Description
Technical field
The utility model relates to transformer technology field, is specifically related to a kind of transformer case carrying fire-extinguishing function concurrently.
Background technology
Transformer (Transformer) utilizes the principle of electromagnetic induction to change the device of alternating voltage, and main member is primary coil, secondary coil and iron core (magnetic core).Major function has: voltage transformation, current transformation, impedance transformation, isolation, voltage stabilizing (magnetic saturation transformer) etc.Can be divided into by purposes: distribution transformer, full-sealed transformer, combined transformer, dry-type transformer, oil-filled transformer, single-phase transformer, furnace transformer, rectifier transformer etc.Transformer is the device of conversion alternating voltage, alternating current and impedance, when being connected with alternating current in primary coil, just producing exchange flux in iron core (or magnetic core), making to induce voltage (or electric current) in secondary coil.China's Transformer Manufacturing Enterprises about has 1500.Nearly 30 of the manufacturing enterprise of more than 500kV transformer; 220kV and above enterprise about 50; 110kV and following manufacturing enterprise manufacturing enterprise about about 130 of certain scale in scope of statistics.Over nearly 3 years, China produces transformer demand per year all at about 1,500,000,000 kilovolt-amperes.Industry is seen clearly research " transformer market analysis report " and is shown China's transformer industry production capacity about 3,000,000,000 kilovolt-amperes, wherein Shen, west, guarantor three group production capacity about 500,000,000 kilovolt-amperes.Several years ago, China's power construction development is swift and violent, and transformer demand increases sharply, and causes quite a few Transformer Enterprise rapid expansion production capacity domestic, and even indivedual enterprises production capacity is doubled.Since 2009, State Grid's construction speed slows down, and Domestic Transformers demand decreases.Particularly Guo Wang company, Nan Wang company adopt centralized bidding mode to purchase transformer, and low tender price causes competition among enterprises unprecedentedly fierce.In addition, because domestic market competition is miserable, middle marked price, lower than cost price, causes some enterprises to start to walk overseas route, exported product, abroad founds the factory.In addition many companies have started to be devoted to development of new, energy-saving and environmental protection, "smart" products.But the general economic benefit of Domestic Transformers enterprise obviously declines, a lot of enterprise is in loss or loss edge.Sacrificing product quality and going the situation that malice is competed, have even appearred in large quantities of distribution transformer enterprise.In addition, power transformer product Quality Down, rate of failure rise.Distribution transformer state takes out qualification rate and is only 70%.Online operation Accident of Transformer rate is in rising trend, and generation accident transformer nearly 5 years article of manufacture are many, and power grid security is on the hazard.Transformer is made up of iron core (or magnetic core) and coil, and coil has two or more winding, and wherein connect the winding of power supply primary coil, remaining winding is secondary coil.Transformer can produce heat in running, some transformers are due to long-time running, inner part aging can be made, electric leakage sometimes can occur and cause fire, time serious, whole Circuits System can be burnt out, cause personal safety as well as the property safety, some transformer cases have fire-extinguishing function concurrently, and some is dry ice, some water, resource compares waste.
Summary of the invention
The purpose of this utility model is to provide a kind of transformer case carrying fire-extinguishing function concurrently, and its structure is simple, reasonable in design, can reduce occurrence index during transformer leakage, ensure that the security of the lives and property, and can save cost.
In order to solve the problem existing for background technology, the utility model is by the following technical solutions: it comprises transformer case, coil, several coil is provided with in transformer case, it also comprises water tank, screen pack, water-supply-pipe, fire hydrant support, fire hydrant, water tank is provided with above transformer case, screen pack is arranged with in water tank, side, water tank bottom is provided with water-supply-pipe, water-supply-pipe is connected with several fire hydrant, and fire hydrant is fixed on fire hydrant support, fire hydrant support is erected in transformer case, and described water tank is open-type cistern.
Operation principle of the present utility model: water tank is for storing the Natural Waters such as rainwater, and by filter screen filtration, when meeting accident, fire hydrant, by the inductor in it, starts automatically, water spray.
The utility model has following beneficial effect: its structure is simple, reasonable in design, can reduce occurrence index during transformer leakage, ensure that the security of the lives and property, and can save cost.
Accompanying drawing illustrates:
Fig. 1 is structural representation of the present utility model.
Embodiment:
Referring to Fig. 1, this embodiment is by the following technical solutions: it comprises transformer case 1, coil 2, three coils are provided with in transformer case 1, it also comprises water tank 3, screen pack 4, water-supply-pipe 5, fire hydrant support 6, fire hydrant 7, water tank 3 is provided with above transformer case 1, screen pack 4 is arranged with in water tank 3, side, water tank 3 bottom is provided with water-supply-pipe 5, water-supply-pipe 5 is connected with four fire hydrants 7, and fire hydrant 7 is fixed on fire hydrant support 6, fire hydrant support 6 is erected in transformer case 1, and described water tank 3 is open-type cistern.
The operation principle of this embodiment: water tank 3, for storing the Natural Waters such as rainwater, is filtered by screen pack 4, when meeting accident, fire hydrant 7, by the inductor in it, starts automatically, water spray.
This embodiment has following beneficial effect: its structure is simple, reasonable in design, can reduce occurrence index during transformer leakage, ensure that the security of the lives and property, and can save cost.
