Safety Operating Procedures for Container Type Substations

A Container Type Substation is a compact distribution device that integrates high-voltage switchgear, distribution transformers, and low-voltage distribution devices into a movable steel-structured container according to a certain wiring scheme.

 

I. Characteristics of Container Type Substations

The core characteristics of Container Type Substations are high integration, small footprint, rapid installation, easy transportation and relocation, and good protective performance. They are suitable for various temporary or permanent power supply scenarios.

III. Advantages of Container Type Substations

The advantages of Container Type Substations lie in their high integration and rapid deployment. They pre-fabricate high-voltage equipment, transformers, low-voltage devices, and other components within a sturdy container, achieving a modular combination. Container Type Substations have a short construction period, occupy a small area, have low investment costs, can be moved and reused as a whole, and have strong environmental adaptability. They can also be operated unattended through intelligent systems, making them particularly suitable for urban distribution networks, temporary power supply, and rapid capacity expansion scenarios.

 

 

IV. Safety Operating Procedures for Container Type Substations

1. Personnel and Preparation

Qualification Requirements: Operators must have a valid certificate and be familiar with the equipment structure and operating procedures.

Personal Protection: Before operation, operators must correctly wear qualified protective equipment such as insulating gloves, insulating shoes, and safety helmets.

Pre-Operation Inspection of Container Type Substations:

Check the appearance of the Container Type Substations and whether the door locks are intact, and ensure the surrounding environment is tidy.

Check whether the grounding system, instrument indications, and safety equipment are normal and qualified.

Clarify the current status of the Container Type Substations and verify the operating tasks.

 

 

2. Power Delivery (Commissioning) Operation of Container Type Substations

Confirm Safety: Confirm that maintenance work on the Container Type Substation has been completed, safety measures have been removed, no one is inside the container, and the container doors are closed.

Check Grounding: Check and confirm that all grounding switches of the Container Type Substations are in the open position.

High-Voltage Side Power Delivery: After obtaining permission, close the high-voltage disconnect switch (if any), load switch, or circuit breaker in sequence, and observe that the high-voltage live indicators and instrument readings are normal.

Low-Voltage Side Power Delivery: After confirming that the transformer of the Container Type Substation is operating normally, sequentially close the low-voltage main switch and each outgoing branch switch, and observe that the low-voltage instrument readings are normal.

 

3. Power-off (maintenance) operation of Container Type Substations

Power-off on the low-voltage side: Disconnect the outgoing branch switches on the low-voltage side of the Container Type Substations in sequence, then disconnect the low-voltage main switch.

Power-off on the high-voltage side: Disconnect the load switch or circuit breaker on the high-voltage side of the Container Type Substations, then disconnect the high-voltage isolating switch (if available).

Voltage testing and grounding: Use a qualified voltage tester to test each phase on all sides that may have power. After confirming there is no voltage, immediately install the grounding wire or close the grounding switch.

Hang signage: Hang a sign on the operating handle stating "Do not close the switch, people are working!"

 

 

4. Operation Inspection and Maintenance of Container Type Substations

Daily Inspection: Check the operating sounds, temperature, instrument readings, and any unusual odors of the Container Type Substation every day.

Regular Inspection: Regularly check whether the electrical connection points of the Container Type Substations are overheated, the transformer oil level/oil temperature (for oil transformers), and the sealing and ventilation of the enclosure.

Abnormal Handling: Immediately record and report any abnormalities found; under no circumstances should the equipment operate with faults.

 

 

V. Introduction to Relevant Knowledge of Container Type Substations

1. What content should be checked during the daily inspection of a Container Type Substation?

Check whether the appearance is normal, whether the meter readings are normal, whether the equipment operating sounds and temperatures are abnormal, whether there is any odor inside the container, and whether the surrounding environment is clean, etc.

2. In what locations are Container Type Substations suitable?

Container Type Substations are widely used in urban power grids, residential communities, industrial parks, temporary construction power, wind and solar new energy power stations, mines, airports, docks, and other places that require flexible and rapid power supply.

 

Container Type Substations have many advantages and a wide range of applications, and users should choose the appropriate model of Container Type Substation according to specific work needs.
