Abstract

The invention relates to an automated device for WH power distribution fault diagnosis of a trunk transformer. The device comprises a power plate, a main control board, a power carrier plate, a six-way current transducer, a one-way current transducer, a six-way remote signaling module and a super capacitor pile. The one-way current transducer and the super capacitor pile are connected with the power plate which is connected with the main control board and the power carrier plate; and the power carrier plate, the six-way current transducer and the six-way remote signaling module are all connected with the main control board. Compared with the prior art, the automated device has the advantages that the automated device can collect the current, voltage, active power, degree of ammeter, remote signaling signal, current spillage fault signal and the like of the trunk transformer and uploads the signals to a dispatcher through the power carrier plate. The automated device can work reliably for 10min in the case of power failure of the bus of the trunk transformer to upload the fault signal.

Description

A kind of WH type power distribution fault diagnosis automation equipment that is used for the case change
Technical field
The present invention relates to the change of electric system distribution case, ring main unit, relate in particular to a kind of WH type power distribution fault diagnosis automation equipment that case becomes that is used for.
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, it is not that fault-signal can not in time be uploaded after good place: a, fault took place that case is become the solution that exists at present, has only the operations staff to watch fault-signal to the scene; B, there is not the remote signalling function; C, at jitter when the wireless transmission, unreliable; D, after case became power failure, signal can not be uploaded immediately.
Summary of the invention
Purpose of the present invention is exactly in order to overcome the defective that above-mentioned prior art exists, a kind of safe and reliable WH type power distribution fault diagnosis automation equipment that is used for the case change to be provided.
Purpose of the present invention can be achieved through the following technical solutions: a kind of WH type power distribution fault diagnosis automation equipment that is used for the case change, it is characterized in that, this device comprises power panel, master control board, power carrier plate, No. 6 current transformers, No. 1 current transformer, 6 road remote signal modules, bank of super capacitors, described No. 1 current transformer, bank of super capacitors are connected with power panel, described power panel is connected with master control board, power carrier plate, and described power carrier plate, No. 6 current transformers, 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 present invention realizes electric current, voltage, active power that case is become, electricity, and remote signals, the collection of the out-of-limit fault-signal of electric current etc. also is uploaded to scheduling by power carrier.After the case bus voltage had a power failure, this equipment can be worked 10 minutes reliably, and fault-signal is uploaded.
Description of drawings
Fig. 1 is a kind of structural representation that is used for the WH type power distribution fault diagnosis automation equipment of case change of the present invention.
Embodiment
As shown in Figure 1, a kind of WH type power distribution fault diagnosis automation equipment that is used for the case change, this device comprises power panel, master control board, power carrier plate, No. 6 current transformers, No. 1 current transformer, 6 road remote signal modules, bank of super capacitors, described No. 1 current transformer, bank of super capacitors are connected with power panel, described power panel is connected with master control board, power carrier plate, and described power carrier plate, No. 6 current transformers, 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. 6 current transformers are used to gather 6 road electric currents, are produced electric current Threshold Crossing Alert signal and are uploaded signal to scheduling through the power line carrier plate by master control board.2 road expansion modules are used for self check and spare extension; External special-purpose fault detector signal when 6 road remote signal modules are used for ring main unit and have more line.No. 1 current transformer is used for gathering electric current from the 10kv bus, to the bank of super capacitors charging, produces the equipment required voltage by power panel then then.Because the Current Transformer that makes of native system initiative is bank of super capacitors charging, just makes to install and use and detect automation equipment and upload fault-signal to scheduling and had possible at ring main unit.As long as bus current is greater than 3A, and this equipment just can reliably working.
