Description

Multi-function capacitor with switch

technical field

The utility model relates to a multifunctional capacitor with a switch for starting an electric motor.

Background technique

As a device that converts electrical energy into mechanical energy, an electric motor needs a capacitor that matches the electric motor when it starts or runs, so that the motor can start or run smoothly. The current electric motors have different powers due to different occasions where they are used, and the required matching capacitors have various capacitances. This brings a lot of trouble to companies or personnel specialized in motor maintenance. Maintenance personnel need to bring a large number of capacitors with various capacitance values to meet the maintenance needs of different electric motors. For the company, maintenance personnel need to carry a large number of different capacitors. Not only is the maintenance personnel a heavy burden in terms of weight, but the company's capital is also a heavy burden. Sometimes, when there is no suitable capacitor at the repair site, the maintenance personnel have to connect several different capacitors in series and/or in parallel to achieve a similar capacitance to replace the original capacitor. In this case, multiple capacitors not only take up a lot of space, but are also not strong enough to break easily, posing potential failures. If you bundle several capacitors together with adhesive tape, you can achieve a firm purpose, but its appearance is not very elegant.

In order to solve the above-mentioned problems, relevant manufacturers have tried their best to find a solution, but no suitable design has been developed for a long time. Therefore, this problem is a problem that relevant manufacturers are eager to solve.

Based on the rich practical experience and professional knowledge engaged in the design and manufacture of such products for many years, the designer actively researched and innovated with the application of academic theories. After continuous research, design, and repeated trials and improvements, he finally created A utility model with real practical value.
