Description
Technical field
The utility model relates to sensor technical field, more particularly, relates to a kind of anti-lightning strike sensor comprising sensor outer housing, Sensor core unit and connector.
Background technology
Sensor application field is extensive, and installation environment is complicated.Requiring that in the application that reliability is high, space enrironment is severe, sensor needs to have self-protection, resisting the ability of surge thunderbolt.
Traditional anti-lightning strike sensor protection mode between earth point and sensor connect lines, is incorporated to gas-discharge tube, pressure-active element or TVS homenergic to release device, to protect sensor circuit injury-free.But when sensor fixing body cannot effective grounding time, thunderbolt energy bleed-off circuit is obstructed, and protective capability obviously declines.In high-tension electricity transmission tower, skyscraper, bridge, on the facilities such as aerogenerator, traditional anti-lightning strike protected effect all obviously declines.
Summary of the invention
The utility model solves the problem and adopts the method for insulation isolation, thunderbolt energy is released by means of only sensor outer housing, cannot import sensor degradation circuit, when shell cannot effective grounding, keep anti-lightning effect.
It is as described below that the utility model solves the technical scheme that its technical matters adopts: a kind of anti-lightning strike sensor, comprise sensor outer housing, Sensor core unit and connector, connector comprises connector housing and is fixed on the contact pin in connector housing through seal, it is characterized in that, anti-lightning strike sensor also comprises insulation protective jacket, described connector is reinforced insulation type connector, insulation protection is sheathed in described sensor outer housing, described Sensor core unit to be located in insulation protective jacket and to be wrapped up completely through insulation protective jacket, the through hole that described Sensor core unit is provided with through insulation protective jacket upper end is connected with the contact pin in connector housing.
According to said structure, wherein said insulation protective jacket material is the one or more combination in pottery, glass and plastics.
According to said structure, wherein said insulation protective jacket is formed in one structure or form for multiple sections fit.
According to said structure, in wherein said insulation protective jacket, be provided with insulating trip.
According to said structure, wherein said connector inwall is provided with the first dead ring.
According to said structure, wherein said connector lower end is provided with the second dead ring.
According to said structure, as preferably, further, described insulation protective jacket thickness is 0.1-5 millimeter.
According to said structure, as preferably, further, the diameter of the through hole that described insulation protection puts is 0.2-5 millimeter.
According to said structure, wherein said seal material is glass or pottery.
According to the utility model of said structure, its beneficial effect is, isolated insulation between the utility model shell and Sensor core unit, senses that the high electric field pulse on shell cannot invade Sensor core unit.Reinforced insulation type connector is not changing under connector dimensional conditions, adopts stereoscopic insulation body structure, improves the insulating capacity between connecting needle and shell.
The utility model, when not changing sensor bulk, significantly improves the insulating capacity between shell and core sensor unit.When assembly cannot provide effective grounding (as high-altitude is installed), the utility model available protecting sensor itself does not damage in thunderbolt.

Reinforced insulation type connector 4 is positioned at anti-lightning strike sensors topside, is fixed together, as shown in Figure 3 with sensor outer housing 1.The first dead ring 4.3 that reinforced insulation type connector comprises connector housing 4.1, the contact pin 4.2 be fixed on through glass or ceramic material seal 4.4 in connector housing, connector inwall are provided with and connector lower end are provided with the second dead ring 4.5.First dead ring 4.3 and the second dead ring 4.5 are for increasing the creepage distance between contact pin and connector.The height of the first dead ring 4.3 and the second dead ring 4.5 is according to lightning protection level adjustment, and differing heights dead ring is the utility model protection domain.
Sensor core unit 3 to be located in insulation protective jacket 2 and to be wrapped up completely through insulation protective jacket 2, and the through hole (can pass connecting line) that Sensor core unit 3 is provided with through insulation protective jacket 2 upper end is connected with the contact pin 4.2 in connector housing.
Insulation protective jacket 2 is made up of high pressure resistant insulation material, and concrete material is chosen as the one or more combination in pottery, glass and plastics.Insulation protective jacket 2 is formed in one structure or form for multiple sections fit.Assembling mode can be bonding, riveted joint, sintering or screw thread socket.
Insulation protective jacket 2 thickness is 0.1-5 millimeter.The diameter of the through hole on insulation protective jacket 2 is 0.2-5 millimeter.
Above-mentionedly to illustrate for the utility model, be not limited to the utility model.
