Abstract

PURPOSE:To eliminate a setting error, a mistake of a subject relay of setting, etc., control a setting, and facilitate setting at site by providing an input part for inputting the relay setting, a display part, a memorizing part, and a control part or the like. CONSTITUTION:An input part 2 inputs a relay setting, a display part 4 displays the inputted value, and a memorizing part 5 memorizes the inputted value. A control part 3 detects a difference by the sort or level of a transmitted/ received signal, and sends a control signal or an alarm display signal to a device. A level detecting part 19 for detecting an input level is connected with the part 2, a determining part 17 for comparing the setting memorized at the part 5 with the detected level at the part 9 is connected with the part 19, and an outputting part 18 for giving an alarming output when an abnormality is determined is connected with the part 17. When a signal from a relay setter is received, a device number is recognized first, and when it is different from a value set by the setter, receiving action is stopped. As a result, a relay setting error or the like is eliminated, and control of the settings or the like is facilitated.

Description

Detailed Description of the Invention

[0001]

FIELD OF THE INVENTION The present invention relates to a protective relay device.

[0002]

2. Description of the Related Art When a protective relay device is settled, it is usually set on site by operating one or one lever, tap, switch or the like. Therefore, if the number of relays to be settled increases, a settling error or an error in the settling target relay is likely to occur.

Further, there has been a situation in which management cannot be performed when the set value is changed on site.

[0004]

SUMMARY OF THE INVENTION An object of the present invention is to provide a protective relay device which eliminates erroneous settling of relays, erroneous setting target relays, etc., manages settling values and facilitates on-site settling. Especially.

[0005]

According to the present invention, an input section for inputting a relay set value, a display section for displaying an input value input to this input section, a storage section for storing the input value, and this storage section. And a control unit that is connected to the input unit and the display unit to control transmission / reception, detects a difference according to the type or level of the transmitted / received signals, and sends a control signal or an alarm display signal to the device. It is a relay device.

[0006]

[Function] Input the settling value to the relay settler on the desk, store the settling values of all the relays, call the settling value with the stored relay settler, send the settling value to the relay, Settle.

[0007]

EXAMPLE An example of the present invention will be described below. FIG. 1 shows an input unit 2 for inputting a relay set value, a display unit 4 for displaying an input value input to the input unit 2, a storage unit 5 for storing the input value, a storage unit 5, an input unit 2, and a display. And a control unit 3 that is connected to the unit 4 to control transmission and reception, detects a difference according to the type or level of the transmitted and received signals, and sends a control signal or an alarm display signal to the device. 2 shows a relay including an input unit 2 for inputting a relay set value, a display unit 4 for displaying the input, a storage unit 5 for storing the input, and a transmitting / receiving unit 6 for transmitting the memory contents. The settling device 1, a receiving unit that receives a signal transmitted from the relay settling device 1, a display unit that displays the received data, a storage unit that stores the data, and a setting unit 23 that sets the device of the relay body, and a relay. The detection part of the basic function of the main body,較部 shows a protective relay device and a control unit.

That is, in FIG. 1, there is an input section 2 for inputting a settling value of a relay, a display section 4 for displaying data of the input section is connected through a control section 3, and a storage section 5 for storing the settling value is provided. The transmission / reception unit 16 which is connected via the control unit 3 and transmits the settling value is also connected in the same manner, and the transmission / reception unit 6 is also connected to the transmission antenna 7.

Then, the settling value input by the input unit 2 is displayed on the display unit 4, and the settling value is stored in the storage unit 5 according to an instruction from the input unit 2.

At the time of input, when the type of protective relay is entered, the setting items are displayed, and the input is made according to them.

For example, in the case of an overcurrent relay, devices, taps, levers, instants, and curve selection Nos.
These data are transmitted to the protective relay by the transmitting unit in the vicinity of the protective relay. As a transmission method, a low power method, an infrared method, a weak radio wave method, etc. are used. Next, referring to FIG.
Is connected, and the control unit 3 for displaying the transmitted signal on the display unit 4 and storing it in the storage unit 5 is connected.

A level detecting section 19 for detecting the input level is connected to the input section 2 for inputting the detection data, and a judging section 17 for comparing and judging the settling value stored in the memory 5 and the detection level in the level detecting section 17. Is connected, and comprises an output unit 18 which outputs an alarm when an abnormality is judged. When receiving the signal from the relay adjuster, first check the device No. sent, and if it is the same as the value set by the device adjuster, the data will be received to the end and stored in the storage unit. At the same time, the set value is displayed on the display unit 4. In other cases, the reception is stopped at that point.

[0013]

In the present invention, the setting error of the relay,
It is possible to eliminate mistakes in the relay to be settled, and to manage the settling value and facilitate on-site settling.
