Description

Technical Field

[0001] The utility model belongs to the technical field of electric power equipment, in particular to a voltage stabilizer with a dustproof structure. Background Art

[0002] A voltage stabilizer is a power supply circuit or power supply equipment that can automatically adjust the output voltage. Its function is to stabilize the power supply voltage that fluctuates greatly and does not meet the requirements of electrical equipment within its set value range, so that various circuits or electrical equipment can work normally under the rated working voltage. It is widely used in industrial and mining enterprises, oil fields, railways, construction sites, schools, hospitals, post and telecommunications, hotels, scientific research and other fields.

[0003] When the operator needs to adjust the voltage within the rated range, a voltage stabilizer is required. The existing voltage stabilizer consists of a voltage stabilizer body, a control panel, a switch and an alarm light. Although it can meet the basic voltage stabilization needs, in actual application, most of the existing voltage stabilizers are not equipped with dustproof screens, which causes external dust to easily pass through the vents into the interior of the voltage stabilizer, causing pollution to the interior of the voltage stabilizer. Over time, the internal electronic components are damaged, affecting the normal operation of the voltage stabilizer, so improvements are made to it. Utility Model Content

This satisfies the requirement that the device has good stability and is easy to move, thereby improving the practicability of the device. BRIEF DESCRIPTION OF THE DRAWINGS
