Which is better, dry-type test transformer or inflatable test transformer?

Dry type test transformers and inflatable test transformers have their own advantages and disadvantages, and the selection should be based on specific application scenarios and requirements:

① Advantages

a. High safety: using epoxy resin vacuum casting and CD magnetic core technology, oil-free design to avoid fire and explosion risks, especially suitable for places with strict fire prevention requirements.

b. Environmentally friendly and maintenance free: No need for insulation oil, no risk of oil leakage, low operation and maintenance requirements, and low long-term use costs.

c. Stable performance: High insulation strength, strong moisture resistance, suitable for insulation performance testing of electrical equipment in complex environments.

2. Advantages and disadvantages of inflatable test transformers

① Advantages

a. Lightweight and portable: Equipped with SF6 gas insulation, the volume and weight are significantly reduced, making it easy to transport and frequently move on site.

b. High insulation performance: SF6 gas has excellent electrical insulation and arc extinguishing capabilities, suitable for high-precision testing needs, such as factory testing or scientific research experiments of power equipment.

c. Environmental Protection and Safety: Oil free design avoids oil pollution, and SF6 gas is non flammable and non explosive, suitable for flammable and explosive environments or places with high safety requirements.

② Insufficient

a. High cost: The SF6 gas filling process is complex, and the equipment price and maintenance cost are relatively high.

b. High environmental sensitivity: High requirements for temperature, humidity, and other conditions of the usage environment, and SF6 gas leakage may cause pollution to the environment.

c. Difficulty in maintenance: If internal gas escapes, it needs to be returned to the factory for processing, and the maintenance process is complex and time-consuming.

3. Choose Suggestions

① The scenario where dry-type test transformers are preferred:

a. Indoor environments or places with high requirements for fire and explosion prevention.

b. Projects that require long-term stable operation and low maintenance costs.

c. Scenarios with strict requirements for environmental performance.

② Priority should be given to the scenario of using inflatable test transformers:

a. Scenarios that require frequent movement or on-site testing.

b. Places with strict restrictions on equipment weight and volume.

c. In situations where high-precision testing or high security requirements are needed.
