What is ITB?
A digitally enhanced substation device that integrates real-time monitoring, active desiccant regeneration, and predictive analytics into traditional transformer breathing systems.
It employs dual-tank redundancy to prevent clogging and AI-driven moisture control to achieve maintenance-free operation, while accumulating conservator respiration data to preempt critical failures (e.g., false oil level alarms). This innovation significantly reduces OPEX and advances grid intelligence.
Our Advantage:
1.Dual-tank active-standby configuration prevents pipeline blockage.
2.Active silica gel regeneration technology dynamically adjusts desiccant reactivation cycles based on ambient conditions, achieving near-zero maintenance.
3.Accumulates conservator breathing data with proprietary algorithms to preemptively warn of risks such as false oil level indication.
4.This high-efficiency, eco-friendly solution elevates substation intelligence, reduces OPEX by 30%+, and delivers significant economic/social benefits.
Comparison of Existing Breather Technologies
Traditional Breather
1.Traditional breathers require regular on-site inspections and maintenance during long term use. When the oil in the oil-seal cup absorbs too many impurities and is severely contaminated, it needs to be replaced. When the discolored silica gel changes color beyond a certain proportion, it also needs to be replaced.
2.Silica gel is very likely to come into contact with air during various recycling and drying processes, resulting in a decrease in its service life, and may even directly crack, decompose into crystals and dust. Normal discolored silica gel has stable chemical properties and is non-toxic, but the discolored silica gel that has decomposed into crystals and powder contains toxic cobalt chloride. Long term inhalation of dust containing cobalt chloride irritates the respiratory tract and is likely to cause various diseases, endangering human health.
3.Every time the silica gel is replaced, various measures need to be taken. When the breather is disassembled and assembled, the oil conservator directly contacts the air, which may cause false operation of the gas relay. At the same time, environmental pollution needs to be prevented, etc.
4.Due to the lack of remote monitoring, the cost of long term on-site inspection and maintenance of transformer breathers will increase exponentially.
Maintenance-free Breather
1.Imported maintenance-free breathers are mainly products from Germany, Italy, the UK and other countries, and there are many domestic imitations of German products.
2.Currently, maintenance-free breathers all use heating methods for silica gel regeneration, expelling moisture by using the method of exhaled air flow, or forming condensed water by using the condensation method of a glass cover, and then discharging it from the breather.
3.Since the breathing time of the transformer is difficult to predict, when the exhaled air flow is small and discontinuous, the regeneration effect of the silica gel will be poor, and there is a risk of inhaling moisture into the transformer oil conservator.
4.The regeneration judgment conditions are simple, the state of the silica gel is not well understood, and there is a risk of blockage in a single three-way valve.
5.It is a non-intelligent technology and is difficult to be managed as a transformer intelligent component.
Intelligent Monitoring Maintenance-free Breather Technology
Technical Features of the Intelligent Monitoring Maintenance-free Breather:
1.A brand-new design that makes up for the current technical deficiencies and realizes the visualization and digitization of the transformer's breathing state.
2.Active regeneration technology enables silica gel regeneration even when the transformer is not breathing.
3.The design of mutually repelling electromagnetic valves and controllers fundamentally avoids pipeline blockage failures.
4A unique silica gel heating and sensing assembly ensures that the heating airflow can evenly pass through the silica gel, with sufficient heating and high thermal efficiency.
5.Multiple imported sensors are used to accurately display parameters such as the breather's own state, the working state of silica gel, the internal and external temperature and humidity of the oil conservator pipeline, and the breathing state and flow rate.
6.The operating status of the equipment can be adjusted based on built-in parameters such as geographical location and environmental temperature and humidity. In the later stage, it can be expanded to connect to a meteorological server to adjust the operating strategy in advance for severe weather such as cold waves and continuous rainy days.
7.Through algorithm upgrades, high level analysis of the collected data can be carried out to analyze and evaluate the transformer's breathing state, the moisture absorbing capacity of silica gel, and the risk of capsule failures.
