Abstract
The utility model relates to a power supply device. A high-frequency switching power supply AC screen shield door mainly includes a high-frequency switching power supply AC screen frame, with a glass shield door arranged on the AC screen frame. The glass shield door is assembled by a metal doorframe and a glass door made of the safe anti-explosive thick glass. The place between the glass door and the metal doorframe is compressed by using a rubber sealing strip, while the place between the metal doorframe and the AC screen frame and the inner side of the metal doorframe is provided with a magnetic sealing strip. The glass shield door arranged before the high-frequency switching power supply AC screen frame provides a good protection to prevent the exposed elements on the screen surface from being corroded, thereby improving the protection degree of the screen frame greatly, so as to meet the severe environment with dust and splash. In addition, because of the separation by using the wide glass door, the artistic appearance makes no effect on the monitoring of the operators and furthermore prevents the operation fault.
Description
Affiliated technical field
The utility model relates to power supplying and distributing equipment, refers to the power-supply device for power distribution equipment that transformer station, power plant use especially, specifically refers to a kind of shield door structure of high frequency switch power direct current cabinet.
Background technology
High frequency switch power is a kind of device that civil power is transformed into the DC power supply of using for, panel switches cabinet.The vertical screen shelf structure of general employing is called the high frequency switch power direct current cabinet.The screen frame adopts the standardization member, is easy to combination, highly versatile, and installation is quick and labour intensity is low.But the components and parts on this high frequency switch power direct current cabinet panel are exposed in the various abominable environments for use throughout the year, owing to without any protection, be subjected to the pollution of environment and dust easily.
Summary of the invention
The purpose of this utility model provides a kind of high frequency switch power direct current cabinet shield door, and this shield door of mat overcomes the deficiencies in the prior art to the protection of direct current cabinet.
A kind of high frequency switch power direct current cabinet shield door of the present utility model mainly comprises a high frequency switch power direct current cabinet frame, it is characterized in that described direct current cabinet frame is provided with a glass shield door
Described shield door is assembled by metal door frame and glass door, this glass door adopts the safety anti-explosive heavy sheet glass to make, adopt rubber weather strip to compress between glass door and metal door frame, metal door frame and direct current cabinet shield between the frame, the inboard of metal door frame is provided with magnetic refrigerator sealing strip.
Advantage of the present utility model is, owing to before high frequency switch power direct current cabinet screen frame, be provided with the glass shield door, good protective action is arranged, can protect the components and parts that expose on the panel not weather, the protection class of screen frame is greatly improved, can satisfy dust big, the adverse circumstances that dabble are arranged; Because adopt roomy glass door to isolate, not only outward appearance seems attractive in appearance, do not influence the operation operations staff and monitor, can also prevent misoperation.
