Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a motor-driven device for a transformer equipped with a three-dimensional indicator,

[0001] The present invention relates to a power steering actuator for a transformer which is installed in a substation for supplying a large amount of electric power to a very large plant and a building and serves as a shielding device for protecting main devices connected to the rear end , And more particularly, to allow the field operator to easily check the operation of the electric actuator in the direction of the upper and lower, left and right as well as the front of the electric actuator, The present invention relates to a motor-operated manipulator for a transition vehicle equipped with a three-dimensional indicator.

Generally, in order to minimize the power loss during the transmission process, high voltage is transmitted to the demand site, and the transmitted power must be transformed to a proper voltage before being supplied to the customer. For this reason, regardless of whether it is urban or suburban,

A transformer or substation should be installed.

In this case, the transformer is an integrated device in which most of the devices are housed in a single container, which is a device for down-converting electric power transmitted at a relatively low voltage to a voltage required by a customer and directly delivering the electric power to a customer. On the other hand, the substation is a plant for supplying power to the customer by reducing the power transmitted through the transformer, the breaker, and other devices at a relatively high voltage in the transmission substation. In this case, since the substation processes high-voltage electric power, the electric field formed around the line is very strong. Therefore, in order to prevent arc generation or interference, and to maintain safety, It should be sufficiently insulated.

Generally, a substation is classified into an outdoor substation and an indoor substation depending on the installation location. In a suburban building having a low density of buildings per unit area, a space occupancy cost is lower than an insulation cost, An outdoor substation which is economically advantageous and therefore has a low cost and easy installation is installed on the hearth. On the other hand, in urban areas with a high density of buildings per unit area of the earth, the insulation cost is lower than the space occupying cost, and therefore it is economically advantageous to insulate the elements and the lines from each other economically. Thus, the gas insulated switchgear GIS) type indoor substation is installed.

The circuit breaker used to protect the electrical circuit of the substation in the class of high voltage system or higher is composed of a load switch disconnecting the load current or fault current, a disconnector part for cutting off the line during test or inspection, It is generally composed of a switch part.

Fig. 1A is a diagram showing a single line connection diagram of a breaking device composed of a load break switch 1 and disconnectors 2A and 2B and ground breakers 3A and 3B according to the related art. In the prior art, since the grounding switches 3A and 3B on the primary side and the secondary side of the load switch 1 are used only at the time of inspection, the two grounding switches 3A and 3B are mechanically connected to each other Operated by the operation unit. 1A, the primary disconnector 2A of the load breaker 1, the secondary disconnector 2B of the load breaker 1 and the primary and secondary sides of the load breaker 1 are connected to each other, And three grounding switches (3A, 3B) are to be provided. However, since the operation device according to the prior art transmits power through a three-stage transmission process such as a spindle, a nut, and a crank, the structure becomes complicated and miniaturization becomes difficult, There is a problem in that the installation space is limited. Further, as the structure becomes complicated, it is susceptible to external influence during operation and deterioration or abrasion is generated, thereby deteriorating safety. There is a problem in that reliability of operation is deteriorated by using a speed reducer by combination of pinion gears .

1B, the rotational driving force of the driving motor 10 is transmitted to the worm shaft (not shown) through the planetary speed reducer 20, The worm wheel 40 connected to the worm shaft 30 rotates together with the worm shaft 30 and is switched to an open state or a closed state, 40 and an indicator 60 that rotates together with the indicator 40. The controller 40 is configured to be able to visually check the opening or closing state from the outside. In this way, the indicator 60 of the conventional electric motor for operating the electric power steering system is provided in a two-dimensional planar shape. In order to confirm the opening or closing state of the electric power steering actuator through the indicator 60, There is a problem that it is possible to confirm whether the electric actuator is opened or closed only when the indicator 60 is viewed from the front after moving directly to the electric actuator for the electric vehicle.
