Description
Technical field
The present invention relates to power measurement field, more particularly, it relates to a kind of Substation Insulator wireless live crack detector.
Background technology
Porcelain strut insulator is the important composition equipment of power plant and substation operation, is used in a large number in power system,
There is the three zones such as support wire, chopper and high-voltage switch gear.Once porcelain strut insulator cracks or ruptures, Ke Nengyin
Send out large area short circuit, ground connection, even cause the injures and deaths of neighbouring staff.Caused by the mechanical damage of porcelain strut insulator
The incidence rate of chopper and high-voltage switch gear fault is the highest, particularly aging along with insulator, and their fault occurs
Rate increases more therewith.The fault of many electric power enterprises and transformer station practice have shown that, prevent this type of accident it is crucial that at porcelain pillar
In insulator running, detect they defects such as the most various crackles and mechanical strength reduction in advance, according to specifically
Situation takes corresponding remedial measure, thus avoids the generation of accident.Therefore a height with live detection insulator function
Effect crack detector is equipment necessary to power system.
Porcelain pillar insulator electrified automatic tester uses unique vibroacoustics method, by the bottom of porcelain strut insulator
Portion launches special incentive vibration wave, and receives vibratory response, is stored as data, and obtains wave spectrogram with software analysis.Wireless biography
Defeated transmission means has multiple, and such as bluetooth is the most convenient.No matter use which kind of mode, be intended to use antenna and launch and pass
Defeated.
The deficiency of the insulator crack detector of prior art is: housing is all-metal construction, if Antenna Design is bad, then imitates
Rate can be greatly affected.According to the requirement of on-the-spot test, be wirelessly transferred need to reach 10 meters the most farther.
Summary of the invention
It is an object of the invention to overcome the deficiencies in the prior art, it is provided that transformer station's insulation that a kind of radio transmission efficiency is high
Sub-wireless live crack detector.
Technical scheme is as follows:
A kind of Substation Insulator wireless live crack detector, including metal shell, probe, antenna extends to metal shell
Panel front end, metal shell does not forms signal shielding to antenna.
As preferably, metal shell offers opening in the position near panel.
As preferably, on the circuit board in metal shell, antenna is connected to the front edge of circuit board.
As preferably, circuit board being additionally provided with LED module, key-press module, antenna is arranged on LED module and key-press module
Middle.
As preferably, key-press module press key lever by bonded insulation, insulation extends to outside metal shell by key lever, insulation
The distance of module distance board edge is more than the distance of antenna distance board edge.
As preferably, the LED of LED module extends to the panel front end of metal shell, concordant with antenna, antenna and LED
The distance of module is more than the distance of antenna with key-press module.
Beneficial effects of the present invention is as follows:
Substation Insulator wireless live crack detector of the present invention, antenna is arranged on the front end of PCB, reaches face as far as possible
Front edge of board, avoids the signal shielding of metal shell.Antenna is arranged in the middle of LED module and key-press module, avoids metal electron
The interference of components and parts.Except antenna is in addition to the position of PCB needs design, and the opening at the panel of metal shell also has exquisite,
Concede the space that antenna carries out launching and receiving.
Through actual measurement, the present invention is under wifi environment, and transmission range has reached 16 meters, and in 6 meters, retransmission probability is less than 8%, full
The requirement that foot uses.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention；
Fig. 2 is the partial schematic diagram (in order to illustrate antenna, LED module, key-press module) of circuit board；
In figure: 10 is metal shell, 11 is opening, and 12 is panel, and 13 is probe, and 20 is circuit board, and 21 is antenna, and 22 are
LED module, 23 is LED, and 24 is key-press module, and 25 is by key lever.
Detailed description of the invention
Below in conjunction with drawings and Examples, the present invention is described in further detail.
The present invention is to solve in prior art, antenna transmits inefficient problem on metal shell, it is provided that a kind of
Substation Insulator wireless live crack detector, as it is shown in figure 1, include metal shell 10, probe 13, antenna 21 extends to metal-back
Panel 12 front end of body 10, metal shell 10 does not forms signal shielding to antenna 21.
In order to concede the space that antenna 21 carries out launching and receiving, metal shell 10 offers in the position near panel 12
Opening 11.
As in figure 2 it is shown, on circuit board 20 in metal shell 10, antenna 21 is connected to the front edge of circuit board 20, with
Just antenna 21 can preferably extend to panel 12 front end, it is to avoid the signal shielding of metal shell 10.
LED module 22, key-press module 24 it is additionally provided with, if but antenna 21 is provided around LED 23 on circuit board 20
And button, and all LED 23 and button are metal, can have an impact the performance of antenna 21.Therefore, antenna 21 is arranged on LED
Module 22 is middle with key-press module 24, to avoid the interference of metal electron components and parts.
In the present invention, key-press module 24 press key lever 25 by bonded insulation, insulation extends to metal shell by key lever 25
Outside 10, the key-press module 24 distance apart from circuit board 20 edge is more than the antenna 21 distance apart from circuit board 20 edge.LED module
The LED 23 of 22 extends to panel 12 front end of metal shell 10, concordant with antenna 21；Then in order to be further ensured that antenna 21
Efficiency of transmission, the distance of antenna 21 and LED module 22 is more than the distance of antenna 21 with key-press module 24.
Through actual measurement, the present invention is under wifi environment, and transmission range has reached 16 meters, and in 6 meters, retransmission probability is less than 8%, full
The requirement that foot uses.
Above-described embodiment is intended merely to the present invention is described, and is not used as limitation of the invention.As long as according to this
Bright technical spirit, be changed above-described embodiment, modification etc. all will fall in the range of the claim of the present invention.
