Description

Discharging gap protection device
Technical field
It the utility model is related to electric armour clamp technical field, and in particular to a kind of discharging gap protection device.
Background technology
Discharging gap, also known as portable protective gaps, under normal circumstances, portable protective gaps are to insulate over the ground, and dielectric strength Less than the dielectric level of institute's protection circuit, therefore, when circuit is by being struck by lightning, portable protective gaps are breakdown because of overvoltage first, A large amount of lightning currents are leaked into the earth, overvoltage is significantly declined, so as to play a part of protection circuit and electrical equipment.So And the structure design of existing discharging gap protection device is unreasonable, so as to which the discharging gap protection device has installation inconvenience Prompt, the defects of performance is unreliable, lightning protection effect is poor.
The content of the invention
The defects of the purpose of this utility model is to overcome prior art, there is provided it is a kind of it is simple in construction, stable and reliable for performance, The good discharging gap protection device of install convenient, lightning protection effect.
To achieve the above object, the utility model uses a kind of discharging gap protection device, including the insulation of installing plate, column Son, lightning-arrest counter, run-on tab, insulated terminal, insulated overhead conductor, insulation puncture line clamping, described installing plate include installation Portion and bending fixed part, a clamp assemblies are provided with described installation portion, and the clamp assemblies include being arranged on installation portion Drag hook, corresponding drag hook side at be arranged on pressing plate on installation portion, the installation portion of described drag hook, pressing plate and installing plate it Between formed with a holding chamber for being used to clamp cross-arm on electric pole, described lightning-arrest counter be fixed on bending fixed part Place between pressing plate and lightning-arrest counter is corresponded on one end, and on bending fixed part and is fixed with described column insulator, it is described The upper end of column insulator is respectively arranged with run-on tab, insulated terminal, and one end of described insulated overhead conductor is connected to insulation On terminal, the other end of insulated overhead conductor is connected on insulation puncture line clamping.
The beneficial effect of said structure is:The discharging gap protection device by being provided with a clamping group on a mounting board Part, the discharging gap apparatus are installed by the clamp assemblies on cross-arm on utility poles, when mounted, only need to be by drag hook and pressure On the cross-arm of board clamping on utility poles, you can complete the installation of the discharging gap protection device, and discharging gap protection dress Putting also has the advantages of simple in construction, install convenient, stable and reliable for performance, lightning protection effect is good.
Especially, described pressing plate is L-shaped, and a mounting hole is provided with the pressing plate, one is provided with the mounting hole Bolt, bolt is through the through hole on installation portion and has screwed the first nut.Pass through screwing bolts, you can pressing plate is pressed on electric wire It is simple to operate on cross-arm on bar, install convenient.
Especially, the basic configuration of described drag hook is in J-type, and is provided with external screw thread on the periphery wall on the top of drag hook, And the top of drag hook through the mounting hole on installation portion and has screwed the second nut.By screwing the second nut, you can by drag hook Clamp on cross-arm on utility poles, simple to operate, install convenient.
Brief description of the drawings
Fig. 1 is the utility model embodiment structural representation.
Fig. 2 is the structural representation that the utility model clamp assemblies are installed on cross-arm.
Embodiment
As shown in Fig. 1~2, the utility model embodiment is a kind of discharging gap protection device, including installing plate 10, column Insulator 11, lightning-arrest counter 12, run-on tab 13, insulated terminal 14, insulated overhead conductor 15, insulation puncture line clamping 16, it is described Installing plate 10 include installation portion 101 and bending fixed part 102, be provided with a clamp assemblies 20 on described installation portion 101, It is arranged at drag hook 21 that the clamp assemblies 20 include being arranged on installation portion 101, the side of corresponding drag hook 21 on installation portion 101 Pressing plate 22, be used to formed with one between the installation portion 101 of described drag hook 21, pressing plate 22 and installing plate 10 clamp electric wire The holding chamber 200 of cross-arm 30 on bar.As shown in Fig. 2 described pressing plate 22 is L-shaped, an installation is provided with the pressing plate 22 Hole, a bolt 23 is provided with the mounting hole, bolt 23 is through the through hole on installation portion 101 and has screwed the first nut 24. Pass through screwing bolts, you can pressing plate is compressed on cross-arm on utility poles, simple to operate, install convenient.Described drag hook 21 Basic configuration be in J-type, and external screw thread is provided with the periphery wall on the top of drag hook 21, and the top of drag hook 21 passes through installation portion Mounting hole on 101 and the second nut 25 is screwed.By screwing the second nut, you can by the horizontal stroke of drag hook clamping on utility poles It is simple to operate in load, install convenient.Described lightning-arrest counter 12 is fixed on one end of bending fixed part 102, and bending is consolidated Determine to correspond to place between pressing plate 22 and lightning-arrest counter 12 in portion 102 and be fixed with described column insulator 11, described column is exhausted The upper end of edge 11 is respectively arranged with run-on tab 13, insulated terminal 14, and one end of described insulated overhead conductor 15 is connected to absolutely On acies 14, the other end of insulated overhead conductor 15 is connected on insulation puncture line clamping 16.
The discharging gap protection device is passed through by being provided with a clamp assemblies, the discharging gap apparatus on a mounting board On clamp assemblies installation cross-arm on utility poles, when mounted, horizontal stroke that only need to be by drag hook and platen clamp on utility poles In load, you can complete the installation of the discharging gap protection device, and the discharging gap protection device also has simple in construction, installation Convenient, stable and reliable for performance, the advantages of lightning protection effect is good.
