Scientific and technological innovation and new life
Specializing in the production of various El transformers, voltage rise and fall transformers, ring transformers, SG three-phase and DG single-phase dry-type transformers, regulated power supplies, special transformers
Occupying a very important position in the power transmission and distribution system, it is required to operate safely and reliably. When the Low price control transformer is damaged during operation, it will cause a power outage. It is usually used in machine tools and mechanical equipment as the power supply of electrical control lighting and indicator lights, and is used to provide power for the control part of the electrical circuit.
Today I will introduce you the security requirements of quality control transformer.
1. Insulation resistance
The insulation resistance of the control transformer in the cold state should not be lower than 10 MΩ; the insulation resistance of the control transformer in the hot and damp state should not be lower than 2 MΩ.
What should be paid attention to when using quality control transformer?
When using the control transformer, two points should be paid attention to: one is the power of the transformer, and the other is correct wiring. The total power of the load connected to the secondary side (secondary) shall not exceed the power of the control transformer, and short circuit is not allowed.
Today, I will answer a few questions about the control transformer.
What is a Control Transformer?
In the low-voltage power distribution system, the control transformer gets its name because it is mostly used in the control system. It is actually a step-down transformer with multiple output voltages, and can also be used as a power supply for low-voltage lighting, signal lights, and indicator lights.
