Abstract
The utility model relates to the field of power distribution networks, in particular to a prefabricated substation with a remote/field switching control box mounted on a looped network cabinet. The prefabricated substation with a remote/field switching control function comprises a high-voltage looped network cabinet (1), wherein voltage transformers (2) with fuse protections are mounted above the high-voltage looped network cabinet (1); the remote/field switching control box (3) is mounted on the right side of the high-voltage looped network cabinet (1); clamping current transformers (4) are clamped on an outlet cable of the high-voltage looped network cabinet (1); and a system is formed by the high-voltage looped network cabinet (1), the voltage transformers (2), the current transformers (4) and the remote/field switching control box (3) via the cables and controlled lines. By adopting the prefabricated substation with the remote/field switching control function, signals can be timely transmitted to a control room once a circuit breaks down, so that failures can be rapidly removed, the power-off area can be narrowed, and the field maintenance can be conducted after a switch is switched.
Description
Technical field
The utility model relates to power supply distribution field, specifically relate to a distant place on the spot the conversion and control case be installed in the preassembled transformer station of ring main unit.
Background technology
Increasingly mature along with domestic distribution automation technology, power consumer is had higher requirement to power supply quality, adopt the preassembled transformer station of automated control technology can guarantee the continuity of powering, improve power supply reliability and the quality of power supply, realization remote monitoring and management.The band distant place conversion and control case preassembled transformer station that is installed in ring main unit on the spot can be satisfied when line failure and can in time be sent to the control room with fast number, so that fix a breakdown rapidly, dwindles power supply interrupted district; Behind the change over switch, also can safeguard at the scene.
But, how in transformer station, to realize the prepackage of Distribution Automation Technology, still be a technical barrier of this area so far.
Summary of the invention
The purpose of this utility model is to realize the prepackage of automated control technology in transformer station, improves transformer station's power supply reliability and the quality of power supply, realization remote monitoring and management, and the purpose of this utility model is so to realize.
The utility model provide a kind of in the ring main unit of preassembled transformer station the mounting strap distant place configuration structure of conversion and control case on the spot, can in time be sent to the control room, the purpose of fixing a breakdown rapidly to reach when the line failure with fast number.
Purpose of the present invention is realized by following technical scheme.
A band distant place is the preassembled transformer station of conversion and control on the spot, comprises the high pressure ring cabinet, it is characterized in that:
The voltage transformer of band fuse protection is installed in the top of high pressure ring cabinet; band distant place conversion and control case on the spot is installed in the right side of high pressure ring cabinet; the cassette current transformer is stuck on the high pressure ring cabinet outlet cable, by cable and control line with high pressure ring cabinet, voltage transformer, current transformer, a band distant place on the spot the conversion and control case form a system.
Further, the on-load switch that described high pressure ring cabinet ring advances to encircle out is installed motor-operating mechanism, at the indicating device of the 10kV line side of high pressure ring cabinet config failure electric current.
Specifically: the on-load switch that high pressure ring cabinet ring advances to encircle out is installed motor-operating mechanism, at the indicating device of the 10kV line side of ring main unit config failure electric current, as the section of judgement accident.The voltage transformer of band fuse protection is installed in the top of ring main unit; band distant place conversion and control case on the spot is installed in the right side of ring main unit; the cassette current transformer is stuck on the ring main unit outlet cable, by cable and control line ring main unit, voltage transformer, current transformer, signal controlling case is formed a system.During line failure, signal in time is delivered to the control room, makes the attendant can accurately differentiate time of failure, improves the accident analysis ability, guarantees the distribution network safe operation.
Adopt advantage of the present utility model, adopt the preassembled transformer station of automated control technology can guarantee the continuity of powering, improve power supply reliability and the quality of power supply, realization remote monitoring and management.Band disclosed by the invention distant place conversion and control case on the spot is installed in the preassembled transformer station structure of high pressure ring cabinet, satisfied when line failure and can in time be sent to the control room,, dwindled power supply interrupted district so that fix a breakdown rapidly with fast number, behind the change over switch, also can safeguard at the scene.
Description of drawings
Fig. 1 is the utility model band distant place configuration structure schematic diagram of a kind of execution mode of the preassembled transformer station of conversion and control on the spot.
Among the figure: 1, high pressure ring cabinet, 2, voltage transformer, 3, a distant place/on the spot conversion and control casees, 4, current transformer.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Power network line breaks down or when unusual, electric current and voltage will fluctuate, and will cause the motor-operating mechanism action of ring main unit when surpassing set point, the on-load switch of disconnection ring main unit.In time cut off distribution line, avoid fault to enlarge, protection power network line and grid equipment.Simultaneously, communicate information to the control room,, dwindle power supply interrupted district and time so that can fix a breakdown rapidly by signaling interface.
Claims (2)
1. be with the distant place preassembled transformer station of conversion and control on the spot, comprise high pressure ring cabinet (1), it is characterized in that:
The voltage transformer (2) of band fuse protection is installed in the top of high pressure ring cabinet (1); band distant place conversion and control case (3) on the spot is installed in the right side of high pressure ring cabinet (1); cassette current transformer (4) is stuck on high pressure ring cabinet (1) the outlet cable, by cable and control line with high pressure ring cabinet (1), voltage transformer (2), current transformer (4), a band distant place on the spot conversion and control case (3) form a system.
2. according to the described band of claim 1 distant place preassembled transformer station of conversion and control on the spot, it is characterized in that the on-load switch installation motor-operating mechanism that described high pressure ring cabinet (1) ring advances to encircle out, at the indicating device of the 10kV line side of high pressure ring cabinet (1) config failure electric current.
