Industrial Substation Product Introduction

1. Product Brief Introduction

The industrial substation is a complete set of power distribution equipment designed for industrial production scenarios, integrating transformers, high and low voltage switchgear, protection and monitoring devices, reactive power compensation components, etc. It realizes voltage reduction, distribution, protection and energy-saving control of electric energy, and has the characteristics of compactness, intelligence and high reliability. It adapts to the load characteristics and usage environment of industrial plants, and can be directly installed in industrial production workshops, factory area power distribution rooms, outdoor industrial operation sites, etc. It replaces traditional civil-built substations, greatly shortens the construction period and saves floor space.

2. Scope of Application

• Manufacturing industry: power distribution in industrial production plants and workshops such as machinery processing, automobile manufacturing, electronic and electrical appliances, metallurgy, chemical industry, textile, building materials, etc.
• Industrial parks: centralized power distribution in industrial parks, economic development zones, industrial zones and enterprise-specific power distribution.
• Heavy industry: power supply for power distribution in mining areas, ports, docks, engineering machinery operation areas.
• Other industrial scenarios: power distribution needs of industrial warehousing centers, cold chain industrial parks, and industrial supporting facilities.
• Voltage level configuration: industrial low-voltage power distribution systems with 10kV/35kV incoming lines and 0.4kV outgoing lines, covering industrial load power supply from small and medium power to medium and large power.

3. Model Definition (Taking 10kV Prefabricated Industrial Substation as an Example, Industry Universal Compilation Rules)

The model number of industrial substation is usually compiled by prefabricated substation universal code + voltage level + transformer capacity + structure/characteristic code. The core model such as YBM-12/0.4-630, the definition of each part is as follows:

• YBM: Prefabricated substation (general code for prefabricated substation), Y - Prefabricated, B - Substation, M - Sealed type (commonly used in industry, suitable for multi-dust/humid environment); if it is outdoor explosion-proof type, it is marked as YBM-F, and indoor compact type is marked as YBM-N
• 12/0.4: Rated voltage, 12kV (10kV system universal) on high voltage side, 0.4kV on low voltage side
• 630: Main transformer rated capacity, unit kVA, which can be configured as 200/315/400/800/1000kVA according to industrial load requirements
• Extended code: such as G - Outdoor type, Z - Intelligent type, K - Mining industry type, customized for special industrial scenarios
