Description
Technical field
The utility model relates to transformer technology field, is specifically related to a kind of anti-ponding transformer.
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.The binding post of existing transformer is just exposed to transformer case outside, due to the gengon that transformer case is regular, top is tabular, when rainy day, sometimes rainwater has little time to get rid of, be easy to the root accumulating in binding post, cause binding post to damage and electric leakage, extremely dangerous.
Summary of the invention
The purpose of this utility model is to provide a kind of anti-ponding transformer, and its structure is simple, reasonable in design, effectively can get rid of by the water effectively bottom pair of wire connection terminals, reduces the probability of electric leakage and damage.
In order to solve the problem existing for background technology, the utility model is by the following technical solutions: it comprises transformer case, binding post, transformer case top is provided with binding post, it also comprises groove, rhone, the bottom periphery of binding post is provided with groove, and the rear side of groove is provided with rhone to transformer case edge.
Operation principle of the present utility model: when rainy, when the rainwater at top falls in a groove, along with rhone spills out, avoids rainwater and overstocks bottom binding post.
The utility model has following beneficial effect: its structure is simple, reasonable in design, effectively can get rid of by the water effectively bottom pair of wire connection terminals, reduces the probability of electric leakage and damage.
Accompanying drawing illustrates:
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the end view of rhone in the utility model.
Embodiment:
Referring to Fig. 1 and Fig. 2, this embodiment is by the following technical solutions: it comprises transformer case 1, binding post 2, the top of transformer case 1 is provided with binding post 2, it also comprises groove 3, rhone 4, the bottom periphery of binding post 2 is provided with groove 3, and the rear side of groove 3 is provided with rhone 4 to the edge of transformer case 1.
The operation principle of this embodiment: when rainy, when the rainwater at top drops in groove 3, along with rhone 4 spills out, avoids rainwater and overstocks bottom binding post.
This embodiment has following beneficial effect: its structure is simple, reasonable in design, effectively can get rid of by the water effectively bottom pair of wire connection terminals, reduces the probability of electric leakage and damage.
