The transformer body is positioned in the transformer casing body, and the low-voltage output end of the transformer body is connected with the low-voltage circuit breaker in series. The three-phase low-voltage conveying circuit of the rear part of the low-voltage circuit breaker can be respectively connected with a bimetal chip sensor in series. The utility model has the advantages of simple structure, safe use, strong protective performance and easy maintenance, is generally used for the power distribution system of various places of an industrial district, an inhabitant district, a business center, a high building, etc.
Description
The utility model is a kind of transformer switch combination unit that is used for electric network terminal, belongs to electric power power transformation controller switching equipment.
At present, China's converting equipment commonly used in the electrical network conveying system mainly contains two kinds of forms, and a kind of is with high voltage switchgear, low voltage switchgear and three independent distribution systems of partly forming of transformer; Another kind is that above-mentioned three is combined in the Big Iron, and this combination is called box-type substation.The low pressure output of these two kinds of converting equipments directly and the user link, when overload or fault take place low-pressure side, cause that easily converting equipment breaks down like this, because converting equipment is complicated, maintenance time is longer, so converting equipment can directly influence user's work and life after breaking down; If transformer self breaks down, can not be in time and user's power consumption equipment be separated, can cause the damage of power consumption equipment even burn.
The purpose of this utility model is a kind of transformer switch combination unit of design, and it is simple in structure, and self-protection is strong, and is safe and reliable during use, and easy to maintenance.
The designed transformer switch combination unit of the utility model mainly is made up of transformer housing, transformer body, and transformer body is positioned at the transformer housing, is in series with low-voltage circuit breaker at the low-voltage output of transformer body.
The another kind of transformer switch combination unit that the utility model is designed, transformer are dry-type transformer, are in series with low-voltage circuit breaker at the low-voltage output of transformer body.
The designed transformer switch combination unit of the utility model is oil immersed type or fills the transformer of sulfur hexafluoride gas formula.
In the designed transformer switch combination unit of the utility model, also can be in series with the bimetal leaf transducer respectively in the three-phase low-voltage output circuit at low-voltage circuit breaker rear portion.
In the designed transformer switch combination unit of the utility model, have warning device, to play the effect of warning.
Low-voltage circuit breaker in the designed transformer switch combination unit of the utility model can be positioned in the transformer housing.
Low-voltage circuit breaker in the designed transformer switch combination unit of the utility model also can be positioned on the support of transformer shell external body or dry-type transformer.
The low-voltage circuit breaker of the transformer switch combination unit that the utility model is designed has the protection housing, and the protection housing can be oil immersed type or fill sulfur hexafluoride gas or vacuum.
The designed transformer switch combination unit of the utility model is when using, if transformer generation turn-to-turn itself or interlayer fault and when producing big electric current, at first low-voltage circuit breaker action, cut off load, make transformer be in Light Condition, in order to avoid cause low-pressure side user's power consumption equipment damage and burning of transformer.When combined transformer breaks down; temperature in the transformer housing can rise; after rising to the uniform temperature value; bimetal leaf transducer action causing low-voltage circuit breaker action cutoff low load; make transformer be in Light Condition; thereby the protection transformer, expansion, extension after trying to avert accidents and having an accident.When if overload or fault take place the outer low pressure side, low-voltage circuit breaker cooperates branch's controlling organization, and the fault or the overload of low-pressure side are separated with transformer, prevents that outside accident from extending to transformer inside, thereby plays a protective role.
The advantage of the transformer switch combination unit that the utility model is designed is:
1. safe and reliable, protectiveness is strong, can effectively prevent the generation of various damages or burnout failure, prolongs the useful life of transformer.
2. have warning function, can in time find fault, take measures, prevent major accident.
3. easy to maintenance.If the fault that causes of overload, after fault was got rid of, the joystick by low-voltage circuit breaker can restore electricity.If the fault of transformer itself, replaceable transformer and other element can not damage.
The designed transformer switch combination unit of the utility model is mainly used in the distribution system in various places such as industrial park, residential quarter, commercial center and skyscraper.
Fig. 1 is the structure chart of the designed transformer switch combination unit of the utility model.
Fig. 2 is the circuit diagram of Fig. 1.
Fig. 3 is the structure chart of the designed another kind of transformer switch combination unit of the utility model.
In conjunction with specific embodiments the execution mode and the effect of the designed transformer switch combination unit of the utility model is described further with reference to the accompanying drawings below.
Embodiment 1
Transformer switch combination unit as shown in Figure 1, wherein A figure is a front view, B figure is an end view, mainly form by transformer housing 1, transformer device body 2, transformer device body 2 is positioned at transformer housing 1, dielectric in the transformer housing 1 is an oil, and low-voltage circuit breaker 3 and bimetal leaf transducer 4 are placed in the transformer housing 1, and the outside of transformer housing 1 is equipped with the joystick 6 of indicator light 5 and low-voltage circuit breaker.The circuit diagram of transformer switch combination unit as shown in Figure 2, the low-voltage output of transformer device body 2 is in series with low-voltage circuit breaker 3, is in series with bimetal leaf transducer 4 respectively in the three-phase low-pressure delivery circuit at low-voltage circuit breaker 3 rear portions.Have warning circuit at low-pressure end, constitute by induction coil 7, contact switch 8 and indicator light 5 series connection.When transformer switch combination unit is worked; when if transformer device body 2 is short-circuited; low-voltage circuit breaker 3 disconnects; cut off load; make transformer be in Light Condition, while contact switch 8 closures, indicator light 5 is bright; play the warning effect, can protect power consumption equipment effectively and prevent that overcurrent from burning transformer.If the oil temperature in the transformer is too high, also can cause low-voltage circuit breaker 3 and disconnect, preventing that transformer is overheated burns.Also will move if overload low-voltage circuit breaker 3 takes place, and make transformer be in Light Condition, with the protection transformer.In when maintenance, the continuous element of transformer switch combination unit outside all can be motionless, and after changing transformer device body 2 or fixing a breakdown, the joystick 6 of operation low-voltage circuit breaker can make distribution system work on, maintenance and easy to use, safe.
