As indoor switchgear evolves rapidly toward integration and intelligence, traditional decentralized indication and control methods can no longer meet the critical demand for safety, reliability, and efficient operations in modern power systems. Building on years of expertise in power equipment condition monitoring and intelligent sensing technologies, we are proud to launch our new generation Multi-Function Intelligent Switch Analog Comprehensive Dynamic Indicator. This device integrates multiple capabilities, including primary circuit analog indication, trolley position status, disconnecting switch and earthing switch states, breaker open/close status, spring charging status, high-voltage live display with interlock, smart temperature and humidity control, online electrical contact temperature monitoring, partial discharge detection, arc flash protection, insulation monitoring, and video surveillance. It fully empowers intelligent operation, maintenance, and safety protection for medium-voltage switchgear.

Product Overview

Designed for indoor switchgear operating at 0.1～40.5kV kV, this device features a modular, highly integrated architecture that consolidates functions previously requiring multiple discrete meters and indicators into a single unit. It significantly simplifies panel layouts, enhances cabinet aesthetics, and improves switch status indication and safety performance. Widely adopted across power, chemical, railway, mining, metallurgy, and cement industries, the series has earned strong user recognition for its practicality and reliability.

Core Technical Features

High-Performance Hardware Platform

The device features a high-performance industrial-grade microprocessor paired with an industrial-grade 32-bit communication processor, delivering powerful data processing and storage capabilities with fast operation and high reliability. It also incorporates low-power design, supporting multiple sleep and wake modes to minimize overall power consumption and ensure reliable long-term operation under continuous power conditions.

System Stability Design

Built-in WDT hardware watchdog ensures stable operation in complex electromagnetic environments, eliminating crashes or abnormal reboots. Supports serial software upgrades and remote maintenance to reduce on-site operational complexity.

All-in-One Integrated Solution

In addition to standard features such as switch status indication, primary circuit simulation, handcart/isolator/grounding switch position monitoring, and spring charging status, this device integrates the following advanced capabilities:

High-voltage live indicator and live-lock output to prevent accidental entry into energized compartments.
Auto heat and dehumidify with real-time digital temperature and humidity display. Includes heater fault monitoring, overheating alarm, and automatic heating shutdown.
Smart voice anti-error prompts and infrared human body sensing enhance operational safety
Online temperature monitoring for internal electrical contacts with flexible sensor options (e.g., SAW, infrared, wireless). Provides real-time, accurate, and fast-response measurements.
Real-time online temperature monitoring with accurate data reflecting contact heating trends.
Integrates power measurement, partial discharge monitoring, arc flash detection, and insulation analysis to upgrade from a single-indicator device to a comprehensive switchgear condition monitoring terminal.
Optional video surveillance for clear visibility of in-cabinet equipment and operating environment
Touchscreen HMI with clear display, high resolution, and smooth, intuitive operation

Data Storage and Communication

Leverages advanced storage technology to retain settings after power loss, ensuring persistent configuration. Equipped with an RS485 communication interface for integration into comprehensive automation systems or operations platforms, enabling remote monitoring and data aggregation.

Application Value

This device is designed for medium-voltage switchgear operating at 0 kV to 40.5kV kV. It is particularly suited for new substations, industrial power distribution rooms, and retrofit projects for aging switchgear that demand high integration, reliability, and intelligence. By providing a unified view of critical parameters—including switch status, temperature and humidity control, contact temperature, partial discharge, arc detection, and insulation performance—it enables maintenance teams to quickly assess equipment health, detect potential faults early, minimize unplanned outages, extend asset life, and transition from scheduled maintenance to condition-based monitoring.
