta labiay lightning overvoltages ug switching overvoltages. Ang maayo nga operasyon sa ilang discharge counters direkta nga determina ang epektibidad sa protective function sa arrester. Kon ang counter magfail, ang maintenance personnel dili makakapahayag og eksakto sa status sa operasyon sa arrester, posible nga magresulta sa seriusong konsekwensiya sama sa equipment breakdown ug power outages.

Ang WDFJZ-V Handheld Arrester Discharge Counter naghandog og epektibo ug precise nga solusyon alang sa testing ug maintenance sa arrester discharge counters, pokus sa apat ka aspeto: application scenarios, implementation process, core advantages, ug service support, natutudlo sa power companies sa pag-ensure sa safe ug stable operation sa grid.

​I. Solution Applicable Scenarios​

Ang WDFJZ-V Handheld Arrester Discharge Counter makakaverify sa operational reliability sa iba't ibang tipo sa arrester counters. Kini gipangita sa sumala sa mosunod nga scenarios:

1. ​Regular Power System Inspections​
• ​Substation Arrester Routine Testing:​​ Ang valve-type arresters (kasama ang ordinary silicon carbide valve-type <FZ, FCD>, magnetic blow silicon carbide valve-type <FCZ, FCD>) ug metal oxide arresters sa substation nanginahanglan og quarterly o semi-annual discharge counter operation verification. Kini nga device nagtest kung ang counter makakaincrement ng eksakto sa simulated discharge signals, naaasikaso ang failure sa pagmonitor sa actual arrester discharges tungod sa counter jamming o malfunction, nga posible nga magresulta sa missed fault warnings.
• ​Transmission Line Arrester Inspection:​​ Ang mga arrester sa transmission lines (e.g., line-type metal oxide arresters) exposado sa labaw pa sa outdoor. Naaapektuhan sa environmental factors (e.g., mataas nga temperatura, humidity, lightning strikes), ang counters mas susceptible sa failure. Ang maintenance personnel makamangandam niining handheld device para sa on-site testing aron mapabilis ang pagidentify sa counter abnormalities, ensuring the protective function of line arresters during thunderstorms.
2. ​Arrester Installation and Maintenance Acceptance​
• ​New Equipment Installation Acceptance:​​ Para sa bag-o nga nabili nga arresters, bago o human sa installation, ang power companies nanginahanglan og gamiton kini nga device aron makaverify ang operational reliability sa discharge counter. Kon ang counter dili makarespond ng eksakto sa simulated discharge signals, ang equipment mahimo nga molihok sa wagtang, naaasikaso ang faulty arresters nga dili ma-commissioned ug namalihan ang safety risks sa source.
• ​Post-Maintenance Function Verification:​​ Human sa arrester undergo overhaul maintenance o component replacement (e.g., counter module replacement), kini nga device dapat gamiton sa discharge operation test. Makakakumpirma kung ang counter accurately records discharge events, ensuring the restored protective function of the maintained arrester, avoiding counter failure due to inadequate maintenance.
3. ​Laboratory Testing and Third-Party Services​
• ​Arrester Production Quality Inspection:​​ Ang mga arrester manufacturers makagamit kini nga device sa laboratory para sa batch testing sa discharge counters sa finished products, ensuring the counting accuracy of each unit meets industry standards (e.g., reliable counting when discharge current exceeds 100A), thereby improving product qualification rates.
• ​Third-Party Testing Services:​​ When providing arrester performance testing services to clients, third-party inspection agencies can leverage the portability and wide-scenario adaptability of this device to perform counter operation verification either on the client's site or in the laboratory, providing clients with accurate test reports and assisting them in compliant maintenance.

​II. Solution Implementation Process​

1. ​Preparation Phase: Define Requirements and Debug Equipment​
• ​Requirement Confirmation:​​ Based on the application scenario (e.g., substation inspection, new equipment acceptance), define the testing standards. For example, substation inspection may require confirming the counter operates normally under an adjustable output voltage of 200~1600V, with a discharge current response threshold not less than 100A.
• ​Equipment Debugging:​​
1. Check power supply status: The device is powered by a rechargeable lithium battery; ensure sufficient charge (recommended to charge fully beforehand to meet all-day field testing needs).
2. Connect test leads: According to the user manual, connect one end of the test lead to the device's output terminal and the other end to the signal interface of the arrester discharge counter, ensuring secure connections and no short circuits.
3. Set test parameters: Adjust the output voltage (200~1600V adjustable) based on the arrester type (e.g., metal oxide, silicon carbide valve-type). Confirm the device's rated frequency (50Hz) matches the grid frequency at the site to avoid frequency mismatch affecting results.
2. ​Testing Phase: Simulate Discharge and Verify Operation​
• ​Simulated Discharge Test:​​ Activate the device's discharge test function. The device outputs a simulated arrester discharge signal (discharge current > 100A). Observe the operation of the arrester discharge counter:

• If the counter increments normally (e.g., records 1 discharge), the counter is deemed reliable.
• If the counter shows no response or incorrect counting, mark the arrester as faulty, suspend its operation, and proceed with further investigation.

• ​Data Recording and Repeated Verification:​​
1. Record test data: Include test time, arrester ID, device output voltage, discharge current, counter operation result (Normal / Abnormal), etc., for future traceability.
2. Repeat test: For counters showing abnormal results initially, adjust the output voltage (e.g., from 500V to 800V) and repeat the test 2-3 times to rule out misjudgment due to operational error, ensuring accuracy.
1. ​Post-Testing Phase: Abnormal Handling and Equipment Maintenance​
• ​Abnormal Handling:​​

• If the abnormality is due to poor contact, re-tighten the signal interface connections and retest.
• If the counter's internal module is faulty (e.g., circuit damage, mechanical jamming), replace the counter module. After replacement, use the device to re-verify until the counter operates normally.
• For arresters consistently showing abnormalities after multiple tests, take them out of service promptly and schedule repair to prevent loss of protection during thunderstorms.

• ​Equipment Maintenance:​​
1. After testing, turn off the device power, and neatly coil the test leads to prevent damage from tangling.
2. Clean the device exterior: Wipe the surface with a dry, soft cloth, especially the output ports, to prevent dust accumulation causing poor contact.
3. Battery maintenance: If the device is unused for extended periods, charge the lithium battery periodically (e.g., monthly) to prevent damage from deep discharge and extend battery life.
