(A) an overview of 

 The HS100 series Zhuhai, Han Sheng Electronics Technology Co., Ltd. based on the current system, medium voltage switchgear technology development, design and development of a new type of modular, intelligent operation measurement display device. 
 This series of products set loop simulation instructions, live instruction and lockout, temperature and humidity digital real-time display, automatic heating and dehumidification control, automatic ventilation cooling control, circuit breaker and closing status indication, energy storage, grounding switch instructions Handcart position instructions, the human body sensors voice prompts, and intelligent anti-mistaken voice prompts, the main circuit power parameter measurements show that temperature and RS485 communication interface function of the high-voltage electrical contacts in one, may need to matching. 
 This series of products to the instructions of the integration will simplify the structural design of switchgear panel layout accessory equipment in the switch cabinet, beautifying the switchgear panel layout, and improve the switching state function and safety performance. 
 This series of products can be used within 3 ~ 40KV indoor switchgear, apply to the counters in the home, the handcart cabinet, fixed cabinet, ring network cabinet and other switchgear to comply with IEC255-22 standard.
