Abstract
The utility model discloses a device structure assisting in searching single-phase grounding faults. The device comprises a cabinet body, a cabinet door and a high-voltage component and is characterized in that the cabinet body is composed of a rain-proof roof, a mounting plate, a door plate, a bottom plate and two side plates, the high-voltage component is composed of composite wall-through bushings, high-voltage vacuum alternating-current contactors and high-voltage resistors, the mounting plate is provided with mounting holes and is used for fixing the high-voltage vacuum alternating-current contactors, the high-voltage component is arranged in the middle part of the cabinet body, the composite wall-through bushings pass through the rain-proof roof and the upper top of the cabinet body and extend into the cabinet body, and the high-voltage resistors are uniformly distributed at the bottom of the cabinet body in a rectangular array. The device structure can be used to automatically identify a fault when a circuit is subject to a single-phase grounding fault and can be started according to a mode set by a program, generate characteristic current on the circuit and cooperate with a fault indicator to carry out fault location. The device structure assisting in searching single-phase grounding faults can be used in humid and high-altitude outdoor areas.
Description
Technical field
The utility model relates to a kind of distribution automation equipment, and more specifically, the utility model relates to the apparatus structure that singlephase earth fault is searched in a kind of help.
Background technology
Along with the great development of national development of the West Regions and national Western Energy Resources economy, the distribution automation equipment that adapts to high altitude environment also becomes present part market bid target.China has a vast territory, and in the world distinctive vast high altitude localities is arranged, and must have a large amount of distribution automation coordinative composition of equipments to use, and stands this type of harsh physical environment and all can cause and seriously influence, and makes can not bring into normal play function or shorten serviceable life of product.Therefore, all must re-start research and development design, experimental study to the product of high height above sea level, set about from the design of product, take into full account high altitude environment to the impact of equipment performance.
The utility model content
In order to overcome defects, the utility model provides a kind of help to search the apparatus structure of singlephase earth fault, comprise cabinet, the cabinet door, high voltage device, it is characterized in that: cabinet is by rainproof top, installing plate, door-plate, base plate and biside plate consist of, high voltage device is by compound wall bushing, high voltage vacuum AC contactor, high-tension resistive consists of, installing plate is provided with mounting hole, is used for fixedly high voltage vacuum AC contactor, and this element is arranged at the cabinet middle part, compound wall bushing passes to push up on rainproof top and the cabinet and stretches in the cabinet, high-tension resistive is arranged at bottom of cabinet bulk, and rectangular array is evenly arranged, and makes its radiating effect better.
The utility model can be identified fault automatically when circuit generation singlephase earth fault, and the mode that follow procedure is set starts, and produces on the line characteristic current, cooperates fault detector to carry out localization of fault.The utility model can be in moist, the outdoor use in high altitude localities.
Description of drawings
Fig. 1 is the device exploded view that singlephase earth fault is searched in help of the present utility model;
Fig. 2 is the schematic diagram that the device interior layout of singlephase earth fault is searched in help of the present utility model.
Embodiment
Below in conjunction with specific embodiment the utility model is described in further detail:
Internal placement of the present utility model as shown in Figure 2,201 is compound wall bushing, 202 is the broadening formation entrance hole, 203 is high-pressure AC vacuum contactor, 204 is high-tension resistive, 205 is installing plate, 206 is epoxy plate, 207 is travel switch.Fig. 1 is scantling plan of the present invention, and compound wall bushing 201 passes to push up on rainproof top 102 and the cabinet and stretches into cabinet 103, and in order to strengthen the creepage distance that pushes up on compound wall bushing 201 and the cabinet, broadening formation entrance hole 202 is adopted on the top on the cabinet.High-pressure AC vacuum contactor 203 is arranged at cabinet 103 middle parts, high-tension resistive 204 is arranged at cabinet 103 bottoms, and rectangular array is evenly arranged, and makes heat radiation reach optimum efficiency, the side cabinet that is positioned at high-tension resistive 204 both sides is epoxy plate 206 fixedly, increases insulating property.Whole equipment adopts stainless steel material, and sprays outdoor powder, prevents that environmental factor is to the metal parts corrosion of equipment.
The utility model can be identified fault automatically when circuit generation singlephase earth fault, and the mode that follow procedure is set starts, and produces on the line characteristic current, cooperates fault detector to carry out localization of fault.The utility model can be in moist, the outdoor use in high altitude localities.
Above listed each embodiment enumerates of the present utility model, and those skilled in the art can understand the simple modification done, replacement or belong to protection domain of the present utility model with the combination of this area customary means on the utility model basis.
