Abstract
The utility model relates to a substation dedicated UPS capable of satisfying 103 conventions, which comprises a casing body and a circuit board. The substation dedicated UPS is characterized in that a main power supply circuit is arranged on the circuit board, and consists of an input unit, an input filtering unit, an input isolating unit, a rectifying unit, an inverter unit, an output isolating unit, an output filtering unit, a bypass switching unit and an output unit, which are connected in sequence; a secondary power supply circuit is also arranged on the circuit board, and consists of a bypass input unit, a bypass isolating and pressure-stabilizing unit which are connected in sequence; the main power supply circuit and the secondary power supply circuit switch and supply power through the bypass switching unit; the bypass switching unit carries out control connection with a protection and control unit through a feedback unit. The utility model is suitable for emergency power supplies. Because the UPS can provide a 485 interface which can be connected with the outside and satisfy the 103 conventions, the utility model has the advantages of safety, reliability and high intelligence.
Description
Technical field
The utility model relates to a kind of special-purpose UPS of transformer station that satisfies 103 stipulations, it is a kind of alternating current-direct current dual input, the supply unit that exchanges output, satisfy the designing requirement of power industry transformer substation system fully, have characteristics such as safe and reliable, intelligent degree height, be fit to unattended occasion more.
Background technology
103 stipulations, full name is the IEC60870-5-103 stipulations, is " the relay protection device information interface planning standard " of International Electrotechnical Commission in promulgation in 1997, China adopts this standard at present in the transformer substation system of power industry.The purpose of formulating this planning standard is in transformer station, reaches the purpose of information exchange between different relay protection devices (or unit, interval) and the control system.After adopting this standard, the various device in the transformer station just can clog-free access comprehensive automation system of transformer substation, and the automatization level that this has just improved transformer station greatly realizes the unattended operation and the remote monitoring of transformer station.The special-purpose UPS of common transformer station has only communications protocol and RS-232 or the RS-485 communication interface of oneself, can only use special bitcom to carry out the communication of point-to-point or point-to-multipoint when needing communication.Owing to do not satisfy 103 stipulations, so can't insert in the comprehensive automation system of transformer substation.
The utility model content
The purpose of this utility model is in order to address the above problem, a kind of special-purpose UPS of transformer station that satisfies 103 stipulations is proposed, this UPS adopts dual-cpu structure, and 485 interfaces of satisfied 103 stipulations that link to each other with the external world can be provided, thereby in can clog-free access comprehensive automation system of transformer substation.
The purpose of this utility model is achieved through the following technical solutions: the special-purpose UPS of transformer station that satisfies 103 stipulations; be provided with housing; circuit board; it is characterized in that: described circuit board is provided with by input unit; the input filter unit; the input isolated location; rectification unit; inversion unit; the output isolated location; the output filter unit; the bypass switch unit; the mains supply line that output unit connects to form successively; also be provided with on the described circuit board by the bypass input unit; voltage regulation unit is isolated in bypass; the inferior supply line that the bypass switch unit connects to form successively; mains supply line switches power supply with time supply line by the bypass switch unit; the bypass switch unit is by feedback unit and protection control unit control connection, rectification unit; inversion unit; the bypass switch unit respectively with protection control unit control connection.
The execution mode that the utility model further improves and replenishes:
Described protection control unit is connected with the communication unit data by telecommunication cable.
