High-Voltage Circuit Resistance Tester

Basic Functions:

Currently, conventional methods are widely used in the power system.QJ44The model dual-armed DC bridge measures contact resistance, while the test current for such bridges is onlymAIt is difficult to detect the defect of reduced cross-sectional area in the loop conductors. When measuring the contact resistance of the conductive circuit in high-voltage switches, the measured values are several times larger due to the influence of the oil film and oxidation layer between the contacts, failing to accurately reflect the actual contact resistance value.

As a result, the new Ministry of Power standardsDL/T845.4—2004"General Technical Conditions for Resistance Measurement Devices: Loop Resistance Meters" and the new version of the Verification RegulationJJG1052-2009"Regulations for the Calibration of Circuit Resistance Meters and Direct Resistance Meters stipulate that the measuring current for contact resistances of switches (isolated), circuit breakers, etc. shall not be less than direct current."100APlease provide the Chinese content you would like translated.60SRegulations are in place to ensure accurate test results.

ED0303B-100The ergonomic design of the contact resistance tester's operating panel aligns with user habits. It utilizes high-frequency switching power supplies and digital circuit technology, suitable for measuring the circuit resistance of switch control devices.

Test current is conducted using the direct current recommended by the national standard.100APlease provide the Chinese content that needs to be translated into American English.100AThe loop resistance was directly measured, with the test results displayed on a large LCD screen.LCDDemonstrates, and features data storage, output printing, time setting functions, as well as50AGear options available for user selection; customizable test time, with a long setting time.599S,Significantly greater than the standard requirements.60SPlease provide the Chinese content to be translated..No Chinese content provided.0.01μΩ resolution and highly stable contact resistance tester, outperforming imported high current micro-ohmmeters.

Meets the requirements for on-site high-voltage switch maintenance for power and electricity supply departments, as well as circuit resistance testing in high-voltage switch factories.

Technical Features:

High Current:

Utilizing the latest switch mode power supply technology, it can continuously output high currents for extended periods, overcoming the drawbacks of pulsed power supplies' instantaneous current spikes. This effectively punctures the oxidation film on switch contacts, yielding excellent test results.

High Stability:

Under severe interference conditions, the data behind the liquid crystal display can remain stable.±1Within a certain range, the readings are stable and reproducible.

High Precision:

Intelligentization:

Import High-PerformanceCPUDuring measurements, the system automatically switches ranges based on signal size to ensure testing accuracy. The over-temperature protection circuit automatically stops outputting current when the instrument exceeds the set temperature, ensuring safe operation of the equipment.

High Quality:

All critical components are imported, and the influence of environmental temperature on measurement results is effectively eliminated through a cleverly designed temperature compensation circuit. The use of military-grade connectors enhances vibration resistance.

Powerful:
