Abstract
An anti-lightning strike acceleration transducer, comprises the acceleration transducer being located on tested aerogenerator measuring point, between acceleration transducer and tested aerogenerator, is provided with insulation spacer; When thunder and lightning hits after aerogenerator, the path that thunder energy is delivered on acceleration transducer by measuring point is insulated pad cut-out, and poly-edge pad plays the effect of insulation, have anti-lightning strike and good pressure-resistant performance, simple in structure, versatility is good, reliability is high, the feature of constructability.
Description
Technical field
The utility model belongs to acceleration transducer technical field, particularly a kind of anti-lightning strike acceleration transducer.
Background technology
The CMS system that current domestic vibration monitoring field is used, is used acceleration transducer to gather the Vibration Condition of each measuring point of aerogenerator.But because general acceleration transducer is not considered needs anti-lightning strike and withstand voltage under environment for use condition, easily cause after acceleration transducer is struck by lightning in operational process acceleration transducer to lose efficacy, affect the data acquisition of CMS system.
Summary of the invention
In order to overcome above-mentioned the deficiencies in the prior art, the purpose of this utility model has been to provide a kind of anti-lightning strike acceleration transducer, has anti-lightning strike and good pressure-resistant performance, simple in structure, and versatility is good, and reliability is high, the feature of constructability.
To achieve these goals, the technical solution adopted in the utility model is: a kind of anti-lightning strike acceleration transducer, comprise the acceleration transducer being located on tested aerogenerator measuring point, and between acceleration transducer and tested aerogenerator, be provided with insulation spacer.
Described insulation spacer upside is connected with acceleration transducer by upper metal flange screw, and bottom side is connected with tested aerogenerator measured point by lower metal flange screw.
Described insulation spacer upper and lower surface is equipped with subsider, and metal flange screw, lower metal flange screw are located in the subsider of insulation spacer upper and lower surface by bonding mode.
Described upper metal flange screw, the ring flange of lower metal flange screw are provided with monkey wrench clamping face.
Described insulation spacer adopts stupalith, and its both sides are provided with spanner clamping plane.
Described upper metal flange screw, lower metal flange screw adopt stainless steel.
The degree of depth of described subsider is 1.8mm.
The utlity model has following advantage:
1) structure of employing intermediate insulation; this is the design feature of this insulation spacer; make aerogenerator after being struck by lightning by the insulating effect of pad, thunderbolt energy can not be delivered on acceleration transducer, effectively protects acceleration transducer and a whole set of CMS system.
2) insulating trip uses high-strength ceramic, can effectively ensure stability and the permanance of insulating property, and the HFS of vibration also can effectively be delivered on acceleration transducer simultaneously.
3) between insulating trip and metal flange screw, use high rigidity, high-intensity glue carries out bondingly can ensureing that sensor adapts to higher mounting torque.
4) adopted the thread standard of industry universal, made insulation spacer there is very strong versatility, acceleration transducer that can adaptive multiple producers different model.Original scheme technological transformation can seamlessly transit, and does not need to increase extra utility appliance and can reach the effect of sensor lightning-protection.
5) insulating trip both sides are designed with M16 spanner clamping plane, facilitate site operation, use original torque spanner just can installation.
6) metal flange screw both sides are designed with the plane that can be clamped by monkey wrench, when insulation spacer suffering external force strong clash into or can use when metal flange screw and insulating trip are come off the super scope of sensor torsion monkey wrench to clamp this be held plane metal flange screw disassembled very easily from aerogenerator or acceleration transducer.
Brief description of the drawings
Accompanying drawing is the utility model structural representation.
Embodiment
Below in conjunction with accompanying drawing, structural principle of the present utility model and principle of work are described in further detail.
Referring to Fig. 1, a kind of anti-lightning strike acceleration transducer, comprises the acceleration transducer 1 being located on tested aerogenerator measuring point, between acceleration transducer 1 and tested aerogenerator, is provided with insulation spacer 4.

Described metal flange screw 2, lower metal flange screw 5 are located at by bonding mode in the subsider of insulation spacer 4 upper and lower surfaces, adopt high strength when bonding, and high rigidity bonding agent 3 carries out bonding.
Described upper metal flange screw 2, the ring flange of lower metal flange screw 5 are provided with monkey wrench clamping face.
Described insulation spacer adopts stupalith, and its both sides are provided with spanner clamping plane.
Described upper metal flange screw 2, lower metal flange screw 5 adopt stainless steel.
The degree of depth of described subsider is 1.8mm.
Upper metal flange screw 2 is installed double-screw bolt with the coupling part of acceleration transducer with M6.
Lower metal flange screw 5 is installed double-screw bolt with tested equipment measuring point coupling part with M6.
Described insulating trip is installed metal flange screw plane lower than potsherd surface 1.8mm, and insulating trip both sides have the plane that can be clamped by M16 spanner.
Lower metal flange screw 5 is M6 metal flange screw 5, upper metal flange screw 2 uses high strength with lower metal flange screw 5, the bonding agent of high rigidity is bonded on insulation spacer 4, upper metal flange screw 2 is for connecting the installation screw on acceleration transducer 1, metal flange screw 5 is for connecting the M6 threaded hole of measuring point on aerogenerator, and the lower sink structure on insulation spacer 4 two sides is for metal flange screw from radially spacing 2 and lower metal flange screw 5.
Principle of work of the present utility model is:
When thunder and lightning hits after aerogenerator, the path that thunder energy is delivered on acceleration transducer by measuring point is insulated pad cut-out, and poly-edge pad 4 plays the effect of insulation.
