Key points are that the circuit board is also provided with a signal output bus which is connected with the control circuit, and a remote communication interface. The control circuit is connected with a display panel arranged on the machine shell via the signal output bus. The control circuit is connected with the remote communication interface. An anti-thunder device deterioration indication, a PDU grounding abnormity indication and a power supply polarity reversion indication are integrated by the anti-thunder power supply distribution unit so that the anti-thunder power supply distribution unit has an anti-thunder device deterioration remote signaling output function, and thus onsite detection and remote monitoring of the PDU anti-thunder state can be realized.
Description
Technical field
The utility model belongs to communication equipment field, relates to a kind of electric power Special lightning protection power distribution unit, is mainly used in overvoltage, the Surge suppression of electric power secondary system machine room terminal equipment.
Background technology
Lightning protection power source allocation units (PDU) designs for installing on standard cabinet, and PDU mainly protects the visual plants such as the interior communication of rack, electronics, avoid causing device damage because of overvoltage and lightning induction.Lightning protection PDU is general only with lightning protection function in the market, status display function not, and remote signaling function, cannot the scene of realizing checks the situations such as its operating state and lightning protection be deteriorated, more can not realize remote signaling function and remote monitoring.Those skilled in the art can not understand the state of PDU internal lighting protection module and ground path well in time, easily cause the operation of PDU device and lightning protection function is impacted.
Summary of the invention
The utility model is in order to overcome deficiency of the prior art, designed a kind of electric power Special lightning protection power distribution unit, the integrated deteriorated indication of lightning protection component, PDU ground connection are indicated extremely, electric power polarity connects anti-indication, possess the deteriorated remote signalling output function of lightning protection component, can realize Site Detection and the remote monitoring of PDU lightning protection state.
The technical solution adopted in the utility model is; a kind of electric power Special lightning protection power distribution unit; comprise casing and be arranged on the circuit board with lightning protection circuit, surge restraint circuit and control circuit in casing; key is: in described circuit board, also comprise and be connected signal output bus and remote communication interface with control circuit; control circuit is connected with the display floater arranging on casing by signal output bus, and control circuit is connected with remote communication interface.
In described circuit board, also comprise grounded inspection circuit, and on the display floater of casing, set up ground state indicator light, electric power polarity indicator light, lightning protection component deterioration indicator light.
Described casing outer surface is also provided with one deck anti-static coating.
On described casing, be also provided with supply hub.
The beneficial effects of the utility model are that circuit adopts two-stage protection, has reduced residual voltage, reduces the harm that surge causes rear class power taking equipment; PDU adopts phosphor bronze, and surface treatment adopts black antistatic spraying technology, and the metal material of PDU socket is better than civilian socket heat-resisting quantity, meets environmental requirement.According to national standard, the intensification index of common socket is not higher than 45 ℃; Modularization PDU can be distributed to power supply on support user, thereby reduces being entangled with of electric wire, installs more flexibly and easily, and has increased the quantity of delivery outlet; The deteriorated remote signalling of lightning protection output, when the built-in lightning protection component of PDU occurs that when deteriorated, state turnover occurs the deteriorated remote signalling output port of lightning protection in time, and can communicate with lightning protection and management system, upload deterioration state, and can long-rangely check its deteriorated time, the information such as state.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
1 represents casing, and 2 represent display floater, and 3 represent remote communication interface, and 4 represent ground state indicator light, and 5 represent supply hub, and 6 represent PDU plug.
Embodiment
A kind of electric power Special lightning protection power distribution unit; the circuit board with lightning protection circuit, surge restraint circuit and control circuit that comprises casing 1 and be arranged on casing 1 interior setting; key is: in described circuit board, also comprise and be connected signal output bus and remote communication interface 3 with control circuit; control circuit is connected with the display floater 2 arranging on casing 1 by signal output bus, and control circuit is connected with remote communication interface 3.
In described circuit board, also comprise ground connection detection, error-polarity connection, lightning protection component degradation circuit, and set up ground state indicator light 4 on the display floater 2 of casing.
Described casing 1 outer surface is also provided with one deck anti-static coating.
On described casing 1, be also provided with supply hub 5.
The side of casing 1 is provided with PDU plug 6, as the power line of lightning protection power source allocation units.
In the specific implementation, the inner integrated power supply lightning-protection module of PDU device, can ensure the power supply of rear class device security to the utility model; Be provided with multiple green indicating lamp, constantly show PDU state, find in time PDU lightning protection degradation failure and reverse power connection fault; Phase line, zero line reversal connection indicator light: when L line and the reversal connection of N line, anti-reverse indicator light is in shinny state; Grounded signal lamp: when the disconnection of PDU earth connection or loose contact, grounded signal lamp is in shinny state; Lightning protection deterioration indicator light: occur that at PDU internal lighting protection device deteriorated time, lightning protection indicator light is in shinny state; Remote signalling output design: the deteriorated remote signalling output of lightning protection can connect that data acquisition unit is connected into lightning protection and detection system is carried out Real-Time Monitoring, reduces on-site maintenance personnel's workload.
The utility model, has solved following practical problem:
1, ground state indication: possess ground state deixis, 19 cun of racks of standard are installed, and in the inner functional module of adding of PDU, detect ground state, do not increase PDU volume, and compatibility standard frame installs, bad and have indication output there is no ground connection in the situation that ground connection.
2, possesses electric power polarity indication: show that intuitively PDU in correct and opposite polarity situation, management equipment personnel can be judged clearly in polarity, the risk that minimizing misoperation brings.
3, possess the deteriorated remote signalling output of lightning protection component and deixis, can detect online and remote monitoring, reduced attendant's the repair and maintenance time; Can find in time fault time and fault point, avoid the unnecessary device damage because being struck by lightning and causing.
