Accompanying drawing explanation
Fig. 1 is the outboard structure schematic diagram of the utility model embodiment door body;
Fig. 2 is the inside structure schematic diagram of the utility model embodiment door body.
Embodiment
Below in conjunction with the drawings and specific embodiments, detailed construction of the present utility model is further described.
As depicted in figs. 1 and 2: a kind of explosion door for switch cabinet, the door lock 2 comprising a body 1 and be located on a body 1.The middle and upper part of door body 1 is provided with form 3, and form 3 is made up of two-layer toughened glass 31 and the protection network 32 be welded between toughened glass 31.This is because toughened glass 31 has good thermal stability, and its impact strength and bending strength are 3 ~ 5 times of simple glass; When toughened glass 31 is subject to the destruction of switch cubicle internal force, fragment can become the broken granule in similar cellular obtuse angle, not easily causes serious injury human body, to ensure the personal safety of operating personnel.Two-layer toughened glass 31 is installed on the internal layer of form 3 respectively with in the outer groove (not shown) offered, and fixes respectively by fixed head 33.Protection network 32 is woven by stainless steel wire material and forms, and be made up of surrounding edge 321 and silk screen 322, surrounding edge 321 is located at the surrounding of silk screen 322 and is embedded in groove, and the mesh form of silk screen 322 is rhombus; Surrounding edge 321 is made up of several triangles, and leg-of-mutton base embeds in groove.Protection network 32 can reinforce impact strength and the bending strength of toughened glass 31 further.The surrounding of groove digs out a rectangular slot, makes toughened glass 31 and surrounding edge 321 just in inserted into gap, by fixed head 33 fixation.Fixed head 33 is a rectangle framework, and fixed head 33 is fixed on outside and the inner side of a body 1 by six screws 331, is symmetrically distributed in the edge of fixed head 33, to guarantee the sealing of a body 1.The shape of two-layer toughened glass 31, protection network 32, fixed head 33, groove is identical, is rectangle.The present embodiment by offering form 3 on door body 1, and form 3 is made up of two-layer toughened glass 31 and the protection network 32 be located between toughened glass 31, has both strengthened explosion-proof and the sealing of a body 1, can directly grasp situation in cabinet again, easy to operate.
Door lock 2 is indoor electromagnetic lock, and model is DSN-DM/Z, is embedded at the lower right side of a body 1.The front portion of door lock 2 is provided with power supply indicator 21, indicator light 22 of unblanking, three-phase indicator light 23 and handle 24; The back of door lock 2 is provided with terminals 25.Door lock 2 built-in sensors, for detecting high-voltage signal, and indicates three-phase high-voltage charged state respectively by three-phase indicator light 23.The inner side of door body 1 is provided with cabling portion 4, and cabling portion 4 is the bar shape of two ends bending, and the two ends dogleg section of bar shape is welded in the inner side of a body 1, for the terminals 25 of door lock 2 being connected to the inside of switch cubicle.The quantity in cabling portion 4 is four, and the bottom of form 3 is arranged with three cabling portions 4, and the side of form 3 is provided with a cabling portion 4, from the downside binding cabling of bar shape, also can bind cabling from bar shape, can also carry out binding cabling through bar shape.
The operation principle of the present embodiment door lock 2 is: after passing into operating voltage, and power supply indicator 21 is bright, and three-phase indicator light 23 does not work, and illustrate that high tension loop is not charged, this state allows to unblank; Forward handle 24 to position to rightabout of unblanking, press electromagnetic lock button, indicator light 22 of unblanking is bright, and turning handle 24 can be unblanked; If unblank, indicator light 22 does not work, and three-phase indicator light 23 is bright, then represent and can not unblank.The door lock 2 of the present embodiment has charged instruction and forced blocking function, thus reliably prevents electric misoperation and mistakenly entering charged chamber, to protect personal safety.
