Abstract
The utility model relates to a device for integrating a desiccant storage box and a pressure release component which overcomes the problems that as the existing desiccant storage box is arranged in an air chamber of switch equipment, the installation and the disassembly are inconvenient, and as an explosion-proof membrane is not provided with a protective hood, personnel is easy to damage. The utility model adopts the technical scheme that the device comprises a pressure release component and a flange; the flange is provided with a ladder type inner cavity along the direction of an axis; the desiccant storage box is installed in the ladder type inner cavity of the flange; and the protective hood with an opening on one side surface is installed at the upper end of an explosion-proof membrane clamping frame of the pressure release component. The device has the beneficial effects that the desiccant storage box and the pressure release component are integrated; the desiccant storage box is installed inside an explosion-proof component, so that the installation and the disassembly are inconvenient; the explosion-proof membrane is provided with the protective hood in the explosion-proof component, and a protective hood cover plate is installed at the outer side of the opening position of the protective hood, so that when the explosion-proof membrane bursts, explosion-proof membrane fragments fall into the equipment to play a role in protecting the site maintenance and the personal safety of operators.
Description
Technical field
The utility model belongs to the high-tension electricity technical field, is the device that is applied to integrate in the Cubicle Gas-Insulated Switchgear drier case and pressure release component specifically.
Background technology
In existing insulated metal sealing switch equipment, in order to adsorb the moisture in the insulating gas in the switchgear, guarantee the gas-insulated performance, in the air chamber of switchgear, lay the drier case usually, installation and removal are very inconvenient.In addition, in the explosion-proof member of prior art rupture pressure disc is not provided with protector, during the rupture pressure disc explosion, broken rupture pressure disc is with the ejection of gases at high pressure diversity, and the staff of execute-in-place and maintenance is damaged easily.
Summary of the invention
The utility model technical problem to be solved is, overcomes the weak point of prior art, and a kind of device that integrates drier case and pressure release component that is applied to Cubicle Gas-Insulated Switchgear is provided.
The technical scheme that the utility model adopts comprises pressure release component and flange, is processed with flange sealing trough in the flange bottom, and the flange seal circle is housed therein; Said pressure release component comprises the rupture pressure disc holding frame; Clamping rupture pressure disc in the rupture pressure disc holding frame is processed with the holding frame seal groove in rupture pressure disc holding frame bottom, and the holding frame sealing ring is installed therein; Said flange is processed with the notch cuttype inner chamber along axis direction, in the notch cuttype inner chamber of flange, the drier case is installed.
Said rupture pressure disc holding frame upper end is equipped with protective cover, and protective cover is at a side lateral opening, and in the opening part outside of protective cover the protective cover cover plate is installed.
Compared with prior art, the beneficial effect of the utility model is that the collection drier is deposited and pressure is released to one, and the drier case of depositing drier is installed in explosion-proof component inside; Installation and removal are convenient; In addition, in the explosion-proof member rupture pressure disc is provided with protective cover, and protective cover is at a side lateral opening; And the protective cover cover plate is installed in the opening part of the protective cover outside; The rupture pressure disc fragment falls in the equipment when making the rupture pressure disc explosion, can prevent the field personnel is damaged, and plays the effect of the maintenance that keeps the scene intact, operator's personal safety.
