Abstract
The utility model relates to a device for processing transformer oil in electric power industry, particularly to a hydroelectric heating system for heating the transformer oil in a vacuum oil filter. The hydroelectric heating system of the vacuum oil filter comprises the vacuum oil filter and is characterized by further comprising a heat exchanger, a water pump and an electric heater, wherein the heat exchanger, the water pump and the electric heater form into a water circulation loop; and the vacuum oil filter and the heat exchanger form into an oil circulation loop. Owing to fast heating, the hydroelectric heating system of the vacuum oil filter reduces damage to the transformer oil effectively, decreases output power of the device greatly and saves energy effectively. In addition, as the heating rate of the transformer oil is relatively stable, the hydroelectric heating system of the vacuum oil filter prevents oil damage caused by local heating, and overheating of the transformer oil.
Description
Technical field
The utility model relates to the equipment of in the power industry transformer oil being handled, and is specifically related to a kind of water power heating system that transformer oil in the vacuum oil-filter is heated.
Background technology
Along with the develop rapidly of power industry, electric pressure, the capacity of domestic power transformer constantly increase, and be also more and more stricter for the equipment requirements of oil processing.At present, transformer oil is heated, adopt contact or electrical heating type mostly, the contact heating causes damage to oil easily; Electrical heating type starts moment, and oily temperature rises sharply, and local heating is prone to cause the transformer oil cracking; In addition, it is big more that transformer oil is handled flow, and the consumed power of electric heater is just big more.
The utility model content
To the technical problem that exists in the prior art, the purpose of the utility model is to provide a kind of vacuum oil-filter water power heating system through intermediary indirect transformer oil.
The technical scheme that the utility model adopts is following:
Vacuum oil-filter water power heating system comprises vacuum oil-filter, it is characterized in that, also comprises heat exchanger, water pump and electric heater, and said heat exchanger, water pump and electric heater are formed water-flow circuit, and said vacuum oil-filter and heat exchanger are formed oily closed circuit.
As preferably, said heat exchanger is a plate type heat exchanger.
Comparatively perfect is,
Said electric heater is provided with safe temperature controller and temp probe.
Also be provided with filter between water outlet place of said heat exchanger and the water pump.
Be provided with expansion drum, Pressure gauge, safety valve and water compensating valve between water inlet place of said electric heater and heat exchanger successively.
Water in the said water-flow circuit is mineral water.
The utility model vacuum oil-filter water power heating system is utilized the heat exchange principle, uses intermediary indirect oil; Promptly earlier add hot water through electric energy; By the heat-exchanger pump people heat exchanger of water pump after, form the recirculation heater system, thereby the oil circuit piping in the heat exchanging device carries out heat exchange again with heater; Improve the oil temperature, and reach the production demand.
Compared with prior art, the utility model firing rate is fast, and heat transfer coefficient is high, effectively reduces the damage to transformer oil, greatly reduces the power output of equipment, has practiced thrift the energy effectively.In addition,, avoided local heat, and the overheated oil product that causes of transformer oil damages because the intensification of transformer oil is more stable.
Description of drawings
For the ease of it will be appreciated by those skilled in the art that the utility model is further described below in conjunction with accompanying drawing.
Fig. 1 is the system architecture diagram of the utility model vacuum oil-filter water power heating system.
Among Fig. 1,1-vacuum oil-filter, 2-heat exchanger, 3-water compensating valve, 4-safety valve, 5-Pressure gauge, 6-expansion drum, 7-safety temperature controller, 8-electric heater, 9-temp probe, 10-water pump, 11-filter.
The specific embodiment
As shown in Figure 1; Vacuum oil-filter 1 is formed oily closed circuit with heat exchanger 2, and circulatory mediator is an oil in the pipeline, and heat exchanger 2, water pump 10 and electric heater 8 are formed water circulation fundamental circuit; Water pump 10 provides water circulation system kinetic energy; Circulatory mediator is a water in the circulation line, preferred mineral water, and mineral water can improve the service life and the saves energy of whole heating system.
In order to improve the performance of water power heating system; Heat exchanger 2 preferred plate type heat exchangers are provided with filter 11, large granular impurity in filter 11 filter pipelines between water outlet place of heat exchanger 2 and water pump 10; Protection water pump 10 and electric heater 8; Be built-in with the netted filter cylinder of stainless steel, easily removable and washable, it is convenient to change.
Import and export at electric heater 8 are equipped with safe temperature controller 7 and temp probe 9, effectively detect and control water temperature, thereby the temperature of control oil satisfies oily demand for heat.
Rising along with the water circulation system temperature; Closed conduct pressure also increases, and Pressure gauge 5 has characterized the pressure in the pipeline, and expansion drum 6 and safety valve 4 are set in the exit of electric heater 8; Expansion drum 6 guarantees the stable of circulatory system pressure, and the protection pipeline is because of variations such as the build-ups of pressure that expands with heat and contract with cold; Safety valve 4 is opened release with the protection circulation line when pressure is increased to certain value, thereby has solved the problem of hypertonia.
Near an end of heat exchanger 2 water compensating valve 3 being set at water circulation return pipe, is that the circulatory system supplies water, and guaranteed water level is in the required state of work.
Above content only is to be given an example and explanation to what the utility model structure did; Under the technical staff in present technique field described specific embodiment is made various modifications or replenish or adopt similar mode to substitute; Only otherwise depart from the structure of utility model or surmount the defined scope of these claims, all should belong to the protection domain of the utility model.
