Description
Technical field
The utility model relates to Partial Discharge Detection field, particularly relates to a kind of local discharge detection device.
Background technology
Shelf depreciation refers to the electric discharge that Electric Power Equipment Insulation layer occurs in subrange under enough strong electric field action.The measurement data of Partial Discharge Detection equipment is as the important indicator judging power equipment operating condition, its correctness directly affects the correct judgement to power equipment operating condition, existing Partial Discharge Detection equipment just gathers local discharge signal, output characteristic amount is equivalent, the accuracy of measurement own to oneself can only rely on external calibrator to calibrate, and the accuracy of detection of existing partial-discharge measuring device is lower.
Summary of the invention
In order to solve the problem that in prior art, the accuracy of detection of partial-discharge measuring device is lower, the utility model provides local discharge detection device, reaches the object of high-acruracy survey.
The utility model adopts following scheme technically:
A kind of partial-discharge measuring device, comprise collection casing, comprise local discharge signal collecting unit, sensor and data storage cell, described local discharge signal collecting unit and sensor are arranged on and gather in casing, described data storage cell is connected with described collection casing, and described local discharge signal collecting unit is connected with described sensor.
As further improvement of the utility model: described sensor includes but not limited to high frequency sensors, superfrequency sensor and ultrasonic sensor.
As further improvement of the utility model: described partial-discharge measuring device also comprises noise reduction module; Described noise reduction module connects described local discharge signal collecting unit.
As further improvement of the utility model: described data storage cell also comprises display unit, described display unit is wired, wireless output module or display screen.
As further improvement of the utility model: described data storage cell is connected by USB serial ports with described collection casing.
As further improvement of the utility model: described data storage cell is connected by wireless network with described collection casing.
As further improvement of the utility model: gather the metal cabinet that casing is sealing.
The beneficial effects of the utility model are embodied in: improve greatly each the data precision measured, and avoid being forbidden causing trouble to be reported by mistake due to measurement data or fault such as not to report at the problem, thus ensure the reliable power supply of industry or resident.
Accompanying drawing illustrates:
Fig. 1 is the system chart of the utility model partial-discharge measuring device.
Embodiment:
By reference to the accompanying drawings, embodiment of the present utility model is further described:
A kind of partial-discharge measuring device, comprise and gather casing, local discharge signal collecting unit, sensor and data storage cell, described local discharge signal collecting unit and sensor are arranged on and gather in casing, described data storage cell is connected with described collection casing, and described local discharge signal collecting unit is connected with described sensor.
Described sensor includes but not limited to high frequency sensors, superfrequency sensor and ultrasonic sensor.
Described partial-discharge measuring device also comprises noise reduction module; Described noise reduction module connects described local discharge signal collecting unit.
Described data storage cell also comprises display unit, and described display unit is wired, wireless output module or display screen.
Described data storage cell is connected by USB serial ports with described collection casing.

Described collection casing is the metal cabinet of sealing.
Described high frequency sensors is arranged on the ground wire of described power equipment.
Described superfrequency sensor setting is on the predeterminated position being reference point with described power equipment.
Described ultrasonic sensor is arranged in the metal outer wall of described power equipment.
In one embodiment, described local discharge signal collecting unit is provided with multiple acquisition channel, each acquisition channel is connected respectively a sensor, as the first acquisition channel is connected with high frequency sensors, for receiving the high-frequency signal of the expression local discharge signal from high frequency sensors, second acquisition channel is connected with superfrequency sensor, for receiving the ultrahigh-frequency signal of the expression local discharge signal from superfrequency sensor, 3rd acquisition channel is connected with ultrasonic sensor, for receiving the ultrasonic signal of the expression local discharge signal from ultrasonic sensor.All be connected with the 3rd acquisition channel with the first acquisition channel, the second acquisition channel by data storage cell, for controlling the sampling pattern of the first acquisition channel, the second acquisition channel and the 3rd acquisition channel, the data collected are transferred to data storage cell process, and the data collected directly are transferred to display unit display.And display unit can be the output module of wire and wireless, it also can be display screen.In one embodiment, high frequency sensors is arranged on the ground wire of power equipment, and superfrequency sensor setting is on the predeterminated position taking power equipment as reference point, and ultrasonic sensor is arranged in the metal outer wall of described power equipment.
In another embodiment, local discharge signal collecting unit is for receiving the shelf depreciation electric signal of calibrating signal or sensor output and its denoising, amplification being processed and be converted to digital signal and export to data analysis unit.Data storage cell: the Standard Eigenvalue that the characteristic quantity obtained after processing the calibration data received (calibrating signal puts through office the data exported after collecting unit process) is corresponding with calibrating signal contrasts, and comparing result is exported to data storage cell show.
Above content is in conjunction with concrete preferred implementation further description made for the present invention, can not assert that specific embodiment of the invention is confined to these explanations.Concerning general technical staff of the technical field of the invention, without departing from the inventive concept of the premise, the some simple deduction or replace done, all should be regarded as belonging to protection scope of the present invention.
