A kind of pressure release type box-type substation
Technical field
The utility model relates to a kind of pressure release type box-type substation.
Background technology
Along with improving constantly of scientific and technological level, higher safety requirements is proposed to high pressure outdoor electric appliances such as box-type substations.And for various reasons, in practical operation, occasionally have and high-pressure side arcing phenomenon occurs, and arcing phenomenon must discharge a large amount of energy, in this enclosure space of box-type substation, energy cannot be led off and cause the event of more havoc to happen occasionally.
Utility model content
The arcing phenomenon produced to overcome existing box-type substation easily produces operating personnel's personal safety and threatens, to the hurtful deficiency of equipment, the utility model aims to provide a kind of pressure release type box-type substation, this transformation station structure is by arranging pressure relief, effectively the energy that arcing phenomenon produces is discharged rapidly, thus support personnel and device security.
To achieve these goals, the technical scheme that the utility model adopts is:
A kind of pressure release type box-type substation, comprise cabinet and the cover plate being contained in cabinet top, between described cabinet and cover plate, baffle plate is housed, is provided with out the pressure release passage at cabinet sidewall between baffle plate and cover plate, the outlet of this pressure release passage is positioned at the ventilating opening place of cabinet; The pressure of described baffle plate in cabinet makes cabinet inner chamber be communicated with pressure release passage when exceeding set point.
Thus, when equipment normally runs, cabinet inner chamber body and pressure release passage are isolated by baffle plate; When arcing phenomenon produces, the energy of its generation is instantaneous washes baffle plate open, then discharges rapidly in pressure release passage, thus support personnel and device security.
Be below the technical scheme of further improvement of the utility model:
Preferably, described baffle plate is arranged on cabinet top by plastics screw, and when pressure limit, the plastics screw of baffle plate comes off, and baffle plate is rushed to open and is communicated with cabinet inner chamber and pressure release passage.
Above structure, the utility model, not affecting while box-type substation normally uses, when arcing accident occurs in box-type substation high-pressure side, can be led off safely to fall to release energy, protection life and device security.
Compared with prior art, the beneficial effects of the utility model are: the utility model fail safe is high, effectively protect equipment and personal safety.
Below in conjunction with drawings and Examples, the utility model is further elaborated.
Accompanying drawing explanation
Fig. 1 is the structure principle chart of the utility model embodiment;
Fig. 2 is the right view of Fig. 1.
In the drawings
1-cabinet; 2-pressure release passage; 3-ventilating opening; 4-observation window; 5-cover plate; 6-baffle plate.
Embodiment
A kind of pressure release type box-type substation, as illustrated in fig. 1 and 2, comprise cabinet 1 and the cover plate 5 being contained in cabinet 1 top, between described cabinet 1 and cover plate 5, baffle plate 6 is housed, this baffle plate 6 is arranged on cabinet 1 top by plastics screw, between baffle plate 6 and cover plate 5, be provided with out the pressure release passage 2 at cabinet 1 sidewall, the outlet of this pressure release passage 2 is positioned at ventilating opening 3 place of cabinet 1; Described baffle plate 6 moves upward when cabinet 1 internal pressure exceedes set point and cabinet 1 inner chamber is communicated with pressure release passage 2.
Thus, the utility model arranges increase by one group of pressure release passage at the top of box-type substation high-voltage board, directly lead to the ventilating opening of box-type substation shell, the fixed closed screw of high-voltage board top flap changes plastics pressure-relief explosion-proof screw into, when high-voltage board has an accident, the pressure of arcing release can strut the plastics screw at high-voltage board top, energy is directly discharged from the ventilating opening box-type substation by pressure release passage, ensure operator safety, avoid leading off nowhere due to pressure and damaging operator from the handle hole ejection of operating surface, avoid causing secondary damage to controller switching equipment simultaneously.
The content that above-described embodiment is illustrated should be understood to these embodiments only for being illustrated more clearly in the utility model, and be not used in restriction scope of the present utility model, after having read the utility model, the amendment of those skilled in the art to the various equivalent form of value of the present utility model has all fallen within the application's claims limited range.
