In the safe operation of power systems, insulated boots serve as essential safety equipment for power workers, and the reliability of their insulation performance directly impacts the safety of these workers. As a key piece of equipment for verifying the power frequency withstand voltage performance of insulated boots, the fully automatic water-injection insulated boot testing system is becoming standard equipment for power operation and maintenance units and safety tool testing centers. Leveraging years of expertise in high-voltage testing technology, Wuhan Goldhome Hipot Electric Co., Ltd. has developed a fully automatic insulated boot withstand voltage testing system. With core advantages such as intelligent control, precise measurement, and efficient testing, this system provides a solid foundation for safe operations in the global power industry.
Preventive Testing by Power Operation and Maintenance Units
The primary application scenario for the Goldhome fully automatic water-injection insulated boot testing system is preventive testing conducted by power companies, substations, power supply bureaus, and other operation and maintenance units. According to relevant standards such as the "DL/T 1476-2015 Code for Preventive Testing of Electrical Safety Tools" and "GB 21148-2020 Foot Protection-Safety Footwear," the dielectric withstand test cycle for insulated boots is six months. During testing, breakdown is not permitted, and the leakage current must not exceed the specified limit.
Goldhome's testing system can simultaneously perform power-frequency withstand voltage tests on eight pairs of insulated boots, with an output voltage range of AC 0–50 kV and a leakage current measurement range of 0–30.0 mA, featuring a measurement error of ≤1% ±3 digits. The equipment employs advanced wireless leakage current acquisition technology. After on-site sampling of the 8-channel leakage currents, the data is wirelessly transmitted to the control host. If any channel experiences breakdown or exceeds the set leakage current value, the corresponding test sample is immediately removed from the test, allowing other samples to continue testing without interruption. This design enables maintenance and operation units to complete periodic inspections of large batches of insulated boots in a short time, ensuring that the safety equipment of frontline workers remains in a qualified state at all times.
Batch Testing at Safety Equipment Testing Centers
At professional testing institutions such as third-party testing agencies, power research institutes, and safety equipment quality inspection centers, the Goldhome fully automatic water-injection insulated boot testing system plays a central role in batch testing and data management. The system is equipped with host computer software that controls the entire voltage ramp-up and ramp-down process, displays measurement data in real time, and automatically generates and prints standardized test reports.
Testing personnel need only select the insulation boot class on the touchscreen, and the device will automatically complete the entire process-including water filling, voltage ramp-up, timing, voltage ramp-down, and power disconnection-in accordance with regulatory requirements. A single screen simultaneously displays parameters such as test voltage, low-voltage output current, 8-channel high-voltage leakage current, and elapsed time, providing a wealth of information in an intuitive and clear manner. The data storage function supports historical data queries and traceability, meeting the certification and accreditation requirements of testing institutions.
Factory Acceptance Testing for Insulated Boot Manufacturers
For manufacturers of insulated boots, the Goldhome Fully Automatic Water-Filling Insulated Boot Test System is a critical piece of equipment for product quality control and factory acceptance testing. The system uses high-precision stepper motors to control the voltage regulator's ramp-up process. Once the test begins, it automatically closes the circuit and increases the voltage at the rate specified by national standards. Upon reaching the preset voltage, it automatically starts the timer, reduces the voltage, and cuts off the power. This standardized testing process ensures that every batch of products is inspected under identical conditions, eliminating errors caused by human operational variations.
To meet the needs of type testing during the R&D phase, the Goldhome testing system can be configured to match the voltage transformation ratio of the customer's existing transformer, enabling compatibility with transformers of various specifications. The leakage current measurement range can be customized to extend from 0 to 50 mA, accommodating the testing requirements of products with special specifications.
Technological Innovation and Intelligent Operation
The core value of the Goldhome fully automatic water-injection insulated boot testing system lies in its intelligent operational design. The insulated boot test employs a dry testing method using small steel balls; by placing small steel balls inside the insulated boot instead of the traditional water-filling method, it completely resolves the issue of difficulty in drying the boot after testing. A sponge is placed at the bottom of the water tank; the insulated boot is placed on the sponge, and water is automatically injected into the tank until the sponge is fully saturated.
The device employs advanced PLC control, enabling multiple functions such as one-touch water filling, specimen position detection, water tank level monitoring, and automatic reset. Both the water filling unit and the control unit feature large touchscreen displays with Chinese character interfaces. Real-time status prompts throughout the water filling process ensure testing accuracy and safety, making the equipment easier to use and maintain.
