Petrochemical Electrical Fire Protection Solution

Electrical Fire Causes in Petrochemical Plants

Petrochemical plants run continuously with densely arranged electrical equipment, and with flammable/explosive media nearby, the consequences of electrical fire are more severe than in other industries:

• Concentrated equipment in process areas: refining unit distribution cabinets and MCC cabinets sit next to process areas; electrical sparks may ignite surrounding combustible media
• High-temperature, corrosive environment: high ambient temperature in process areas and sulfur-containing gas accelerate insulation aging; short-circuit risk rises with service life
• Dense cable trenches and trays: tens of thousands of meters of cable laid across the plant; a single fault arc may spread widely along trays
• High cost of safe shutdown: unplanned process shutdown means long restart cycles and large direct losses; fire protection must accommodate continuous operation

The core challenge of petrochemical electrical fire protection is: covering blind-spot risk points during equipment aging while ensuring continuous, uninterrupted process operation.

Solution Overview

This solution applies AFCP composite agile fire-control patches over key electrical nodes such as distribution cabinets, MCC cabinets, and cable joints; EAPD devices monitor temperature and arc anomalies in important distribution circuits; and the ICOP platform manages plant-wide electrical safety — forming a petrochemical electrical active protection system of "patch node coverage — device circuit monitoring — platform plant-wide management."

Overall approach: AFCP patches are mounted directly on busbar joints inside process-area distribution cabinets, on MCC drawer unit outgoing terminals, and inside high-voltage motor junction boxes — the most critical yet vulnerable electrical connection points in petrochemical production. The patch introduces no electronic components, so it does not affect explosion-proof rating or safety certification. EAPD devices are deployed in important distribution rooms and cabinet rooms, continuously monitoring temperature and arc parameters. The ICOP platform receives plant-wide data so the duty dispatcher can grasp the safety posture of all distribution nodes on one screen.

Typical Protection Points

Core Product Configuration

AFCP Composite Agile Fire-Control Patch

A single patch provides on-site protection, addressing electrical fire risks at the source:

• Passive and purely physical: introduces no electronic components, suitable for petrochemical explosion-proof zone safety requirements
• Point-to-point coverage: attached to specific heat points such as distribution cabinet busbars and MCC outgoing terminals for targeted, gap-free protection
• Corrosion and weather resistant: patch structure tolerates the harsh conditions of process areas — high temperature, sulfur corrosion, and vibration
• Installation without shutdown: patches can be installed while equipment runs normally, with no production stoppage

EAPD Electrical Active Protection Device

Very early warning that actively suppresses before a fire develops; it focuses on monitoring temperature and arc anomalies in important distribution rooms and cabinet rooms, reporting anomalies to the ICOP platform to gain a response window for maintenance staff.

ICOP Intelligent Integrated Operation Platform

Connects to EAPD data from distribution rooms and cabinet rooms plant-wide, displaying each process area's electrical safety status in a unified view; graded alarms are pushed to dispatch and maintenance staff, with historical data review and equipment-aging trend analysis support.

Benefits After Deployment

Extended Application Scenarios

This solution also applies to coal chemical, fertilizer, synthetic fiber, and fine chemical process industries. The core logic is consistent — patch coverage on process-area distribution nodes, EAPD monitoring at key circuits, and ICOP plant-wide management. It can be combined with Liquid Shield coating to address dead corners in cable trays and behind distribution cabinets.

Standards and Compliance

This solution's technical approach references petrochemical electrical fire protection design codes and the AFCP series enterprise standards, using clean non-conductive extinguishing agent suitable for active protection of petrochemical distribution and motor control circuits. Combined with the EAPD device and ICOP platform, it follows the "monitoring — warning — local protection" active electrical protection technical direction.
