Abstract
The utility model relates to the technical field of power monitoring equipment, in particular to a partial discharge on-line monitoring device for a switch cabinet. The monitoring device comprises a barrel-shaped aluminum casing, a partition board is arranged in the aluminum casing, a crystal liquid circuit board and a central processing unit (CPU) circuit board which are connected through an insertion needle and an insertion bar are fixedly arranged in the inner cavity of the aluminum casing over the partition board, a shielding housing is embedded into an outer cavity of the aluminum casing under the partition board, an ultrasonic circuit board and an ultrasonic signal collector are installed in the shielding housing, an ultrasonic oscillator is arranged in the ultrasonic signal collector, and annular magnets are respectively arranged at ports of the aluminum housing. The partial discharge on-line monitoring device for the switch cabinet has the advantages of convenient installation and operation, uninterrupted high-precision online monitoring, simple structure, low cost, and stable and reliable performance.
Description
Technical field
The utility model relates to a kind of electric power monitoring equipment technical field, especially relates to a kind of switch cubicle local discharge on-line monitoring device.
Background technology
Mostly be greatly relevant for switch cubicle partial discharge monitoring equipment at home at present and patrol and examine series products, this series products price height, complicated operation, operative technique level to the related personnel requires than higher, and the monitoring right and wrong that this series products is implemented are successional, can not in time find the inner potential safety hazard that occurs of switch cubicle.This series products that at present has some can implement continuous monitoring abroad, but complex structure is expensive, is not adapted at domesticly applying on a large scale.
Summary of the invention
The purpose of this utility model is to avoid prior art complex structure, defective that cost is high that a kind of switch cubicle local discharge on-line monitoring device is provided, thereby effectively solves the defective that exists in the prior art.
For achieving the above object, the technical scheme that the utility model is taked is: described a kind of partial discharge of switchgear on-Line Monitor Device, be characterized in comprising aluminum hull, be provided with dividing plate in aluminum hull, be fixedly installed the liquid crystal circuit board and the cpu pcb that are connected by the contact pin insert row in the aluminum hull inner chamber on dividing plate top, be equipped with shielding case in the aluminum hull exocoel of the lower partition, ultrasonic circuit board and ultrasonic signal collector are installed in shielding case, be provided with ultrasonic vibrator in the ultrasonic signal collector, the port of aluminum hull is provided with annular magnet
Described aluminum hull is barrel-like structure.
Described dividing plate is arranged on the aluminum hull by draw-in groove.
Described ring-shaped magnet is installed in the end of aluminum hull by iron grooved ring.
The outer wall of described grooved ring links to each other by screw thread with the port inner wall of aluminum hull.
The beneficial effects of the utility model are: described a kind of switch cubicle local discharge on-line monitoring device, the signal receiver of its sensor front end can be concentrated interior ultrasonic signal in the ultrasonic vibrator that collects the sensor middle part on a large scale, thereby enlarge the sensing range of sensor, and strengthen the ultrasonic signal that the shelf depreciation that collects produces.Its installation and simple operation, can carry out the continuously remarkable advantage of uninterrupted high precision on-line monitoring, simultaneously, it is simple in structure, and is cheap, and properties of product are reliable and stable.
