Abstract
Provided is an integrated head knife switch ground wire device which comprises a ground wire panel assembled on a low-voltage distribution box head knife switch. The internal lower end of the ground wire panel is distributed with at least three inserting type connecting blocks capable of being respectively inserted into respective grounding iron core grooves of the head knife switch, and a copper iron clamp which is connected with grounding part is connected with the inserting type connecting blocks on the lower end part of the ground wire panel via aluminum twisted wires. The ground wire panel is made of a transparent plastic plate. The three inserting type connecting blocks distributed in the internal lower end of the ground wire panel are respectively inserted into the three grounding iron core grooves arranged on the head knife switch. Two sides of the ground wire panel are respectively provided with iron hook feet which are used for hooking side grooves of the head knife switch. Therefore, the inserting type connecting blocks can be more precisely aligned with the grounding iron core grooves of the ABB head knife switch, and thus connection is ensured to be reliable. The integrated head knife switch ground wire device has characteristics of being simple in operation and free of repetitive and tedious operations so that operation time is greatly shortened and working efficiency is enhanced.
Description
Technical field
The utility model relates to a kind of ground line configuration of using that the total plug-in strip leading-out terminal of low-tension distribution box is carried out when hanging earthing conductor operates.
Background technology
At present, low-tension distribution box is carried out to the earth connection that the earth connection of hanging earthing conductor use is comprised of 5 iron clamps: one for the earth, being connected, other four A phase, B phase, C phase and zero line places that are clipped in respectively total plug-in strip leading-out terminal.But because the leading-out terminal of low-tension distribution box all is comprised of wide bronze medal, in order to guarantee insulating properties, all can entangle with the insulating sleeve of pyrocondensation, so it is just very little to leave the space of folder bronze medal for, the earth connection of 5 line iron clamps easily be clipped on insulating sleeve or during operation and bronze medal cause and skid, cause ground connection unreliable, complicated operation.
Summary of the invention
The purpose of this utility model is to overcome the deficiency that prior art exists, and provide a kind of, original total plug-in strip earth connection is improved, earth connection is connected more firm with total plug-in strip leading-out terminal bronze medal, operates the grounding wire device of the easier total plug-in strip of integral type.
The purpose of this utility model completes by following technical solution, it comprises an earth connection panel connected on the total plug-in strip of low-tension distribution box, the interior lower end of this earth connection panel is distributed with at least three interior plug-in type contiguous blocks of the iron core slot of ground connection separately that can be plugged in respectively total plug-in strip, is connected in described plug-in type contiguous block, with aluminium stranded conductor, is connected with a copper iron clamp be connected with grounded part in earth connection panel upper and lower end parts.
Described earth connection panel is that a transparent plastic plate is made, and three plug-in type contiguous blocks that distribute in the interior lower end of earth connection panel are plugged in respectively in three ground connection iron core slots that arrange on total plug-in strip.
The both sides of described earth connection panel are respectively arranged be used to catching on the irony hook of total plug-in strip side groove, and the plug-in type contiguous block is aimed in the ground connection iron core slot of the total plug-in strip of ABB comparatively exactly, and what can guarantee to connect is reliable.For convenience of the use of earth connection panel, top is provided with handle 9 outside it.
The utility model is used Integral earthing mechanism, ground connection more reliably; Have simple to operately, need not repeat loaded down with trivial details operation, greatly reduced the operating time, improved the characteristics such as operating efficiency.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is use structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in detail: shown in Fig. 1,2, the utility model comprises an earth connection panel 2 connected on the total plug-in strip 1 of low-tension distribution box, the interior lower end of this earth connection panel 2 is distributed with at least three interior plug-in type contiguous blocks 4 of the iron core slot of ground connection separately 3 that can be plugged in respectively total plug-in strip, is connected in described plug-in type contiguous block 4, with aluminium stranded conductor 5, is connected with a copper iron clamp 6 be connected with grounded part in the bottom of earth connection panel 2.
Described earth connection panel 2 is that a transparent plastic plate is made, and three plug-in type contiguous blocks 4 that distribute in the interior lower end of earth connection panel 2 are plugged in respectively in three ground connection iron core slots 3 that arrange on total plug-in strip 1.
The both sides of described earth connection panel 2 are respectively arranged be used to catching on the irony hook 8 of total plug-in strip side groove 7, and the plug-in type contiguous block is aimed in the ground connection iron core slot of the total plug-in strip of ABB comparatively exactly, and what can guarantee to connect is reliable.
For convenience of the use of earth connection panel, top is provided with handle 9 outside it.
We use two kinds of earth connections to carry out the operation of low-tension distribution box hanging earthing conductor, and then timing respectively obtains following data:
| Detection method | Operate consuming time |
| Use 5 wire | 6 minutes 30 seconds |
| Use novel integrated total plug-in strip earth connection | 1 minute |
Through relatively, use novel integrated total plug-in strip earth connection operating time to shorten 5 times.
