Abstract
The utility model discloses a novel low voltage surge arrester, its characterized in that: including lightning arrester body and separation device, separation device include the screw and with the lead screw that a lightning arrester body terminal filament connect, the lead screw through a tin ingot with the screw welding together, the screw still is connected with the earth connection, just the screw with the indicator has been cup jointed to the earth connection junction. Compared with the prior art, the utility model discloses simple structure, reasonable in design can not only the at utmost have given play to arrester or effect when self being out of order too big at the electric current, and the protection cable does not receive the damage with equipment, and when feed through with the low pressure circuit, the engineering time has been saved in conveniently quick construction, has reduced the cost of labor in addition, operates and also compares safety.
Description
Technical field
This utility model relates to lightning arrester technical field, is specifically related to a kind of New Low Voltage spark gap.
Background technology
Height transient overvoltage harm when spark gap is used for protecting electrical equipment against thunderbolt, and limit time of afterflow, the most often limit a kind of electrical equipment of afterflow assignment；Spark gap is otherwise referred to as overvoltage protection device, overvoltage limiter.Spark gap has polytype, and the main operational principle of each type spark gap is different, but their work essence is identical, is provided to protect the communications cable and communication equipment to be without prejudice.Cable and equipment can only be protected when existing common zinc oxide spark gap uses in low pressure to a certain extent without damage, but run into the situation that electric current is excessive, common spark gap does not has due effect, cable and equipment and suffers from certain damage；The most existing spark gap, when connecting with low-voltage circuit, generally requires and pushes cable aside and connect, time-consuming in operation, and does not ensure in safety.
Utility model content
For solving drawbacks described above; the purpose of this utility model is to provide a kind of New Low Voltage spark gap, its simple in construction, reasonable in design, and protection cable and equipment are without damage the most to the full extent; and can connect with low-voltage circuit easily and fast, save the engineering time.
For reaching above-mentioned purpose, the technical solution adopted in the utility model is: a kind of New Low Voltage spark gap, including lightning arrester body and release unit, described release unit includes screw and the screw mandrel with described lightning arrester body one end wire connection, described screw mandrel passes through a block tin together with described screw welding, described screw is also associated with earth lead, and described screw is socketed with indicator with described earth lead junction.Preferably, described lightning arrester body other end wire connection has wiring terminal, and described wiring terminal can be connected with low-voltage circuit by an insulation puncture line clamping.
It is provided with insulating barrier outside described wiring terminal.
Described indicator uses glass fibre to make.
In use, described earth lead end therein is directly embedded in underground to this utility model, and when the electric current running into thunder and lightning weather is excessive, the block tin meeting quick fuse between described screw mandrel and described screw, protection low-voltage circuit and equipment are without damage；When described wiring terminal needs connect with low-voltage circuit, directly passing through insulation puncture line clamping can connect, it is to avoid also need to, in traditional approach, the mode that wire stripping connects.
What this utility model was creative changes traditional lightning protection device into hot melten type spark gap; change the situation that can not play a role completely in the past because of the excessive spark gap of electric current; can be when electric current be excessive or spark gap breaks down; fuse block tin in time; making spark gap disconnect with low-voltage circuit, protection low-voltage circuit and equipment are without damage；The indicator that described screw is provided with described earth lead junction, uses glass fibre to make, and cost is relatively low, can play indicative function when block tin fuses；The insulating barrier being provided with outside described wiring terminal can be when connecting with low-voltage circuit, and operative gets up comparison safety.
Compared with prior art; this utility model simple in construction; reasonable in design; can not only at utmost give play to the spark gap effect when electric current is excessive or self is out of order, protection cable and equipment are without damage, and when connecting with low-voltage circuit; can construct easily and fast; save the engineering time, reduce cost of labor, operate and also compare safety.
Accompanying drawing explanation
Below in conjunction with the accompanying drawings and embodiment, structure and features of the present utility model is further described.
Fig. 1 is structural representation of the present utility model.
In accompanying drawing 1,1. wiring terminal, 2. lightning arrester body, 3. screw mandrel, 4. block tin, 5. screw, 6. indicator, 7. earth lead, 8. earth lead securing member.
Detailed description of the invention
Referring to Fig. 1, a kind of New Low Voltage spark gap, including lightning arrester body 2 and release unit, described release unit includes screw 5 and the screw mandrel 3 with described lightning arrester body 2 one end wire connection, described screw mandrel 3 is welded together with described screw 5 by a block tin 4, described screw 5 is also associated with earth lead 7, and described screw 5 is socketed with indicator 6 with described earth lead 7 junction, and described instruction 6 uses glass fibre to make.Preferably, described lightning arrester body 2 other end wire connection has wiring terminal 1, the outside insulating barrier that is provided with of described wiring terminal 1, and described wiring terminal 1 can be connected with low-voltage circuit by an insulation puncture line clamping.
In use, described earth lead end therein is directly embedded in underground to this utility model, and when the electric current running into thunder and lightning weather is excessive, the block tin meeting quick fuse between described screw mandrel and described screw, protection low-voltage circuit and equipment are without damage；When described wiring terminal needs connect with low-voltage circuit, directly passing through insulation puncture line clamping can connect, it is to avoid also need to, in traditional approach, the mode that wire stripping connects.
This utility model simple in construction; reasonable in design; can not only at utmost give play to the spark gap effect when electric current is excessive or self is out of order; protection cable and equipment are without damage; and when connecting with low-voltage circuit, can construct easily and fast, save the engineering time; reduce cost of labor, operate and also compare safety.
Described above is only preferred embodiment of the present utility model; above-mentioned specific embodiment is not to restriction of the present utility model; retouching, amendment or the equivalent that all those of ordinary skill in the art are made as described above, belongs to protection domain of the present utility model.
