产品描述

Commodity name: Switchgear Equipment Live Detection Solution

Product Overview
Switchgear cabinets have a relatively high accident rate due to varying degrees of issues in design, manufacturing, installation, and operation/maintenance. Additionally, factors such as humidity, contamination, weak insulation, and intrusions by small animals frequently lead to accidents. The live detection technology for switchgear cabinets leverages techniques like transient ground voltage, ultrasonic waves, and ultra-high-frequency methods, enabling inspections while equipment remains operational—thus avoiding the inconvenience and safety risks associated with conventional power-off testing. By conducting live tests, potential insulation problems can be identified promptly, allowing for timely maintenance measures to prevent equipment damage and power outages, ultimately enhancing the reliability and safety of power supply.

Detection Cycle

Serial Number	Project	Cycle
1	Transient Voltage Detection	1) Six months to 1 year; 2) After commissioning; 3) When necessary
2	Ultrasonic Testing	1) Six months to 1 year; 2) After commissioning; 3) When necessary
3	Ultra-High-Frequency Detection	1) Six months to 1 year; 2) After commissioning; 3) When necessary

Detection Cases


Arcing discharge on the surface of the circuit breaker arc-extinguishing bushing	Surface discharge of cables inside the cabinet	Surface Discharge on Supporting Insulators	Suspension discharge

Switchgear live detection technology, by comprehensively applying various detection methods, can effectively identify and prevent multiple defects during switchgear operation, such as poor contact, insulation aging, insufficient electrical clearance, and equipment moisture. This, in turn, enhances the operational efficiency and safety of the power grid.
