Description
Technical field
The utility model relates to electrical equipment fields, more specifically to explosion-proof electrical distribution box.
Background technique
Distribution box is the important component in electric wiring, and distribution box is the transit point of electric wiring, wherein will be installed various
Switch, control and protection device.For security consideration, distribution box would generally use enclosed structure, by various components with
And closure of track is in distribution box.The explosion-proof electrical distribution box used in inflammable and explosive or low-temperature cold environment is even more to mention for sealing
Go out very high requirement, explosion-proof electrical distribution box interior or exterior space is completely isolated, on the one hand need explosive dust, gas outside preventing
Body, water etc. do not enter inside distribution box, on the other hand to prevent the electric spark generated in internal electric route operational process will not
Leak into outside.For the ease of the state of each component in observation distribution box, on distribution box needs that visual windows are arranged, pass through
Visual windows are observed that the state of the component inside explosion-proof electrical distribution box.
The visual windows of distribution box are generally located on the panel of distribution box, in the higher field of seal request, on panel
Visual windows seal request it is equally very high, therefore can ensure panel and visual windows component using more complicated structure
Between sealing.
Fig. 1 discloses the cross section structure figure of the panel of the explosion-proof electrical distribution box used in the prior art.Refering to what is shown in Fig. 1, existing
The panel for having the explosion-proof electrical distribution box in technology includes: panel pedestal 102, upper cover 104, transparent panel 106 and one group of sealing ring.Panel
Pedestal 102 is mounted on the cabinet of explosion-proof electrical distribution box and (cabinet of explosion-proof electrical distribution box is not shown in Fig. 1).Upper cover 104 is rotatablely installed
On panel pedestal, in the illustrated embodiment, upper cover 104 is rotatably installed on panel pedestal by shaft.Upper cover 104 is beaten
It opens, then the cabinet of explosion-proof electrical distribution box is open, can operate to the component in explosion-proof electrical distribution box.Upper cover 104 close, then on
Lid 104 and panel pedestal 102 close explosion-proof electrical distribution box, and the component in explosion-proof electrical distribution box is closed in explosion-proof electrical distribution box.
Since the seal request of explosion-proof electrical distribution box is higher, upper cover 104 and panel pedestal 102 need to carry out explosion-proof electrical distribution box effective close
Envelope.For the ease of the state of each component in observation and explosion-proof distribution box, transparent panel 106 is provided in upper cover 104, by saturating
Isotropic disk 106 is observed that the state of each component in explosion-proof electrical distribution box.In general, corresponding to component in upper cover 104
Position can open up window, transparent panel 106 is just mounted on the position of window.The size and explosion-proof power distribution of window and transparent panel 106
Arrange that the size in the region of component matches in case.For example, in the embodiment shown in fig. 1, in upper cover 104 is located substantially at
The position in portion has opened up window, is mounted with transparent panel 106 in the position of window, on the size of window and transparent panel 106 is about
The half of size or so of lid 104.In the illustrated embodiment, transparent panel 106 is glass, and transparent panel 106 is mounted on upper cover 104
Window on, a block pressur plate 108 is installed again above transparent panel 106, transparent panel 106 is securely fixed in upper cover 104.
Since explosion-proof electrical distribution box is integrated with higher seal request, it is also required between upper cover 104, transparent panel 106 and pressing plate 108
Reliably sealed.In the illustrated embodiment, three sealing rings has been used to be sealed.The setting of first sealing ring 111
Between upper cover 104 and pressing plate 108, for the sealing between upper cover and pressing plate.Second sealing ring 112 is arranged in 104 He of upper cover
Between transparent panel 106, for the sealing between upper cover and transparent panel.Third sealing ring 113 is arranged in transparent panel 106 and pressing plate
Between 108, for the sealing between transparent panel and pressing plate.In the prior art, the panel needs of explosion-proof electrical distribution box are used to five classes
Component: panel pedestal, upper cover, transparent panel, pressing plate and sealing ring, wherein the quantity of sealing ring is several.In explosion-proof electrical distribution box
When component number is more or subregion is needed to be arranged component, in order to obtain bigger effective area region, also
It needs to open up multiple windows, the multiple transparent panels of configuration on upper lid and uses corresponding pressing plate and sealing ring.It allows for matching in this way
The number of components for determining the panel of case is more, complex when being assembled.Also, it is more at the assembly connection of multiple components,
It is required to be sealed using sealing ring.When quantity is more at assembly connection, it is easy due to sealing ring aging or assembler
Skill problem and the case where generate poor sealing.
