Technical Analysis of ZXJS-I Handheld Arrester Counter Tester Abstract

Lightweight handheld testing instruments have become an indispensable on-site testing tool for modern power operation and maintenance, solving the pain points of bulky equipment, complicated operation and low testing efficiency of traditional arrester counter detection devices. This paper focuses on the ZXJS-I handheld arrester counter tester independently developed for power industry demand, elaborates its design advantages, core functional features and complete technical parameters, and analyzes its practical application value in lightning arrester inspection work for frontline power technical staff.

1. Product Development Background & Design Concept

With the continuous expansion of power grid scale, the regular calibration and functional verification of surge arrester counters have become a key routine work to guarantee lightning protection safety of transmission and transformation equipment. Conventional arrester counter testing equipment has prominent defects: large overall volume, heavy weight, complex wiring and slow measurement procedures, which greatly increase the labor burden of field test personnel, and cannot meet the requirements of rapid batch detection in outdoor substation and line inspection scenarios.

To address the actual testing demands of power grid users, the R&D technical team completes targeted optimization and independent development of the ZXJS-I handheld arrester counter tester. Different from the cumbersome structural design of traditional test equipment, this tester adopts integrated miniaturized layout, with streamlined appearance and humanized portable design. It completely replaces outdated bulky test equipment and backward testing processes, and has gained wide recognition and extensive application among power operation and maintenance professionals.

2. Core Performance Features of ZXJS-I Tester

The ZXJS-I handheld arrester counter tester owns two core competitive advantages for field power testing:

Ultra-compact & lightweight structure The whole machine adopts miniaturized component integration design, which realizes small overall dimension and low self-weight. Field technicians can carry and operate the device with one hand without auxiliary carrying tools, effectively adapting to narrow equipment intervals, high-altitude line operation and other complex working environments.

Safe, rapid and high-precision measurement workflow Safety is the primary indicator of power live-test equipment. This tester optimizes internal voltage conversion and isolation circuit, which eliminates hidden dangers of electric shock during the testing process. The built-in fast response testing circuit shortens single detection time significantly, and stable signal acquisition module ensures consistent, accurate and repeatable measurement data, avoiding test deviation caused by equipment aging or unstable output of traditional instruments.

3. Detailed Technical Specifications

All technical indicators of ZXJS-I arrester counter tester are calibrated in accordance with power lightning protection testing standards, and the specific parameters are listed as follows:

Overall geometric dimension: φ36mm × 375mm; Test probe head dimension: φ50mm × 100mm

Net weight of complete machine: 780 grams

Power supply mode: DC 6V, powered by No.1 dry battery, convenient for on-site battery replacement without relying on fixed AC power supply

Adjustable output voltage range: 800V ~ 1600V The wide adjustable output voltage range covers the excitation voltage demand of most mainstream arrester counters in power grids, realizing compatible detection for various types of lightning protection counting devices. The DC 6V battery power supply design thoroughly solves the trouble of carrying power cords and inverters for outdoor field tests, greatly improving the mobility of inspection work.

4. Application Value in Power Lightning Protection Testing

Improve field operation efficiency The portable lightweight design removes the restriction of transportation space for test tools; one-step rapid measurement cuts down single counter detection time, which remarkably promotes the completion efficiency of regular arrester batch calibration tasks in substations.

Reduce operation safety risks Optimized internal isolation circuit and stable voltage output avoid overvoltage surge in the test loop, lowering the risk of equipment damage and accidental electric shock for testing staff.

Wide scene adaptability It is applicable to routine inspection of arresters in overhead transmission lines, distribution boxes, indoor and outdoor substations, and can work stably under temporary outdoor operation conditions without fixed power supply.

5. Conclusion

As a new-generation portable special testing equipment for arrester counters, the ZXJS-I handheld arrester counter tester breaks through the performance bottlenecks of traditional detection instruments from structural design, circuit optimization and power supply mode. Its compact lightweight layout, safe fast testing performance and standard matched technical parameters perfectly fit the lightweight, high-efficiency development trend of modern power grid operation and maintenance. For power technical practitioners, this tester can serve as a standard matching tool for daily lightning protection equipment inspection, effectively supporting the stable operation of power grid lightning protection systems.
