EL switchgear intelligent control device

Best Industries (Hong Kong) LimitedWe are a large enterprise specializing in the production of intelligent control devices for switchgear. Based on years of production experience and strong technical strength, we use advanced microcomputer (MCU) measurement and control, dual MCU backup detection, and digital signal processing technology to develop and produce intelligent control devices for switchgear. It has powerful functions, including dynamic simulation display of the primary circuit of the switchgear, pre opening and pre closing flashing indication, cumulative opening and closing times of the circuit breaker, voice error prevention prompt, temperature and humidity display and control inside the cabinet, online temperature measurement of the dynamic and static contacts/cable overlap surface, high-voltage live display and locking, electrical testing/phase verification (optional), voice prompt for busbar live induction, operation switch, lighting operation, opening and closing indication, energy storage indication, RS-485 communication interface and fault detection, etc; In addition, it can also be networked with other electrical equipment in the power system, making it an ideal tool with powerful functions, easy operation, and adaptability to modern power management.

intelligentizationUsing two single-chip microcontrollers for control, compared with conventional switchgear status display devices, it not only has a more user-friendly human-machine interface and intelligent functions, but also adds automatic detection and troubleshooting functions for device module faults. In addition to providing voice prompts for misoperation of the switchgear, it can also determine whether the switchgear trolley is between the test position and the working position or outside the cabinet and give instructions; At the same time, this device also has fault detection capabilities for the intact status of temperature and humidity sensors, heater faults (including heater disconnection and short circuit), the intact status of the main control CPU, and the intact status of the high-voltage live display module. Once there is a fault, an alarm signal is issued and a relay switch signal is output. For heater faults, the faulty module can be automatically disconnected to prevent the fault from expanding and causing accidents.

Strong anti-interference abilityAdopting unique anti-interference technology, fully considering its EMC performance during the product design phase.

high reliabilityUsing industrial grade electronic components (with military grade CPUs) and independent module fault detection CPUs (dual CPUs), the system automatically detects and identifies faulty modules, allowing for online maintenance and module replacement without the need for power outages or device disassembly, truly achieving online safe maintenance. This device not only has high reliability, but also has the characteristics of long service life and strong anti-interference ability. The light-emitting module adopts imported light-emitting chips, with outdoor high brightness level and a lifespan of 170000 hours.

custom-madeWe can tailor feature rich combination products according to different customer needs.

exquisite and elegantThe appearance design is novel and unique, with exquisite workmanship, simplifying and beautifying the switchgear panel.
