Description

Inflow package faucet facility {oil type package substation}

The automatic breakdown switch 26 is installed in the inflow package up to the primary cable 27 and the secondary cable 33 among the extra-high voltage power receiving facilities to reduce the extra-high voltage insulation distance. Outside the inflow package 14, an automatic control box 22 is installed and a manual input lever 23 and a blocking lever 24 are installed.

As illustrated in FIG. 8, an arrester 30 and a power fuse 29 are installed in the inflow package. As illustrated in Fig. 9, the instrument transformer 36 is installed in the inflow package. As illustrated in FIG. 10, a cutout switch 32 is installed in the inflow package. The power fuse 29 and the cutout switch 32 are installed so that the link is separated downwards during a short circuit or an overload interruption operation and can be rotated 180 ° for easy operation through the handhole 20 during repair or inspection. It is structured. Each package connecting cable is connected terminally in insulating oil for easy connection. On the outside of each package is attached a flow meter and a temperature sensor, and a control box 21 that sounds an alarm when abnormal.

According to this proposal, by installing a combination of special high-voltage receivers in the inflow package, the power receiving equipment can be miniaturized, greatly reducing the area and space, eliminating the lively charging area, reducing the risk of electric shock to the managers, and in particular, reducing the disaster on the construction site. This is to improve the reliability of the electricity supply due to breakdown caused by contact with small animals, rainy weather or dust. It has the advantage of being able to standardize production by each capacity and it can be installed and used as soon as it arrives on site. It is also possible to monitor the charging part and operation part by installing various control sensors in the package.

The present invention relates to an inflow package faucet facility, and more specifically, to the high pressure and special high pressure inflow package faucet facility, which is made by each facility and installed in the inflow package, which is installed and exposed to the air. It is about.

In general, the high-voltage power receiving facilities are largely divided into an angle assembly type (Fig. 1) equipment and a cubicle type (Fig. 3) equipment. In a standard faucet system, a capacity of less than 1000 kiloamps (Amp) will include an automatic breaker switch (1) and an arrester (2), a power fuse (3), a transformer (4), a cutout switch (6) and a transformer (7). Equipment such as these is installed in order. Each facility requires a large area and space due to the distance between the connecting busbar and the installation space, etc., and the exposure of the charging part causes the risk of electric shock and corrosion and failure of the equipment, causing a power outage. The cubicle type faucet is also united in a closed metal enclosure, greatly reducing the installation space, but basically has the same problem by exposing the charging part in the air.

The purpose of the present invention is to reduce the installation area and space, increase the ease and safety of maintenance, improve the appearance of the power receiving equipment, and supply electricity by combining and installing the power receiving equipment except the transformer among the high and special high voltage receiving facilities in the inflow package. To provide an inflow package faucet facility to improve the reliability of the.

According to the present invention, the automatic breakdown switch 26 and the extra-high-pressure inlet cable 27 of the extra-high pressure faucet are connected in the inflow package, and the lightning arrester 30 and the power fuse 29 are connected by cables. The transformer and the cutout switch 32 are connected in sequence. In case of failure of each device, the special high voltage connection cable is easy to remove and detach by terminal type (Fig. 11), and each device is separated by internal isolation wall. A flow meter is installed on the outside of each device package and a temperature sensor is attached. And it is provided with a control box 21 to raise a warning sound when the temperature rises above a certain temperature or lacks a certain flow rate. Handhole 20 is provided at the top for maintenance of each facility, and is easily used for failure or inspection. The power fuse 29 and the cutout switch 32 are designed to allow for external take-out and repair for convenience of maintenance.

As mentioned above, according to the proposal, the installation of high-pressure and extra-high-voltage receivers in the inflow package can greatly reduce the installation area and space, and prevent the electrostatic accidents caused by the electric shock of animals such as birds, cats, mice, etc. due to the elimination of exposed charge parts. Corrosion of the equipment and the failure prevention effect can be obtained, which greatly improves the reliability of electricity supply.

In addition, the safety of residents and managers can be ensured by the concealment of urban aesthetics and dangerous goods, and the miniaturization of inflow packages saves resources, greatly reduces installation labor costs, and can immediately use standard inflow packages.

It is also possible to combine power installations of more than 1000 kilovolt amperes and high voltage power installations in the inlet package.
