1. Product Overview

The Lanso Instruments TIMB-5R Intelligent Maintenance-Free Breather is a core auxiliary device installed on the conservator tanks of oil-immersed transformers. It is designed to address moisture ingress and insulating oil degradation caused by transformer breathing processes.

Replacing conventional silica gel breathers, the TIMB-5R integrates automatic moisture absorption, intelligent regeneration, and remote monitoring functions into one system. It eliminates the need for frequent manual desiccant replacement, reduces operational risks and maintenance costs, and ensures long-term stability of insulating oil performance.

Equipped with an intelligent monitoring and heating regeneration system, the breather automatically adjusts its operation according to the transformer breathing status, effectively preventing moisture backflow into the transformer. It is suitable for various types of oil-immersed transformers and on-load tap changer (OLTC) conservator tanks, making it an ideal accessory for the operation and maintenance upgrade of smart substations.

2. Key Functions

1. Automatic Moisture Absorption and Regeneration

Efficiently absorbs moisture and impurities from the incoming air. Once the desiccant reaches saturation, the system automatically activates heating regeneration to restore drying performance for repeated use, eliminating manual desiccant replacement and achieving true maintenance-free operation.

2. Breathing-Synchronized Moisture Protection

Monitors three transformer operating states in real time: breathing, air intake, and standby conditions. The system intelligently determines the optimal regeneration timing to prevent humid air from entering the transformer and contaminating the insulating oil.

3. Full-Parameter Visualization

The LCD display operates reliably even in low-temperature environments down to -40°C, providing real-time visualization of:

• Silica gel temperature and humidity
• Breathing pipeline temperature and humidity
• Operating status information

The clear and intuitive display enables convenient equipment monitoring.

4. Multiple Communication and Remote Monitoring

Supports three communication interfaces:

• 4–20 mA
• RS485
• Local USB

Key operating parameters and fault alarms can be transmitted remotely, enabling unattended monitoring and intelligent operation.

5. Low-Temperature Safety Protection

Automatically ensures drainage and ventilation channel availability below 0°C, preventing ice blockage and guaranteeing stable operation under extreme environmental conditions.

3. Product Advantages

Maintenance-Free Design, Reduced Operating Costs

The desiccant regeneration cycle eliminates manual replacement requirements and reduces maintenance workload and outage-related costs, decreasing routine maintenance efforts by more than 80%.

Intelligent, Safe, and Reliable Operation

Breathing-synchronized control, anti-freezing protection, and built-in protective wiring design effectively prevent risks such as incorrect operation, moisture backflow, and ventilation blockage, ensuring safer transformer operation.

Excellent Environmental Adaptability

The control unit features:

• IP67 protection rating
• Wide operating temperature range from -40°C to +70°C
• Strong electromagnetic compatibility compliant with the GB/T 17626 series standards

It is suitable for outdoor installations and harsh operating environments.

Digital Upgrade Capability

Supports both local parameter configuration and remote monitoring, seamlessly integrating with automated operation and maintenance systems for smart grids. The TIMB-5R is suitable for both newly built substations and retrofit projects for existing facilities.
