Abstract
The utility model discloses a double-inlet-wire and double-PT cabinet power supply device, which comprises a first PT cabinet and a second PT cabinet. The wire outgoing terminal of the first PT cabinet and the wire incoming terminal of the second PT cabinet are connected together through a flexible wire structure. According to the utility model, the flexible wire structure is composed of a cable. The power supply device is simple in structure. When the power supply device is in use, the flexible wire structure is directly connected with the wire incoming terminal of the first PT cabinet and the wire outgoing terminal of the second PT cabinet inside the double-inlet-wire and double-PT cabinet power supply device. In this way, no switching cabinet is required, so that the cost is greatly saved. Meanwhile, the occupation space is saved and the safety performance is enhanced.
Description
Technical field
The utility model relates to the high voltage power transmission and transforming detection range, relates in particular to the two PT cabinet electric supply installations of a kind of pair of inlet wire.
Background technology
The PT cabinet is the voltage transformer cabinet, generally is directly to be attached on the bus, to detect busbar voltage and to realize defencive function.Its inner main voltage transformer pt, isolation knife, fuse and lightning arresters etc. installed.The power supply of high-voltage board screen top WV is provided by the PT cabinet, and existing P T cabinet shares the WV of going up the screen top, for other outlet high-voltage board provides measurements, metering, protects with power supply etc.
As shown in Figure 1, in 10kV primary system loop, comprise high voltage supply system and outlet cabinet 6 when existing reality is used, described high voltage supply system connects the input of outlet cabinet 6.Described high voltage supply system comprises the two-way inlet wire, the one PT cabinet 1 and the 2nd PT cabinet 3, wherein one road inlet wire is the standby operation mode, but the two-way inlet wire is arranged on same end of incoming cables again, upward (every PT is that the upper end arranges inlet wire 4 but two-way PT can not be connected to the main row of remittance simultaneously, the lower end arranges outlet 5), and the PT cabinet has adopted the segmentation of isolation handcart, the mounting means that PT is fixing, so need between an existing PT cabinet 1 and the 2nd PT cabinet 3 to connect by a conversion cabinet 2, so not only waste resources such as electric power, and need additionally set up a platform switching cabinet 2(and also be the row's of turning over cabinet), moreover take up room.
The utility model content
The purpose of this utility model provides the two PT cabinet electric supply installations of a kind of cost-effective a kind of pair of inlet wire.
The utility model adopts following technical proposals:
A kind of pair of two PT cabinet electric supply installations of inlet wire comprise a PT cabinet and the 2nd PT cabinet, and the end of incoming cables of the leading-out terminal of a described PT cabinet and the 2nd PT cabinet is connected by the flexible cord structure.
Described flexible cord structure is cable.
The utility model is simple in structure, use the flexible cord structure directly to connect the end of incoming cables of first cabinet in the two PT cabinet electric supply installations of two inlet wires and the leading-out terminal of the 2nd PT cabinet, thereby replace original switching cabinet, save cost greatly, and saving is taken up an area of the space, strengthened security performance.
Description of drawings
Fig. 1 is the two PT cabinet electric supply installation structural representations of existing pair of inlet wire;
Fig. 2 is structural representation of the present utility model.
Embodiment
As shown in Figure 1, a kind of pair of two PT cabinet electric supply installations of inlet wire comprise a PT cabinet 1 and the 2nd PT cabinet 3, and the end of incoming cables of the leading-out terminal of a described PT cabinet 1 and the 2nd PT cabinet 3 is connected by flexible cord structure 7.Described flexible cord structure 7 is cable.
The degree of depth of a described PT cabinet and the 2nd PT cabinet is approximately 1.5 meters, and for example the PT cabinet of KYN28A-12 type has difference in height between the end of incoming cables 4 on 1.5 meters the degree of depth and leading-out terminal 5.The utility model directly connects the leading-out terminal 5 of a PT cabinet 1 and the end of incoming cables 4 of the 2nd PT cabinet by using flexible cord structure 7, so not only guarantee former design concept, strengthened security performance again, needn't increase cost because increasing lifting conversion cabinet, also save the shared space of electric power system simultaneously.
Claims (2)
1. the two PT cabinet electric supply installations of two inlet wires comprise a PT cabinet and the 2nd PT cabinet, and it is characterized in that: the end of incoming cables of the leading-out terminal of a described PT cabinet and the 2nd PT cabinet is connected by the flexible cord structure.
2. two PT cabinet electric supply installations of the according to claim 1 pair of inlet wire, it is characterized in that: described flexible cord structure is cable.
