When shield, needs to open high-tension switch cabinet secondary chamber cabinet door, carry out repair and maintenance.However, in the design of high-tension switch cabinet, relay
Protective device is mounted in secondary chamber's cabinet door, and terminal block and secondary cable line are mounted in secondary chamber, and secondary cable line is connected to
The terminal block in protective relaying device and cabinet in cabinet door, due to the effect of secondary cable line pulling force, high-tension switch cabinet secondary chamber
Cabinet door is always automatically closed, and influences staff and overhaul in cabinet and upkeep operation, reduction working efficiency.Therefore, it is necessary to additional
Increase a staff Fu Zhe secondary chamber cabinet door, secondary chamber's cabinet door is prevented to be automatically closed, increases human cost.
Utility model content
The purpose of this utility model is to be directed to existing high-tension switch cabinet, and secondary chamber's cabinet door does not prevent its self closing device
Deficiency, and providing one kind preventing high-tension switch cabinet secondary chamber cabinet door self closing device, and the apparatus structure is simple, can prevent height
The cabinet secondary chamber cabinet door that compresses switch is automatically closed, and does not influence maintenance and the upkeep operation of staff, improves work efficiency.
Realizing the technical solution of the utility model aim is：
One kind preventing high-tension switch cabinet secondary chamber cabinet door self closing device, the cabinet of the device and high-tension switch cabinet secondary chamber
Badge connects, including isosceles trapezoid epoxy resin board, n shapes aluminium sheet, H-shaped aluminium sheet and the screw with nut；
The isosceles trapezoid epoxy resin board is device medium, is set respectively on the side of two waists of isosceles trapezoid epoxy resin board
There is mounting hole；
The n shapes aluminium sheet includes along the outside horizontal extension of the one of vertical edges of n shape aluminium sheets and integrally formed installation
Face, mounting surface are equipped with mounting hole；
The length of side of the long side of the H-shaped aluminium sheet is equipped with mounting hole；
The mounting surface of n shape aluminium sheets is fixed on by the screw with nut on the side of a waist of isosceles trapezoid epoxy resin board, h
Shape aluminium sheet is fixed on by the screw with nut on the side of another waist of isosceles trapezoid epoxy resin board.
Pyrocondensation gum cover compatible with its shape is wrapped up in the outside of the n shapes aluminium sheet and H-shaped aluminium sheet respectively, prevents metal from leading
Electricity.
The isosceles trapezoid epoxy resin board, class of insulation 10kV, thickness 6mm, short bottom side length 150mm, long bottom
Length of side 400mm, a height of 70mm, the long bottom edge of isosceles trapezoid epoxy resin board and the angle of its two waist are 30 degree ~ 45 degree.
Since there are an endways thin baffle, the n of the n shape aluminium sheets of utility model device in all high-tension switch cabinet secondary chamber
Type groove and thin baffle fit, N-shaped slot blocks the thin baffle of secondary chamber, in this way, a waist edge of isosceles trapezoid epoxy resin board is just
It is fixed on the thin baffle of secondary chamber.
Since all high-tension switch cabinet secondary chamber cabinet door is opened towards a left side, and there are horizontal door edge, H-shaped aluminium in secondary chamber's cabinet door
The H type slot of plate can be used for door along coordinating, and H-shaped aluminium sheet blocks the horizontal door edge of secondary chamber, in this way, isosceles trapezoid epoxy resin
Another waist edge of plate is secured in the cabinet door of secondary chamber.
When high-tension switch cabinet secondary chamber cabinet station door open after, due between secondary chamber's cabinet door and secondary chamber by the utility model
Device is fixed, and the angle that secondary chamber's cabinet door is opened is 120 degree, and professional is facilitated to be opened in high-tension switch cabinet secondary chamber completely
Open up work.
Utility model device is simple in structure, and high-tension switch cabinet secondary chamber cabinet door can be prevented to be automatically closed, be applied to
Multiple substation 10kV high-tension switch cabinet relay protection periodical inspections work, using effect is good, completely without increase professional
Secondary chamber's cabinet door is prevented to be automatically closed, so that it may to ensure that field operation is smoothed out.
