Description
Technical field
The utility model relates to switch cubicle field, is specifically related to a kind of for the voltage transformer switching mechanism in gas insulation switch cabinet.
Background technology
Along with the development of electric power system, user is to the fail safe of power equipment, and reliability, parts are easily transsexual is proposed new requirement.
According to market department's requirement, gas insulation switch cabinet is in midwestern power station, and photovoltaic art should occupy one seat.The detection demand needing to meet several different electric pressure power station is detected in power station, and this, with regard to the PT (voltage transformer) needing our switch cubicle to have several groups of electric pressures, switches at any time with the demand of satisfied different electrical network.In the past, we were by artificial method at the scene, manually changed PT.Replacing formality is complicated, and difficulty of construction is large, with duration, and there is the risk of residual voltage in work progress.
For this reason, we have developed in the scheme that can be realized PT handoff functionality by operating mechanism.
Utility model content
The utility model object is: for the problems referred to above, provides a kind of for the voltage transformer switching mechanism in gas insulation switch cabinet, and this mechanism operation is simple, safe and reliable, and time saving and energy saving.
The technical solution of the utility model is: a kind of for the voltage transformer switching mechanism in gas insulation switch cabinet, comprise cabinet and be located at the bus tie be connected in this cabinet and with bus, this switching mechanism also comprises the first fixed contact, the second fixed contact, rotating shaft and moving contact, wherein:
First fixed contact is connected with the second voltage transformer with the first voltage transformer respectively with the second fixed contact, rotating shaft is rotatably provided in cabinet, rotating shaft is connected with the drive rod for driving this rotating shaft to rotate, one end of moving contact is fixed on to contact in rotating shaft and with described bus tie and connects, and the other end is provided with the contact corresponding with described first fixed contact and the second fixed contact.
The utility model, on the basis of technique scheme, also comprises following optimal technical scheme:
Described first voltage transformer is 10KV voltage transformer.
Described second voltage transformer is 35KV voltage transformer.
The utility model has the advantages that: this switching mechanism of the utility model has adapted to the demand in market, solve a difficult problem for switched voltage instrument transformer in switch cubicle at present well, greatly improve the operating efficiency of site operation personnel, also ensure the safety of field maintenance person better simultaneously.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further described:
Fig. 1 is the front view of this voltage transformer switching mechanism of the utility model;
Fig. 2 is the right view of this voltage transformer switching mechanism of the utility model;
Fig. 3 is the left view of this voltage transformer switching mechanism of the utility model;
Wherein: 1-first fixed contact, 2-second fixed contact, 3-rotating shaft, 4-bus tie, 5-moving contact, 6-drive rod, 7-cabinet.
Embodiment
Fig. 1 ~ Fig. 3 illustrates a this specific embodiment for the voltage transformer switching mechanism in gas insulation switch cabinet of the utility model, and it comprises cabinet 7 and is located at the bus tie 4 be connected in this cabinet 7 and with bus.
The key improvements of the present embodiment is: this switching mechanism also comprises the first fixed contact 1, second fixed contact 2, rotating shaft 3 and moving contact 5, wherein:
First fixed contact 1 is connected with the first voltage transformer, and the second fixed contact 2 is connected with the second voltage transformer.Rotating shaft 3 is rotatably provided in cabinet, rotating shaft 3 is connected with the drive rod 6 for driving this rotating shaft to rotate, one end of moving contact 5 is fixed on to contact in rotating shaft 3 and with described bus tie 4 and connects, and moving contact 5 other end is provided with the contact corresponding with described first fixed contact 1 and the second fixed contact 2.
In this example, described first voltage transformer is 10KV voltage transformer, and the second voltage transformer is 35KV voltage transformer.
In the present embodiment, described first fixed contact 1 and the second fixed contact 2 all respectively have three, and corresponding, moving contact 5 also has three, as Fig. 2.
Again shown in composition graphs 1 ~ Fig. 3, now the operation principle of this for the present embodiment voltage transformer switching mechanism is described below:
In Fig. 1 ~ Fig. 3, the tip side of moving contact 5 contacts with the second fixed contact 2 and connects, and is connected with the second voltage transformer by switch cabinet bus, and this switching mechanism is in 35KV voltage transformer closing position.Now, control drive rod 6 (or direct Non-follow control drive rod 6) action by external agency to rotate clockwise in figure 3 to drive rotating shaft 3, rotating shaft 3 drives moving contact 5 to rotate again, and make the end of moving contact 5 leave the second fixed contact 2 and contact with the first fixed contact 1 to connect, thus switch cabinet bus is connected with the first voltage transformer, this switching mechanism is just transformed into 10KV voltage transformer closing position.
Certainly, above-described embodiment, only for technical conceive of the present utility model and feature are described, its object is to people can be understood content of the present utility model and implement according to this, can not limit protection range of the present utility model with this.All equivalent transformations of doing according to the Spirit Essence of the utility model main technical schemes or modification, all should be encompassed within protection range of the present utility model.
