Direct current speed regulation cabinet for ship thyristor reversible direct current speed regulation control system

Abstract

The invention discloses a direct current speed regulation cabinet for a ship thyristor reversible direct current speed regulation control system, which comprises a shell and a partition plate, the top surface of the shell is not closed, the partition plate is fixedly connected to the position, close to the right side, of an inner cavity of the shell, a cover plate is arranged on the upper side of the shell, and a host is fixedly connected to the position, close to the left side, of the bottom surface of the cover plate. The cover plate is provided with a movable mechanism on the right side of the partition plate. By arranging the exhaust mechanism, rotation of fan blades can be achieved through driving of the motor, exhaust operation on the inner cavity of the shell is achieved, air flow in the inner cavity of the shell is accelerated, the stability of the host is effectively reduced, and the heat dissipation effect is good; and by arranging a baffle and a side plate, the side plate and the baffle can ascend under the buoyancy action of water, so that the baffle can seal the rectangular groove, a water source is prevented from entering the shell, and the protection performance is improved. The LED lamp has the advantages of being high in protection performance and good in heat dissipation effect.

Description

technical field [0001] The invention relates to the technical field of DC speed control cabinets, in particular to a DC speed control cabinet for a marine thyristor reversible DC speed control system. Background technique [0002] Thyristor is a switching element that can work under high voltage and high current conditions, and its working process can be controlled and is widely used in electronic circuits such as controllable rectification, AC voltage regulation, non-contact electronic switches, inverters and frequency conversion. It is a typical device that controls large current with small current. In the prior art, the thyristor reversible DC speed control system is used on ships, which greatly improves the reliability of ships. The prior art thyristor reversible DC speed control system is installed in the DC speed control cabinet. The prior art DC speed control cabinet has poor airtightness, and the humidity on the ship is relatively high, which easily causes the DC spe...

AI Technical Summary

Problems solved by technology

The thyristor reversible DC speed control system in the prior art is installed in the DC speed control cabinet. The airtightness of the DC speed control cabinet in the prior art is poor, and the humidity on the ship is high, which easily causes the DC speed control cabinet to contact the water source. As a result, the system is damaged, which is not conducive to use. In addition, the thyristor reversible DC speed control system in the prior art lacks good heat dissipation measures, which makes it easy to be damaged due to high temperature after use, which reduces the stability of use. , which is the shortcoming of the existing technology
