Description

DESCRIPTION OF A USEFUL MODEL

ELECTRONIC DEVICE INTENDED FOR USE AS A WORKING COVER OF THE TEST BLOCK

FIELD OF TECHNOLOGY

The utility model relates to electronic devices used in power plants and substations. The above devices are connected to electric circuits of current and voltage, including for performing control, measurement and indication operations.

BACKGROUND

The control, measuring, etc. instruments traditionally used at power facilities are based on blocks for panel mounting, blocks for wall mounting, or blocks for mounting on a DIN rail. For example, shield amperemeters of the CA3020 series and shield voltmeters of the SV3020 series (manufactured by the ZIP-Nauchpribor enterprise (Krasnodar, Russia), see the website http://www.znp.ru) have a version for panel mounting, ALFA A1140 electricity meters (manufactured by Elster Metronika, see, for example, the website http://www.elster.ru/en/574.html) for wall mounting, WS series devices for mounting on a DIN rail (manufactured by Iskra, dd (Slovenia) - see , for example, the site http://www.iskrasistemi.si/products/20071212152244/20071212153441/), etc. The disadvantage of the above devices is that they are installed on a power supply ekte requires branch circuit voltage and current and, consequently, changes circuits chains, extra terminal assemblies, and additional wiring.

Test blocks are also known, which are included in the secondary circuits for their switching and diagnostics, for example, BI test series blocks (eg, BI-4, BI-6) from the manufacturer of the CHEAZ Group of Companies (Cheboksary Electrical Equipment Plant) (Russia) (see , for example, the site http://www.cheaz.ru/en/production/bloki-regulirovaniya/bloki-ispytatelnye-bi-4-bi-4m--bi-6-bi-6m?sphrase_id=57869) or test blocks POCON series from the manufacturer Weidmuller (Germany) (see, for example, the website http://www.wiedmueller.ru/bausteine.net/f/8324/xxxxxxxxxx_PO_POCON_RU_F_INAL.pdf?fd=0).

The above test blocks of both manufacturers have a similar design. The base of the unit contains the main contacts galvanically connected to the corresponding terminals, through which the test unit is connected to current and voltage circuits. A working cover is installed on top of the block base, containing conductive jumpers that ensure the closure of the corresponding main contacts of the block base. Moreover, this cover is a completely passive component that does not contain any additional electronic elements. The above working cover is selected as a prototype of a utility model.

DISCLOSURE OF A USEFUL MODEL

The technical result of the utility model is the elimination of the need to carry out branches of the secondary voltage and current circuits when connecting electronic devices to them at an energy facility.

The proposed device is characterized by the fact that it is made in a form factor that ensures its installation on the basis of standard test units used in current and voltage circuits of power facilities. At the same time, the device contains contacts that provide connection with the corresponding main contacts of the base of the test block in the case of installing the device on the test block, performing the function of the working cover of the test block. A distinctive feature of the device is that it additionally contains an electronic unit enclosed in the device body and connected to the contacts of the device.

BRIEF DESCRIPTION OF THE DRAWINGS

In FIG. 1 is a diagram of the proposed device, describing the composition of its main blocks.

IMPLEMENTATION OF A USEFUL MODEL

The proposed device 1 (see Fig. 1) includes an electronic unit 2 and electrical contacts 3 connected to the unit 2. In this case, the device 1 is made in the form factor, which ensures its installation in the test unit of the secondary circuits instead of the working cover. At the same time, the electronic unit 2 of the device ensures the fulfillment of the functions required from the device, for example, measuring electrical quantities, indication, monitoring the parameters of electrical signals in secondary circuits, storing profiles over time, etc.

Claims (1)

An electronic device designed to be used as a working cover for a test block of secondary circuits, made in the corresponding form factor, which enables the device to be installed in the test block as a working cover, containing at least one electrical contact, which provides connection to the corresponding main the contacts of the base of the test unit when installing this device on a test unit, characterized in that it contains an electronic unit and, at least re, one of the above electrical contacts of the device is connected to the electronic unit.
