Abstract
The utility model relates to a WX-type power-distribution fault diagnosis automatic device used for a ring network cabinet. The device comprises a power board, a main control board, a powder carrier plate, a three-way current transformer, a three-way voltage transformer and a six-way remote signaling module, wherein the main control board and the powder carrier plate are connected with the powder board, and the powder carrier plate, the three-way current transformer, the three-way voltage transformer and the six-way remote signaling module are respectively connected with the main control board. Compared with the prior art, the utility model realizes the collection to fault signals of the ring network cabinet as well as the monitoring of remote signaling signals and uploads the signals to a dispatching center through the powder carrier plate; and after power failure appears in buses of the ring network cabinet, the device can reliably work for 10 minutes so that the fault signals are uploaded.
Description
Technical field
The utility model relates to the change of electric system distribution case, ring main unit, relates in particular to the WX type power distribution fault diagnosis automation equipment that is used for ring main unit.
Background technology
Shanghai Power Network is the super-huge city electrical network in the fast development.World Expo will be held in 2010 in Shanghai, will become one of international economy, finance, trade, shipping centre to the year two thousand twenty Shanghai, and the socio-economic status in Shanghai has determined electrical network to be one reliability and the quality of power supply required high electrical network.In the Shanghai Urban electrical network, the 10KV ring main unit that gos deep into community is the important step of user's power distribution network power supply quality and power supply reliability.Shanghai City 10KV ring main unit majority is not realized remote monitoring at present, obtains if the ruuning situation of grasp circuit and equipment needs the pipeline rider regularly to ask inspection.Because 10KV ring main unit enormous amount, this way by artificial understanding equipment and circuit ruuning situation, in workload still is very big defective all to be arranged aspect the fault judgement real-time, target for " building the digitizing electric power system; realize power system monitor digitizing, service handling informationization and enterprise operation intensification " in the realization Shanghai Power Company Eleventh Five-Year Plan program for the development of science and technology realizes that the ring main unit remote real time monitoring is significant and urgency simultaneously.But Shanghai 10KV ring main unit majority does not have low pressure 220V power supply, and because ring main unit is of a great variety, factors such as erecting stage complexity are all given the 10KV ring main unit monitored and brought difficulty.At present, the detection of ring main unit has following defective: the back fault-signal takes place fault can not in time upload, and has only the operations staff to watch fault-signal to the scene; There is not the remote signalling function.
Summary of the invention
The purpose of this utility model is exactly in order to overcome the defective that above-mentioned prior art exists, a kind of safe and reliable WX type power distribution fault diagnosis automation equipment that is used for ring main unit to be provided.
The purpose of this utility model can be achieved through the following technical solutions: the WX type power distribution fault diagnosis automation equipment that is used for ring main unit, it is characterized in that, this device comprises power panel, master control board, power carrier plate, No. 3 current transformers, No. 3 voltage transformer (VT), 6 road remote signal modules, described master control board, power carrier plate are connected with power panel, and described power carrier plate, No. 3 current transformers, No. 3 voltage transformer (VT), 6 road remote signal modules all are connected with master control board.
Also comprise expansion module, this expansion module is connected with master control board.
Compared with prior art, the utility model is realized being uploaded to scheduling to the monitoring of the collection of the fault-signal of ring main unit and remote signals and by power carrier, and after the ring main unit bus had a power failure, this equipment can be worked 10 minutes reliably, and fault-signal is uploaded.
Description of drawings
Fig. 1 is the structural representation that the utility model is used for the WX type power distribution fault diagnosis automation equipment of ring main unit.
Embodiment
As shown in Figure 1, the WX type power distribution fault diagnosis automation equipment that is used for ring main unit, this device comprises power panel, master control board, power carrier plate, No. 3 current transformers, No. 3 voltage transformer (VT), 6 road remote signal modules, described master control board, power carrier plate are connected with power panel, and described power carrier plate, No. 3 current transformers, No. 3 voltage transformer (VT), 6 road remote signal modules all are connected with master control board.Also comprise expansion module, this expansion module is connected with master control board.Described power carrier plate is dispatched with the higher level and is connected.
No. 3 current transformers can detect 3 circuitry phase electric currents, and No. 3 voltage transformer (VT) can detect 3 phase voltages, are calculated parameters such as its active power, electricity, power factor then by master control board; Wherein No. 3 current transformers can also doublely be done the out-of-limit detection of 3 phase currents, and provide alerting signal by master control board.Detected various signal is uploaded to scheduling through the power carrier plate again.Become to need detect when having more line at case, 2 road expansion modules are used for the expansion of the system of doing, can external load instrument for measuring and recording, and 6 road remote signal modules can connect special-purpose fault detector.WX type fault diagnosis automation equipment, collection load instrument for measuring and recording, fault detector, carrier terminal equipment realize that price minimizes, on-the-spot simple installationization, equipment dependability increases, but system's flexible expansion.
