Sublink, pressure pot are connect by pipeline with Buchholz relay, are surveyed capacitance device and are connected with Buchholz relay by pipeline, solenoid valve
It is arranged in and surveys on the pipeline between capacitance device and Buchholz relay；
The pressure gauge is quake-proof type pressure gauge；
The pressure pot is made of metal；
The device for exerting, survey capacitance device, control device are fixed on flat bogie.
The utility model has the following beneficial effects:
Device for exerting uses pressure pot, by applying pressure in pressure pot, is pressed by pipeline to Buchholz relay,
It is the oil in Buchholz relay under pressure by checking verification by volume oily in container in shut-off valve injection container
It is whether normal, the characteristics of having structure simple, facilitate operation, simplify the number of working processes.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Fig. 2 is the utility model circuit connection diagram.
Specific embodiment
As shown in Figs. 1-2, a kind of Buchholz relay on-site calibrator, including device for exerting, survey capacitance device and control device,
Device for exerting includes pressure pot 1 and pressure gauge 2, and pressure gauge 2 is arranged on pressure pot 1, and surveying capacitance device includes shut-off valve 4 and beaker
6, control device includes power supply, solenoid valve 5, buzzer and terminal, and 3 contact of power supply and Buchholz relay, buzzer connect to be formed
Circuit, the connection of solenoid valve 5 and terminal link, pressure pot 1 are connect by pipeline with Buchholz relay 3, survey capacitance device and gas after
Electric appliance 3 is connected by pipeline, and solenoid valve 5, which is arranged in, to be surveyed on the pipeline between capacitance device and Buchholz relay 3；Pressure gauge 2 is resistance to
Shake type pressure gauge；Pressure pot 1 is made of metal；Device for exerting, survey capacitance device, control device are fixed on flat bogie.
In use, the Buchholz relay of substation is removed, it is placed on the position of the Buchholz relay 3 of Fig. 1, by pressure pot
The pipeline of stretching accesses Buchholz relay, connects Buchholz relay from the terminal extraction wire of control device, AC power source is connect
Enter terminal, opens pressure pot burp valve and press to Buchholz relay, under pressure, oil passes through pipe in Buchholz relay
Road flows into beaker by solenoid valve, shut-off valve, when the contact of Buchholz relay is connected, electromagnetism valve events, while buzzer report
It is alert, power supply is closed, judges whether Buchholz relay meets the requirements by reading beaker inner fluid scale.
The device for exerting of the utility model use pressure pot, by applying pressure in pressure pot, by pipeline to watt
This relay pressure is that the oil in Buchholz relay is injected in container by shut-off valve under pressure, by oily in container
Volume check whether verification normal, have structure simple, facilitate operation, the characteristics of simplification the number of working processes.
The above is only the preferred embodiment of the utility model, it should be understood that the utility model is not limited to herein
Disclosed form, should not be regarded as an exclusion of other examples, and can be used for other combinations, modifications, and environments, and
Can be in contemplated scope described herein, modifications can be made through the above teachings or related fields of technology or knowledge.And this field
The modifications and changes that personnel are carried out do not depart from the spirit and scope of the utility model, then all should be in right appended by the utility model
It is required that protection scope in.
