Description
Technical field
The present invention relates to a kind of detection devices, and in particular to a kind of vibration of GIS isolation switch contact and displacement detector.
Background technique
Gas insulated combined electrical equipment (Gas Insulated Switchgear, GIS) is since occupied area is small, maintenance work
Measure small reason in power grid using more and more extensive.
It is at present to pay close attention to its state of insulation for GIS more, its state of insulation is detected using shelf depreciation and has been carried out
A large amount of research.But mechanical body GIS complicated as one, machine performance are also the important side for being related to its safe operation
Face.Inside GIS, disconnecting switch is prone to wear out due to frequent operation at contact, additionally due to herein current-carrying face occur it is prominent
Become, generate current constriction, contact displacement can be generated under the action of loop current, and then guide rod is driven to generate vibration signal.
Vibration signal is transmitted to GIS shell by insulator so as to be detected from shell.Using being arranged in outside GIS
The vibrating sensor of shell carries out the detection of GIS isolation switch contact state, the field application obtained at present.
But what is obtained due to vibrating sensor measurement is indirect signal, and how at present also the relationship between contact displacement
It is difficult to obtain, and characterizes a key of contact state when the vibration signal characteristics of shell.
Therefore study one kind can precise measurement contact displacement, it is compared with GIS case vibration signal, to obtain
The corresponding relationship of GIS case vibration and isolation switch contact displacement state is obtained, it is outstanding for isolation switch contact contact state test
It is important.
Summary of the invention
To solve the deficiencies in the prior art, the purpose of the present invention is to provide a kind of vibration of GIS isolation switch contact and positions
The detection device of shifting state.
In order to achieve the above objectives, the present invention adopts the following technical scheme that：
A kind of vibration of GIS isolation switch contact and displacement detector, the both ends of GIS guide rod pass through disconnecting switch in shell
It is connected, GIS guide rod is fixed by insulator and shell；It is arranged outside the vibrating sensor patch shell being connected with oscillograph；
One end of spring abuts disconnecting switch, another termination displacement indicator, the displacement shown by displacement indicator
The displacement of intuitive observation contact；
Current lifting device is the power supply of GIS guide rod, carries out the application of current signal.
Above-mentioned shell is " returning " shell body.
Above-mentioned disconnecting switch includes matched static contact and moving contact, and spring abuts static contact.
Above-mentioned current lifting device is socketed on outside shell.
Above-mentioned insulator is disc insulator, is fixed by insulated bolt and shell, and shell is avoided to form electric current.
Above-mentioned spring is precision spring.
The invention has the beneficial effects that：
A kind of GIS isolation switch contact vibration of the invention and displacement detector, provide electric current by current lifting device；Pass through
The fixed GIS guide rod of disc insulator and shell, further avoid shell from getting an electric shock by insulated bolt；It is detected by vibrating sensor
Because being vibrated caused by disconnecting switch movement, and by oscilloscope display；The displacement of static contact is detected by precision spring, and by being displaced
Indicator intuitively measures the displacement of contact.
A kind of GIS isolation switch contact vibration of the invention and displacement detector, pass through measure vibrating sensor
Vibration signal compares, and realizes the accurate measurement of GIS isolation switch contact vibration and displacement state, for studying disconnecting switch
Frequent operation, after leading to contact abrasion, because current constriction cause contact be displaced situation, have it is more clear clearly recognize,
Have convenient for the later period and targetedly makes improvements very much.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of a kind of GIS isolation switch contact vibration and displacement detector of the invention.
Attached meaning marked in the figure is as follows：1, shell, 2, GIS guide rod, 3, current lifting device, 4, insulator, 5, disconnecting switch,
6, precision spring, 7, displacement indicator, 8, vibrating sensor, 9, oscillograph.
Specific embodiment
Specific introduce is made to the present invention below in conjunction with the drawings and specific embodiments.
A kind of vibration of 5 contact of GIS disconnecting switch and displacement detector, including " returning " shell body 1, and be placed in shell 1
GIS guide rod 2；The both ends of GIS guide rod 2 are connected by disconnecting switch 5, and disconnecting switch 5 includes matched static contact and moving contact
(static contact clamping moving contact)；One end of precision spring 6 abuts static contact, the other end draw shell 1 and with 7 phase of displacement indicator
Even.
GIS guide rod 2 is fixed by disc insulator 4 and shell 1, and insulator 4 is fixed by insulated bolt and shell 1；
Shell 1 is externally provided with the vibrating sensor 8 being connected with oscillograph 9.
The current lifting device 3 outside shell 1 is socketed on as the power supply of GIS guide rod 2, carries out the application of current signal.
In actual tests, according to the needs of test, each parameter can be adjusted flexibly, such as：3 parameter of current lifting device can be according to need
It is chosen, position of vibrating sensor 8 etc. can be chosen as needed.
When external loop applies current signal, since contact and current constriction act on, contact can be generated at contact
Displacement, drives spring to generate displacement at this time, and amount of displacement and direction can be carried out real-time display, then can passed through by position indicator
The displacement of precision spring 6 obtains the displacement of contact.
Contact displacement linkage GIS guide rod 2 vibrates, and by the linkage shell 1 of insulator 4, should by the detection of vibrating sensor 8
Vibration, oscillograph 9 measure the vibration signal that vibrating sensor 8 is fed back, it are compared with the displacement of precision spring 6, then
It can get the relationship between the actual displacement and case vibration signal of contact, and then accurately obtain the state of contact.
The basic principles, main features and advantages of the invention have been shown and described above.The technical staff of the industry should
Understand, the above embodiments do not limit the invention in any form, all obtained by the way of equivalent substitution or equivalent transformation
Technical solution is fallen within the scope of protection of the present invention.
