Description

Novel passive protection device

Technical Field

The utility model relates to a power supply unit protection device especially relates to a novel passive protection device.

Background

The passive protection device is also called a self-powered protection device (EPS, EPR, EPH), is mainly applied to transformer protection and line protection of a modern smart grid system, and is specially used for protection of a switch cabinet below 35 KV. The passive protection means that energy is mutually inducted from a high-voltage cable through a mutual inductor, and a switching power supply is designed through a modular electric technology to be used for a digital circuit to work. Traditional passive protection device places into the casing internal assembly with elements such as CPU board, collection and power supply winding, battery, and the shell body is in the encapsulated situation during use, through the passive protection device of long-time use, its inside battery life can shorten, seriously influence the electric charge capacity of battery, must change, and the staff need take off protection device from power supply unit this moment to will dismantle through the apron of screw fixation on the casing, carry out the battery and change then. This kind of operating mode also need pull out the data transmission cable that is connected with external equipment when dismantling the apron, and is fairly loaded down with trivial details, influences the efficiency that the battery was changed and is maintained.

SUMMERY OF THE UTILITY MODEL

The utility model aims to solve the technical problem that overcome prior art not enough, provide one kind and be convenient for carry out the battery and change, simplify equipment battery and maintain a novel passive protection device that the process effectively improved operating efficiency simultaneously.

The utility model adopts the technical proposal that: the utility model discloses a shell body, setting are in inside CPU board, interface board and the setting of shell body are in shell body front end and with CPU board electric connection's operating panel still be provided with in the shell body and gather power supply winding and battery the shell body corresponds battery window has been seted up on the battery one end lateral wall, the battery window through with the battery apron of the detachable assembly of shell body seals.

Further, the battery window and the battery cover plate are both in a square design, and two ends of the battery cover plate are fixedly connected with the outer shell through screws.

Furthermore, an upper sliding groove and a lower sliding groove are respectively arranged at the upper end and the lower end of the battery window, and the battery cover plate can be in sliding fit with the outer shell through the upper sliding groove and the lower sliding groove.

Furthermore, a plurality of fixing studs matched with the acquisition power supply winding are arranged in the outer shell.

Further, operating panel is last be provided with liquid crystal display, operating button and miniUSB interface, liquid crystal display adopts horizontal display design.

And finally, a plurality of wiring holes matched with the interface board are formed in the back panel of the outer shell.

Compared with the prior art, the beneficial effects of the utility model are that: the utility model discloses abandoned and opened the scheme that whole protection device carries out the battery and change through dismantling the back shroud among the traditional art on the shell body, correspond set up a square battery window on the side surface that the battery set up the position to install through the mode of fix with screw, like this in follow-up change or maintenance to the battery, only need twist out and be used for fixing after the battery apron is taken off to the screw of battery apron, can be right battery in the shell body is changed or is maintained, need not to dismantle whole equipment again, has improved the convenience and the operating efficiency that the battery was changed and was maintained greatly, also can avoid dismantling the damage that the in-process caused other spare parts in the past simultaneously. Therefore, the utility model discloses be convenient for carry out the battery and change, simplify equipment battery and maintain the process and effectively improve operating efficiency simultaneously.

Detailed Description

As shown in fig. 1, fig. 2, fig. 3, fig. 4, fig. 5 and fig. 6, the utility model discloses an outer shell 1, setting are in inside CPU board 2, interface board 3 and the setting of outer shell 1 front end and with CPU board 2 electric connection's operating panel 4 still be provided with in the outer shell 1 and gather power supply winding and battery outer shell 1 corresponds battery window 5 has been seted up on the battery one end lateral wall, battery window 5 through with the battery apron 6 of the detachable assembly of outer shell 1 seals. The shell body 1 and the battery cover plate 6 are made of aluminum alloy materials, the structure is light and attractive, and the installation is convenient, so that the compact installation condition of the ring main unit is very suitable. In this embodiment, battery window 5 with battery apron 6 is square design, and battery apron 6 both ends pass through screw 7 with shell body 1 fixed connection, when needs are maintained or are changed the inside battery, only need through demolising screw 7 takes down battery apron 6 can demolish the battery, need not to pull down whole equipment from power supply unit, opens the back lid again and just can take off the battery. In another embodiment, an upper sliding groove 8 and a lower sliding groove 9 are respectively disposed at the upper end and the lower end of the battery window 5, and the battery cover plate 6 can be in sliding fit with the outer casing 1 through the upper sliding groove 8 and the lower sliding groove 9. This kind of design can let battery apron 6 with the shell body better assembles, before not having screwed on screw 7, battery apron 6 also can not drop, the operating personnel of being more convenient for carries out work.

The utility model discloses in be provided with in the shell body 1 a plurality of with gather the fixing stud 10 of power supply winding looks adaptation, under the general condition, gather the total three wire winding of power supply winding, consequently be provided with threely in the shell body fixing stud 10, for further utilization space in the shell body 1 is three fixing stud 10 is triangle-shaped and arranges, through fixing stud 10 installs gather the power supply winding reliable and stable difficult coming off.
