American Transformer Accessory Kit (4 Parts): Reliable Transformer Gauges for Oil-Immersed Transformers-part1

Let’s take a look at the 4-piece kit for American-style transformers.

First up: UHZ-01 Oil Level Indicator for Transformer. This is the transformer oil level indicator.

A UHZ-01 Oil Level Indicator for Transformer

Application:

The oil level indicator is applicable to the oil tank installed on the side wall of small and

medium-sized oil immersed transformer oil conservators and on load switch oil conservators. The oil level indicator can also be used for liquid level measurement of other open or pressure

vessels, and can replace the connected glass tube oil level indicator.

Conditions:

Temperature: – 40℃~80℃

Humidity: ≤90% in 25℃

Altitude: ≤2000m

Vertical installation

Structure and working principle:

The oil level indicator is composed of a float, connecting rod, gauge base and magnetic steel pointer.

When the oil in the conservator increases or decreases due to temperature or other factors, the float of the oil level gauge increases or decreases synchronously with the oil level, so as to drive the

pointer to rotate and indicate the level of the oil level.

Notes:

1. Without being strongly impacted.

2. The connecting rod without a bend, and without magnetism when it starts working.

3. The sealing ring should be sealed with the panel

Mounting dimensions:

Next, we have the AYZ70 Pressure Vacuum Gauge.

A YZ 70 Pressure Vacuum Gauge

Structure and working principle:

The pressure/vacuum gauge indicates whether the gas space in the tank is under positive or negative pressure. The pressure will vary depending on the transformer

temperature.

Technical:

Measuring range: -0.04～0.04 MPa

Accuracy: class 2.5

Temperature: – 40℃~80℃

Humidity: ≤90%

Diameter: Ф70

Joint: M27×2 bolt

Use and maintenance:

Vertical installation

Measuring range limit in ±3/4

Tighten the compression bolt

Handle gently

Regular inspection within 6 months
