Technical field
The present invention relates to a kind of vibration detection devices, and in particular to the vibration detection dress of GIS under a kind of dry run operating condition It sets.
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, utilize shelf depreciation Detection is carried out to its state of insulation, a large amount of research has been carried out.
But mechanical body GIS complicated as one, machine performance are also the importance for being related to its safe operation.? There are disconnecting switch, breaker etc., there are the equipment of contact inside GIS, in the junction of contact since connecting rod size becomes Change, electric current is shunk here, and vibration can be generated at contact, and vibration is transmitted to shell by components such as insulators, is produced in shell Raw detectable vibration signal.Application has been obtained at present using the measurement that vibration signal carries out GIS machine performance.
It is the single current signal of application without applying voltage signal but at present under study for action in order to simple and convenient, and Be in the actual operational process of GIS voltage and current signals and meanwhile act on, therefore study one kind can apply simultaneously voltage and The experimental provision of current signal is very necessary.
In addition, actual isolation switch contact is mostly used in current research, since the contact condition of practical contact is difficult to Control, can not carry out careful research, thus study it is a kind of can characterize due to guide rod it is discontinuous caused by current constriction Test parts can then carry out more targeted research.
Summary of the invention
To solve the deficiencies in the prior art, the purpose of the present invention is to provide GIS under a kind of analog actual condition to vibrate The detection device of characteristic.
In order to achieve the above objectives, the present invention adopts the following technical scheme that:
The vibration detection device of GIS under a kind of dry run operating condition, the both ends of GIS guide rod are connected by connecting rod in shell, GIS guide rod is fixed by insulator and shell;It is arranged outside the vibrating sensor patch shell being connected with oscillograph;

The vibration detection device of GIS, is mentioned by gas-insulated testing transformer under a kind of dry run operating condition of the invention Voltage supplied signal, current lifting device provide current signal, and two kinds of signals apply Simulated GlS actual operating mode simultaneously;By thickness and The adjustable connecting rod of length is connected with GIS guide rod, and simulating disconnecting switch, contact of breaker etc. in practical GIS, there are conductor sizes The component of mutation;By the voltage and current signals applied simultaneously, current constriction is generated in guide rod discontinuous segment, and then produce Raw vibration signal, the measurement of vibration signal is carried out using vibrating sensor, studies the vibration characteristics of GIS under actual condition.
The vibration detection device of GIS under a kind of dry run operating condition of the invention, structure is simple, easy to detect, operating condition Simulation is accurate, can detect a variety of vibration characteristics generated by current constriction, has very strong practicability and wide applicability.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the vibration detection device of GIS under a kind of dry run operating condition of the invention.
Attached meaning marked in the figure is as follows: 1, shell, 2, GIS guide rod, 3, transformer, 4, current lifting device, 5, connecting rod, 6, vibration Dynamic sensor, 7, oscillograph, 8, insulator.
Specific embodiment
Specific introduce is made to the present invention below in conjunction with the drawings and specific embodiments.
The vibration detection device of GIS under a kind of dry run operating condition, 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 connecting rod 5.GIS guide rod 2 is fixed by disc insulator 4 and shell 1, and absolutely Edge 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.
SF6Gas-insulated power frequency testing transformer and GIS guide rod 2 share a metal shell, High voltage output directly with height Guide rod is pressed to be connected.
Connecting rod replaces one section of guide rod, the variation to the conductor size at Simulated GlS contact.
In actual GIS, the positions such as disconnecting switch, contact of breaker can have the discontinuous of conductor size, this to lead The position that body size mutates can generate vibration due to current constriction.It can be true with one section of thickness and the adjustable connecting rod of length It is real to simulate such situation, the simulation of different degrees of current constriction is realized by the thickness and length that adjust connecting rod.
When detection:
Gas-insulated testing transformer 3 generates voltage signal, and current lifting device generates current signal, and two kinds of signals apply mould simultaneously Quasi- GIS actual operating mode, the operating condition that the ratio of two kinds of signals can refer to practical GIS are chosen.
Current constriction degree can be adjusted by the length and thickness of adjusting rod, simulate the vibration under different current constriction degree Emotionally condition.
It recycles vibrating sensor to carry out the measurement of vibration signal, is believed by the detection that oscilloscope display vibrating sensor is fed back Number, and then study the GIS vibration signal in the case of different current constrictions.
In test, according to the needs of test, each parameter can be adjusted flexibly, such as: transformer and current lifting device parameter can roots According to being chosen, the position of vibrating sensor, the thickness of connecting rod and length are chosen etc..
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.
