Description

Technical Field

[0001] The utility model relates to the technical field of mutual inductors, in particular to a mutual inductor with high safety. Background Art

[0002] A mutual inductor is an electrical device used to measure the interaction between currents or voltages. It is a transformer that converts changes in current or voltage into output signals through the principle of electromagnetic induction. A mutual inductor usually consists of two or more coils, one of which is connected to the power circuit, called the main coil, and the other is connected to the load circuit, called the secondary coil. When the current or voltage in the main coil changes, it causes an induced electromotive force in the secondary coil, thereby generating an output signal. Mutual inductors are widely used in power systems, electric energy metering, and power transmission.

[0003] However, the structure of the transformer in the prior art is relatively simple. The transformer is usually used in the working environment of industrial equipment and is easily affected by the vibration and impact of the industrial equipment, which makes the internal components of the transformer easy to be damaged, affecting the normal use of the transformer and having poor safety performance. At the same time, most transformers are not equipped with alarm devices. When the current inside the transformer exceeds or falls below a certain value, it cannot automatically issue an alarm or power off, causing the transformer to be easily damaged. In order to solve the above problems, we propose a transformer with high safety. Utility Model Content

The rubber plate 204 and the elastic rod 205 are located on both sides of the insulating base 203.

[0028] The sensing component 104 includes a current sensor 1041 and an alarm 1042. The current sensor 1041 is fixed to the top of one side of the transformer body 102, the alarm 1042 is fixed to the top of one side of the protective shell 101, and the input end is unidirectionally electrically connected to the output end of the current sensor 1041.

[0030] Example 2

[0031] Reference Figure 1-4 , which is the second embodiment of the utility model, and this embodiment is based on the previous embodiment.

[0032] Ventilation holes are provided on both sides of the inner cavity of the protective shell 101, a dustproof net is fixedly connected to the inner cavity of the ventilation hole, a waterproof inclined plate 3 is fixedly connected to one side of the ventilation hole, a limiting block is fixedly connected to the top of the sliding sleeve 2062, a limiting groove is provided on the top of the inner cavity of the protective box 202, the surface of the limiting block is slidably connected to the inner cavity of the limiting groove, and the surface of the transformer body 102 is coated with waterproof material, and the material of the waterproof material is a polymer coating.

[0034] The working principle of the utility model is as follows: when the transformer equipment works in an environment where industrial equipment gathers, the industrial equipment will generate vibration and impact force. First, the vibration is transmitted to the outer surface of the protective shell 101, and the elastic rod 205 will expand and contract to squeeze the rubber plate 204 due to the vibration, and the transformer body 102 is damped by the elasticity of the elastic rod 205 itself. When the vibration is transmitted to the bottom of the transformer, the damper 201 will swing up and down, and the damper 201 will dampen it by its own damping property. At the same time, the support rod 2064 is vibrated, and the vibration causes the sliding sleeve 2062 at one end of the support rod 2064 to slide on the surface of the fixed rod 2061, and the sliding sleeve 2062 squeezes the spring 2063, and the spring 2063 uses its own elastic rebound to dampen the shock, so that the transformer body 102 can be protected. When the current inside the transformer body 102 exceeds or is lower than the set threshold, the current sensor 1041 transmits a signal to the alarm 1042, and the alarm 1042 sends an alarm to remind the maintenance personnel.
