Description

Special lifting appliance for pouring coil of transformer with air channel

Technical Field

The utility model relates to a transformer technical field especially relates to a transformer takes gas channel pouring coil special lifting device.

Background

The transformer is a static electric appliance made by utilizing the principle of electromagnetic induction. When the primary coil of the transformer is connected to an ac power supply, an alternating magnetic flux, denoted by phi, is generated in the core. Phi in the primary coil and the secondary coil is the same, and phi is also a simple harmonic function, and the table is phi = phi msin omega t. According to the faraday's law of electromagnetic induction, the induced electromotive forces in the primary and secondary coils are e1= -N1d Φ/dt and e2= -N2d Φ/dt. In the formula, N1 and N2 are the number of turns of the primary coil and the secondary coil. The core functions to enhance the magnetic coupling between the two coils. In order to reduce eddy current and hysteresis loss in iron, the iron core is formed by laminating painted silicon steel sheets, and two coils are not electrically connected and are wound by insulated copper wires (or aluminum wires). One coil is connected with an alternating current power supply and is called a primary coil (or a primary coil), and the other coil is connected with an electric appliance and is called a secondary coil (or a secondary coil). The actual transformer is complex and inevitably has copper losses (coil resistance heating), iron losses (core heating) and leakage (magnetic flux lines closed by air), etc., and only the ideal transformer will be described here for simplicity of discussion. The ideal transformer holds the following conditions: the leakage flux, the resistances of the primary and secondary coils, the core loss, and the no-load current (the current in the primary coil with the secondary coil open) were neglected. For example, when the power transformer runs in full load (the secondary coil outputs rated power), the situation is close to the ideal transformer;

the existing lifting appliance is inconvenient to move transformers with different widths when moving the transformers, and is poor in applicability, so that a special lifting appliance for pouring coils of the transformers with air channels is provided to solve the problems.
