In order to overcome the above-mentioned shortcomings in the prior art, the purpose of this utility model is to provide a grounding wire management device, which can manage the grounding short-circuit line online, and can effectively prevent the occurrence of closing accidents with grounding short-circuit lines, and protect The safety of personal and power grid equipment is ensured. the

In order to solve the above problems, the utility model adopts the following technical solutions: a grounding wire management device, including an installation wire clip and an alarm circuit fixed together with the installation wire clip, a light prompt circuit, a voice prompt circuit and a power supply;

A time relay, a delay contact, a wireless/wired information transmitting device, and the power supply are connected in series to form the alarm loop;

The time relay, the delay contact, the flash lamp bead, and the power supply are connected in series to form the light prompt circuit;

The time relay, the delay contact, a loudspeaker and the power supply are connected in series to form the voice prompt circuit;

The wireless/wired information transmitting device, the flash lamp bead, and the loudspeaker are mutually connected in parallel. the

Preferably: a time relay is installed on the upper end of the installation clamp, the time relay is placed in a housing, and the wireless/wired information transmitting device is installed above the time relay; above the wireless/wired information transmitting device The flash lamp bead is set; the loudspeaker is installed under the time relay. the

The beneficial effects of the utility model are: the device can manage the grounding short circuit online, and at the same time, can effectively prevent the occurrence of closing accidents with the grounding short circuit, and protect the safety of personal and power grid equipment. the

Description of drawings

Below in conjunction with accompanying drawing and embodiment the utility model is described further:

Fig. 1 is the structural representation of the utility model embodiment;

Fig. 2 is the schematic circuit diagram of the utility model embodiment;

In the figure: 1. Flash lamp bead, 2. Wireless/wired information transmitting device, 3. Timing relay, 4. Delay contact 5. Installation clamp, 6. Speaker, 7. Power supply. the

Detailed ways

As shown in Figure 1, a grounding wire management device includes an installation wire clip 5 and an alarm circuit fixed together with the installation wire clip 5, a light prompt circuit, a voice prompt circuit and a power supply. the

A time relay 3, a delay contact 4, a wireless/wired information transmitting device 2, and a power supply 7 are connected in series to form the alarm circuit. the

The time relay 3, the delay contact 4, the flash bead 1 and the power supply 7 are connected in series to form the light prompt circuit. the

The time relay 3, the delay contact 4, a speaker 6 and a power supply 7 are connected in series to form the voice prompt circuit. the

The wireless/wired information transmitting device 2, the flash bead 1, and the speaker 6 are connected in parallel. the

The upper end of the installation clamp 5 is equipped with a time relay 3, and the time relay 3 is placed in a housing, and a wireless/wired information transmitting device 2 is installed above the time relay 3; a flashlight is arranged above the wireless/wired information transmitting device 2 Bead 1; The speaker 6 is installed below the time relay 3. the

When installing the grounding short-circuit line, fix the installation clamp 5 on the wire on the grounding side, and preset the wireless/wired transmitting device 2 to transmit the relevant information to the substation operation management machine; then rotate the switch of the timing relay 3 to select appropriate time. At the same time, when the scheduled time is up, the timing relay 3 is pulled in, the delay contact is closed, and the flash lamp bead 1 and the speaker 6 are activated, the light prompt circuit and the voice prompt circuit are activated, and the on-site personnel can easily locate the grounding short circuit through the flash and sound. position, and remove the grounding short circuit; and at the same time, the wireless/wired transmitting device 2 sends a prompt signal to the substation operation management machine to prompt the remote monitoring personnel. the
