Abstract
The utility model relates to low-voltage power transmission and distribution equipment, in particular to an arcing pressure relief device for a low-voltage power distribution cabinet. The arcing pressure relief device for the low-voltage power distribution cabinet comprises a cabinet body of the power distribution cabinet, wherein the top of the cabinet body is provided with a pressure relief port; an upper cover is covered on the pressure relief port; the edge of the pressure relief port is provided with an installation support plate; the installation support plate is provided with an installation hole; meanwhile, a bolt which is fixedly connected with the upper cover and is vertical to the upper cover is arranged at a position at the bottom of the upper cover which is opposite to the installation hole; the lower end of the bolt passes through the installation hole, and is connected with a nut in a matching way; a spring is sleeved on a bolt between the nut and the installation support plate; and the nut is pressed against the installation support plate through the spring. The arcing pressure relief device has a simple structure, and is convenient to manufacture and install; after the arcing pressure relief device is arranged, the protection level of a switch cabinet is not lowered; when a large pressure is formed in the cabinet due to arcing, the upper cover can be jacked up by avoiding spring force under the action of an air pressure, so that pressure is successfully relived from the pressure relief port, and the aim of preventing the cabinet body from being damaged by compression is fulfilled.
Description
Technical field
The utility model relates to the low pressure equipment for power transmission and distribution, specifically is a kind of low-voltage distribution cabinet arcing pressure relief device.
Background technology
When being short-circuited the arcing fault in the low-voltage distribution cabinet, meeting is moment generation high temperature, high pressure in cabinet; If the power distribution cabinet degree of protection is higher, like IP54, then this pressure can't be discharged into outside the cabinet smoothly, may cause the permanent modification of cabinet, even the cabinet door is blown up.Generally speaking, no special pressure relief device in the low-voltage distribution cabinet, thereby be in operation and have hidden danger.
Summary of the invention
The utility model technical problem to be solved is, a kind of timely release pressure during the arcing fault that can in power distribution cabinet, be short-circuited is provided, and damages low-voltage distribution cabinet arcing pressure relief device simple in structure simultaneously, as not reduce degree of protection to avoid cabinet.
The low-voltage distribution cabinet arcing pressure relief device of the utility model includes the cabinet of power distribution cabinet, has a pressure relief opening at the cabinet top, on pressure relief opening, is stamped a loam cake; Said pressure relief opening edge is provided with the installation support plate, support plate is installed is provided with installing hole, is provided with in the position relative with installing hole, loam cake bottom simultaneously to be fixedly connected with loam cake and perpendicular to the bolt of loam cake; The bolt lower end is passed installing hole and is connected with nut, on the bolt between nut and the installation support plate, is with spring, and nut is pressed in through spring and installs on the support plate.
Said pressure relief opening is a rectangle, and said installation support plate is arranged on four bights of pressure relief opening.
The utility model is simple in structure, manufacturing and easy for installation; After installing, it does not reduce the degree of protection of switch cubicle; When producing big pressure owing to arcing in the cabinet; Air pressure can make loam cake overcome spring force and by jack-up, thereby through the smooth pressure release of pressure relief opening, to reach the purpose of avoiding the cabinet fail in compression.
