Description
Technical field
The utility model belongs to indoor electrical control complete set of equipments field, relates to a kind of explosion-proof observation window specifically.
Background technology
At electrical power distribution electrical domain, for reducing the loss of delivery of electrical energy, usually adopt voltage levels transmission.For convenience of operation and controlling, 35kV and following high pressure power transmission and distribution interval are often designed to indoor complete mode, and repair and maintenance personnel can complete the control of element, the interlock of equipment, the measurement etc. of table meter under comparatively comfortable environmental condition.But high-grade because of its voltage strength of indoor high-voltage complete set of equipments, easily the electric shock that can not save is caused to the person, therefore indoor high-voltage equipment needs to design tight reliable shell protection, and the performance such as intensity, high temperature resistance, anticorrosive, tightness all needs to meet corresponding requirements.
The main part of indoor high-voltage complete set of equipments is set up main point two large classes at design and cloth, and a class is for the secondary device manipulated with show, and another kind of be the primary device of delivery of electrical energy, distribution and control.Secondary device electric pressure is low, as long as human body does not touch alive circuit, generally shock phenomenon can not occur.The situation of primary device is just completely different, because high voltage exists over the ground, even if human body does not touch electrified body, if the distance of human body and electrified body is less than certain numerical value, still can produce electric discharge casualty accident.Therefore the requirement of shelter of primary device is strict, and should ensure the safe spacing of the person, also will set electric insulation level.
First and second device of high pressure complete set of equipments is of equal importance on Function and operation, and no matter which class device breaks down, and whole complete set of equipments system all will be paralysed.Therefore the groundwork of maintenance of electric device maintainer and task are exactly under the normal operation of equipment, strengthen patrolling and examining and safeguarding first and second device of equipment, pinpoint the problems early, take measures on customs clearance thus the expansion of control accident.Complete set of equipments secondary device in the past can easily from screen External Observation, maintenance, but primary device is because being sealed in protective casing, running cannot monitor and observe, the operation conditions of device cannot be monitored and intervene in advance, until device damages, just found during system shutdown.
Along with the progress in epoch, people recognize that the function ratio secondary device of primary device is more important gradually, the on-line monitoring that it is run and the visual inspection of external imagery essential.For visual inspection is to the equipment in close protection housing, during complete set of equipments housing design, need to arrange observation window at object being observed correspondence position, operation maintenance personnel just can see the ruuning situation of interior arrangement by observation window when normally patrolling and examining, find that early stage, problem also can process in time, thus avoid the further expansion of accident.
For meeting the requirement of intensity and safety, the protective casing of complete set of equipments generally makes of metal material, and degree of protection and seal degree are all higher.Observation window for observing component arrangement is substantially all made up of glass, but this has often become link very weak together, causes the explosion accident of equipment, even injures personal safety.
Summary of the invention
In order to solve the problems of the technologies described above, the utility model provides a kind of tour requirement that can meet equipment repair and maintenance personnel, and has the explosion-proof observation window of function of safety protection.
The technical solution adopted in the utility model is: comprise guard shield, woven wire, glass and fixed mount, guard shield is provided with observation fenestra, described woven wire and the size of glass are greater than the size of observing fenestra, woven wire and glass are arranged on the guard shield at observation fenestra place by fixed mount, and woven wire is positioned at the outside of glass.
In above-mentioned explosion-proof observation window, described woven wire and glass are arranged on the medial surface of guard shield by fixed mount, and woven wire is between glass and guard shield.
In above-mentioned explosion-proof observation window, described observation fenestra outer rim place is welded with bolt, and fixed mount is fixed on the medial surface of guard shield by nut.
In above-mentioned explosion-proof observation window, described observation fenestra is rectangle, and described woven wire and glass are also rectangle; Described fixed mount is the Z-shaped string configuration in cross section.
Compared with prior art, the beneficial effects of the utility model are:
The utility model is when high pressure complete set of equipments internal gas pressure intensity raises, weak frangible glass is under the supporting role of woven wire, ensure that its compression strength, deformation failure can not be produced, more can not burst, compression strength is far above the compression strength of pressure relief device, thus ensure that normally opening and the timely release of pressure of pressure relief device, prevent the generation of explosion accident, not only meet the tour requirement of equipment repair and maintenance personnel, and have function of safety protection, personal life security can have been ensured.Fixed mount is fixed on guard shield by nut by the utility model, thus fixing glass and woven wire, there is dismounting and change advantage easily.
Accompanying drawing explanation
Fig. 1 is front view of the present utility model.
Fig. 2 is end view of the present utility model.
In figure: 1, guard shield; 2, fenestra is observed; 3, glass; 4, woven wire; 5, fixed mount; 6, bolt.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further described.
As shown in Figure 1, 2, the utility model comprises guard shield 1, woven wire 4, glass 3 and fixed mount 5, it also can be other shapes that guard shield 1 is provided with rectangular observation fenestra 2(, such as circular), edge's guard shield 1 medial surface of observation fenestra 2 is welded with bolt 6, fixed mount 5 is arranged on guard shield 1 medial surface by nut, and woven wire 4 and glass 3 are pressed on by fixed mount 5 to be observed on fenestra 2 place guard shield 1 medial surface.Described woven wire 4 and glass 3 are rectangle (also can be other shapes, such as circular), and described woven wire 4 and the size of glass 5 are greater than the size of observing fenestra 2, and woven wire 4 is between glass 3 and guard shield 1; Described fixed mount 5 is the Z-shaped list structure in cross section.When woven wire 4 and glass 3 are other shapes, the shape of fixed mount 5 changes accordingly, and such as, when woven wire 4 and glass 3 are rounded, fixed mount 5 is the Z-shaped circulus in cross section.
Woven wire 4 thickness that the utility model adopts is 4mm, and the thickness of glass 3 is 5mm.When the utility model uses, when high pressure complete set of equipments internal gas pressure intensity raises, weak frangible glass 3 is under the supporting role of woven wire 4, ensure that its compression strength, deformation failure can not be produced, more explosion can not be formed, compression strength is far above the compression strength of pressure relief device, thus ensure that normally opening and the timely release of pressure of pressure relief device, prevent the generation of explosion accident, not only meet the tour requirement of equipment repair and maintenance personnel, and have function of safety protection, personal life security can be ensured.If glass 3 damages under other abnormal conditions, due to its detachability flexibly, attendant can change quickly and easily, greatly meets the multiple requirements of user.
