Abstract
It the utility model is related to a kind of explosion-proof observation window construction, including the window being opened on front door of switch cabinet, layer of transparent plate is fixedly installed on the inside of front door in the window's position, one block of safety glass is fixedly installed on the inside of transparent panel, the outer rim of the safety glass and transparent panel is enclosed with metal otter board.The utility model is realized in the case of internal arc occurs for switch cubicle by limiting the external influence of internal fault, personnel is provided with security protection as high-grade as possible.
Description
Technical field
The utility model belongs to transmission ＆ distribution electro-technical field, is related to observation window, especially a kind of to be used for metal armored movable
Sealing switch equipment is (referred to as：Switch cubicle) on explosion-proof observation window.
Background technology
When switch cubicle is in charging operation state, when Internal faults arc occurs for switch cubicle, because it produces powerful height
Temperature, high-voltage arc impact force action door in switch cubicle, make the observation window scaling loss being installed on middle door, cause hot gas to be released suddenly
Put, then security incident may be triggered to cause personal injury to live operation maintenance personnel.
Utility model content
The shortcomings that the purpose of this utility model is to overcome above-mentioned prior art, there is provided a kind of explosion-proof observation window, it passes through
The external influence of internal fault is limited, is realized in the case of internal arc occurs for switch cubicle, personnel are provided as high-grade as possible
Security protection.
The purpose of this utility model solves by the following technical programs：
This explosion-proof observation window construction, including the window being opened on front door of switch cabinet, in the window's position in front door
Side is fixedly installed layer of transparent plate, is fixedly installed one block of safety glass on the inside of transparent panel, the safety glass and thoroughly
The outer rim of isotropic disk is enclosed with metal otter board.
Above-mentioned transparent panel is identical with the area size of safety glass.
Above-mentioned transparent panel is polycarbonate plate or glass plate.
The thickness of above-mentioned transparent panel is 6mm.
The thickness of above-mentioned safety glass is 10mm.
The thickness at above-mentioned front door is 2mm.
Above-mentioned metal otter board passes through switch cabinet body or wired earth.
The utility model has the advantages that：
Explosion-proof observation window construction of the present utility model is easy for installation, simple in construction, safe and reliable, has equal with shell
Mechanical strength properties, reliable explosion-proof performance, good fire resistance and antistatic performance, by pair for limiting internal fault
Outer influence, realize the security protection to personnel in the case of internal arc occurs for switch cubicle.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Wherein：1 is metal otter board；2 be safety glass；3 be transparent panel；4 be front door of switch cabinet.
Embodiment
The utility model is described in further detail below in conjunction with the accompanying drawings：
Referring to Fig. 1：This explosion-proof observation window construction includes the window 4.1 being opened on front door of switch cabinet 4, in window 4.1
Position is fixedly installed layer of transparent plate 3 in the inner side of front door of switch cabinet 4, and one block of steel is fixedly installed in the inner side of transparent panel 3
Change glass 2, the outer rim of the safety glass 2 and transparent panel 3 is enclosed with metal otter board 1.Wherein transparent panel 3 and safety glass 2
Area size is identical.
In the utility model, transparent panel 3 is polycarbonate plate or glass plate, preferably polycarbonate plate.Metal otter board 1 is logical
Cross switch cabinet body or wired earth.
Most preferred embodiment of the present utility model given below：
Metal otter board 1：Material selection thickness is made up of 2mm metal otter board, is directly grounded with switch cabinet body, has very
Good antistatic performance, in switch cubicle normal operation, can be effectively prevented from because electrostatic induction discharges what is brought to operating personnel
Harm.
Safety glass 2：Material selection thickness is made up of 10mm tempered glass materials, and surface stress is not less than 80MPa, resistance to
Caloric impact temperature is not less than 120 DEG C, has good explosion-proof performance, will not be because of electric arc impact power when arcing occurs inside cabinet
The glass disintegrating slag with wedge angle is produced, can effectively reduce the harm brought to operating personnel.
Transparent panel 3：Material selection thickness is made up of 6mm makrolon material, and surface stress is not less than 110MPa, has
Heat resistance well, its continuous heat resisting temperature are 140 DEG C~141 DEG C, can meet that the temperature of the accessible shell of switch cubicle will
75 DEG C (40 DEG C of+30K) (30K is the temperature rise of the accessible shell of switch cubicle) is asked, polycarbonate flame retardant rating can reach UL94V-
0, there is good fire resistance, belong to self-extinguishing.Therefore, when arcing occurring inside cabinet, it is existing that burning will not be brought it about
As that can be effectively prevented from because hot gas discharges, the harm brought to operating personnel.
It should be noted that above example is only unrestricted to illustrate the technical solution of the utility model, although ginseng
The utility model is described in detail according to preferred embodiment, it will be understood by those within the art that, can be to this
The technical scheme of utility model is modified or equivalent substitution, without departing from the spirit and model of technical solutions of the utility model
Enclose.
