Abstract
The utility model provides a contact net dynamic feature test device based on system response test, which comprises a pantograph and a laser distance testing sensor equipment arranged below the sliding plate and composed of a support, a supporting plate, and a laser distance testing sensor. The advantage of the utility model is that the product does not change the original pantograph structure, and not provide any sensor on the pantograph, and not change the feature of pantograph to make the test results closer to the actual condition. In addition, the utility model belongs to non-contact testing and is separated from the high-voltage end, thus being not subject to the impact of the magnetic disturbance of the electric arc formed by offline pantograph and making the resolution and precision of test signals higher. The utility model is mainly used to the real test of dynamic feature parameters of high-speed electric railway contact grid.
Description
Technical field
The utility model relates to a kind of dynamic characteristic parameter proving installation that contacts electrical network, particularly relates to a kind of contact net dynamic characteristic test device based on the system responses test.
Background technology
The dynamic characteristic parameter of applied to high-speed railway touching net is to estimate the important parameter that contact net is subjected to properties of flow, is the important evaluation index of catenary property.At present, extensively adopt the direct method of testing of bow net contact pressure both at home and abroad.A cantilevered pressure test sensor promptly is installed respectively on four angles of pantograph pan, is used to test the balance contact force.On central authorities' bow body of pantograph pan, an acceleration transducer is installed, is used to test the inertia contact force.The contact force sum of equilibrant is bow net contact general pressure, this kind method of testing is simple, calculate simple and direct, but when high-speed cruising, some potential safety hazard that has accident between pantograph, 1) at four jiaos and central sensor installation of pantograph pan, changes the pantograph contour structures, influenced pantograph whole rigidity, fragile slide plate, sensor has changed the pantograph aerodynamic performance simultaneously, can not truly reflect the bow net operating mode, makes the pantograph bad stability; 2) Fu Jia sensor has increased pantograph pan weight, and the dynamic following of pantograph is affected, and the inertial force that bow net impacts increases, fragile pantograph; 3) in the high-pressure side acquired signal, be subjected to the electromagnetic interference effect that electric arc that the bow net off-line forms brings easily, the resolution of test signal and precision are reduced.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned shortcoming, and a kind of pantograph structure that do not change is provided, and makes the resolution and the higher contact net dynamic characteristic test device based on the system responses test of precision of test signal.
The utility model comprises pantograph and laser range sensor equipment based on the contact net dynamic characteristic test device of system responses test.Wherein pantograph is arranged on the insulator on the installing plate by installing plate, is positioned at the base of insulator upper end, is installed in bow arm and bow-lifting device on the base, and the pantograph pan that is installed on the bow arm is formed; Laser range sensor equipment be installed in pantograph pan under, by support, rack-mount back up pad is arranged on laser range sensor evenly distributed side by side on the back up pad and forms, and makes its laser range sensor detection window aim at the pantograph pan bottom.During use installing plate and support are installed in the inspection vehicle top simultaneously.
The utility model based on the principle of work of the contact net dynamic characteristic test device of system responses test is, electric locomotive (electric motor car group) obtains electric energy by the sliding contact between pantograph and contact wire, for guaranteeing reliable contact the between pantograph and contact wire, have certain contact pressure between them, pantograph produces the dynamic response of transverse vibration.Pantograph pan produces distortion under the effect of contact pressure.Laser transmitter projects laser is to the pantograph pan bottom, measure the distance of pantograph pan bottom by the laser that returns to laser sensor, thereby measure the dynamic response of pantograph pan under the pressure effect of contact wire, and calculate bow net contact pressure, bow net off-line and bow net and go out acceleration.
The utility model is not change original pantograph structure based on the advantage of the contact net dynamic characteristic test device of system responses test, any sensor is not installed on pantograph yet, do not change the pantograph characteristic, make test result more near the bow net actual conditions, and belong to non-contact detection, carry out light with high-pressure side and isolate, the influence of the electromagnetic interference (EMI) that the electric arc that not formed by the bow net off-line brings makes the resolution of test signal and precision higher.Be mainly used in the dynamic characteristic parameter of real-time testing high-speed electric railway contact electrical network.
