Description
One, technical field
The utility model relates to a kind of counting explosion-proof type power surge guard box.
Two, background technology
The source of electric power system surge is divided into outside (thunder and lightning reason) and inner (electric equipment start and stop and fault etc.), and thunder discharge may occur between the cloud layer or cloud layer inside, or cloud layer over the ground between; Electric power system is inner because the use of large capacity equipment and frequency conversion equipment etc. in addition; bring serious day by day inside surge problem; AC50Hz 220/380V) and the protection of the influence of power consumption equipment and lightning protection and anti-surge to electric power system (Chinese low-voltage power supply system standard:, become the focus that people pay close attention to.
Traditional modular surge protector (SPD); be not equipped with thunder and lightning tally function and remote signalling function; can't inquire about the corresponding time of thunderbolt; therefore can't accurately make the lightning protection scheme and understand local thunderbolt actual conditions, also can cause unattended equipment room but in time not change and cause damage to base station equipment because of the lightning protection device infringement.For common box power surge protector (SPD), do not possess explosion-proof, dustproof, waterproof, multifrequency nature such as anticorrosion, fire-retardant yet.
Three, summary of the invention
At above-mentioned situation; for overcoming the defective of prior art; the purpose of this utility model just is to provide a kind of novel counting explosion-proof type power surge guard box, can effectively solve prevent to be struck by lightning or induction overvoltage that other reason produces, overcurrent phenomenon and other moment surge voltage system or equipment is caused the problem of harm such as permanent damage or instantaneous interruption.
The technical solution adopted in the utility model is, include casing, lightning stroke counter and power control switch, casing is connected with the rotation coupling of lower box through the rear portion by upper box, the upper box internal layer is equipped with lightning stroke counter and the power supply indicator that exposes upper box, be installed with the power control switch and the surge suppressor that fix in the lower box side by side, joint pin is arranged at surge suppressor top, and links to each other with lightning stroke counter, and power control switch connects power supply indicator on the casing through lead.
The utility model good airproof performance, easy-to-connect is installed, is had thunderbolt numeration, dustproof, waterproof, anticorrosion, function such as explosion-proof, fire-retardant.Can prevent to be struck by lightning or induction overvoltage that other reason produces, overcurrent phenomenon and other moment surge voltage system or equipment is caused harm such as permanent damage or instantaneous interruption, have good economic and social benefit.
Four, description of drawings
Accompanying drawing is the utility model structural front view (casing is opened).
Five, embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is done detailed explanation.
Shown in accompanying drawing, the utility model includes casing, lightning stroke counter and power control switch, casing is connected with the rotation coupling 3 of lower box 1 through the rear portion by upper box 2, upper box 2 internal layers are equipped with lightning stroke counter 7 and the power supply indicator 8 that exposes upper box, be installed with the power control switch 5 and the surge suppressor 6 that fix in the lower box 1 side by side, joint pin 4 is arranged at surge suppressor 6 tops, and links to each other with lightning stroke counter 7, and power control switch 5 connects power supply indicator 2 on the casing through lead.
In order to guarantee result of use, said rotation coupling can be hinge or rotation axis.
The thunderbolt register adopts the duplicate rows liquid crystal display, can inquire about the corresponding time of thunderbolt, to formulating the lightning protection scheme and understanding local thunderbolt actual conditions important value is arranged.
For easy to use, leaded hole 9, lower box top.
The utility model under normal circumstances is high-impedance state; when power network line suffers indirect thunder and lightning and direct effects of lightning or other instantaneous overvoltages; in nanosecond, realize the low-resistance conducting state, transient energy spewed out into the earth, simultaneously with overvoltage Limiting in certain protection level.After transient voltage disappeared, the utility model was high resistance state.Thereby do not influence the normal operation of electrical network.The inductance probe of thunder and lightning counter is installed in the earth connection that lightning current sees through, and when lightning current arrives once, inductance probe is gathered the lightning current signal, through signal processing, sends into the display unit of counter controls, writes down one time lightning current.When lightning current arrives once more, write down lightning current again one time.
Technical parameter of the present utility model is as follows:
1, through-current capacity: 80KA (8/20 μ s)
2, rated voltage: 385V
3, residual voltage :≤2.5KV
4, leakage current :≤15 μ A
5, module pairing parameter consistency: 〉=99%
6, counter precision: 2.5ms
Installation of the present utility model and maintenance:
1, the utility model adopts parallel way to be installed in distribution facility or front equipment end.
2, the lightning protection end installation that is connected with the lightning protection grading ring of machine room requires the wiring must be firmly.
3, earth lead cross section＞10mm
2, wire length should not be greater than 1 meter.
4, make regular check on the module window indicating status, normal when green, be damage when red.The module of damage should in time be changed.
5, check overvoltage record number of times and time summer in good time.
The utility model good airproof performance, easy-to-connect is installed, is had thunderbolt numeration, dustproof, waterproof, anticorrosion, function such as explosion-proof, fire-retardant.For common box power surge protector, possessed explosion-proof, dustproof, waterproof, multifrequency nature such as anticorrosion, fire-retardant especially.For traditional modular surge protector, thunder and lightning tally function and remote signalling function have been incorporated.The thunderbolt register adopts the duplicate rows liquid crystal display, can inquire about the corresponding time of thunderbolt, to formulating the lightning protection scheme and understanding local thunderbolt actual conditions important value is arranged.The utility model standard configuration remote signalling terminal, the user can monitor the utility model operating state constantly according to the dynamic monitoring interface, has avoided unattended equipment room but in time not change because of the lightning protection device infringement and has caused damage to base station equipment.
The utility model is used for communication base station (indoor or outdoors) and exchanges single-phase 220V low-voltage distribution (corresponding lightning protection one, two, three) system, can prevent to be struck by lightning or induction overvoltage that other reason produces, overcurrent phenomenon and other moment surge voltage system or equipment is caused harm such as permanent damage or instantaneous interruption.
