Description
Technical field
This utility model relates to a kind of monitoring device of transformer, belongs to transformer technology field.
Background technology
In city and rural area, distribution transformer is the important electric power facility being seen everywhere, and its consumption is big, distribution is wide, but lacks the measure effectively supervised it for a long time.That transformer safety is run it is crucial that its operating temperature is unsuitable too high, otherwise can make apparatus insulated damage, accelerated ageing, the lost of life, even burn, lead to the major accident such as fire and blast.The difficult point that network distribution transformer running temperature is carried out monitoring is that transformator is of a great variety, has oil-immersed type transformer, noncrystal transformator, dry-type transformer, box type transformer etc., and mounting means can be ground or underground.
Transformer oil acts primarily as cooling effect when transformator runs, winding etc. is played insulation and insulation maintenance effect, contacting with shunting switch at high-voltage connection and light extinguishing arc effect, prevent the generation of corona and arc discharge, transformer oil is also widely used as the fluid-tight in deadweight safety valve.Owing to transformator riding position is the remotest, the oil of transformator, complete set of equipments etc. often become the theft object of thief, and being easily caused transformator during transformator oil starvation burns, and the interruption of electrical network, and the people and country are caused great property loss.It addition, transformator fluid is during normal use lost less, the most often exists because carelessness checks, cause the damage of transformator.
Utility model content
The deficiency that this utility model exists for prior art just, it is provided that a kind of adsorption-type transformer oil level monitoring alarm device, to monitor transformer oil level, and alarm, prevent transformer damage.
This utility model is realized by following technical proposals.A kind of adsorption-type transformer oil level monitoring alarm device, including pedestal and rely on pedestal install power module, Oil level monitor, display, alarm, Oil level monitor includes single-chip microcomputer, fuel level sensor, modulus conversion chip, man-machine interface and data output, power module connects single-chip microcomputer, display, alarm, single-chip microcomputer connects modulus conversion chip, man-machine interface and data output, modulus conversion chip connects fuel level sensor, data output connects display and alarm, and man-machine interface connects data setting panel.
Described pedestal is magnetic material product, is adsorbed in transformer shell external surface.
Further, also can connect radio transmitting device on single-chip microcomputer, and on display, alarm, connect radio receiver, thus realize remote data transmission and warning.
Level monitoring device of the present utility model can not only be applied to all kinds transformator, warning oil level is arranged voluntarily also dependent on running environment, temperature classification, oil level error, transformator model, simple in construction, cost is low, service life is long, display oil level is intuitively accurate, can install whenever and wherever possible, be easy to the new technique of popularization and application.
Accompanying drawing explanation
Fig. 1 is schematic diagram of the present utility model.
Detailed description of the invention
As shown in Figure 1, a kind of adsorption-type transformer oil level monitoring alarm device, including pedestal 1 and rely on pedestal 1 install power module 2, Oil level monitor, display 9, alarm 8, Oil level monitor includes single-chip microcomputer 3, fuel level sensor 5, modulus conversion chip 4, man-machine interface 6 and data output 7, power module 2 connects single-chip microcomputer 3, display 9, alarm 8, single-chip microcomputer 3 connects modulus conversion chip 4, man-machine interface 6 and data output 7, modulus conversion chip 4 connects fuel level sensor 5, data output 7 connects display 9 and alarm 8, man-machine interface 6 connects data setting panel.
Described pedestal is magnetic material product, is adsorbed in transformer shell external surface.
Radio transmitting device can be connected on single-chip microcomputer 3, and on display 9, alarm 8, connect radio receiver, thus realize remote data transmission and warning.
More specifically, fuel level sensor 5 is formed by connecting with gravity sensor by liquid level buoy, gravity sensor is electrically connected to modulus conversion chip 4, judges oil level by the change of liquid level buoy stress.
Concrete monitoring step is: install a power module 2 on a pedestal that can be adsorbed in transformer shell external surface, and Oil level monitor is installed, fuel level sensor 5 is installed in transformator, the daily situation of change of oil level is monitored by Oil level monitor, when transformer oil in use gradually decreases and makes oil level be less than warning value, this information will be exported on single-chip microcomputer by fuel level sensor 5, transmit out by information on the low side to the concrete numerical value of oil level and oil level by a series of conversions of modulus conversion chip 4, information the most intuitively is seen by display 9, the most also alarm signal can be sent so that power transformation operation personnel can find this defect in time and process by alarm 8.
