Abstract

The utility model discloses an outdoor combined-type prepayment circuit breaker. The outdoor combined-type prepayment circuit breaker includes a shell. A voltage transformer is installed on the front side of the top part of the shell. A primary terminal of the voltage transformer is connected with a power source side of the circuit breaker. Pile heads are drawn from an A-phase post and a B-phase post respectively and are connected with a primary terminal of a high-voltage side of the voltage transformer. According to the utility model, advantages of the prior art are maintained, and installation and maintenance of the outdoor combined-type prepayment circuit breaker are facilitated and power interruption frequency and range are reduced at the same time.

Description

Outdoor composite type prepayment breaker
Technical field
the utility model relates to the outdoor vacuum circuit breaker field, is specially a kind of outdoor composite type prepayment breaker.
Background technology
The ZW32-12/630 outdoor high-voltage vacuum breaker is three-phase alternating current 50Hz outdoor high voltage switchgear, is mainly used in cut-offfing, closing load current, overload current and the short circuit current in distribution system.Be applicable to transformer station, industrial and mining enterprises and do protection and control, be more suitable for the place of town and country power distribution network and frequent operation, and can be used as a kind of electrical network and user's demarcation switch equipment and use.Existing prepayment-type circuit breaker ,generally comprise three large parts, i.e. an outdoor vacuum circuit breaker combined electrical apparatus, an outdoor voltage transformer and a measurement control box, the three separates, must be to using the Assembling use of getting up.The vacuum circuit-breaker combined electrical apparatus is comprised of outdoor vacuum circuit breaker and outdoor isolation knife and support thereof.Breaker body adopts all-sealed structure, and vacuum bubbles is sealed in insulating cylinder, and operating mechanism is sealed in housing; Circuit breaker can be installed two-phase or threephase current transformer, for overcurrent and short-circuit protection, also can provide the current acquisition signal to intelligent controller; Outdoor isolation knife is contained in the mains side of breaker body, as obvious fracture.Outdoor voltage transformer separates with circuit breaker combination electrical appliance and is fixed on angle bar frame, and 10KV line voltage is become to alternating current 220V, for prepayment breaker provides energy storage and operating power.Prepayment IC-card table and control loop, warning device are housed in measurement control box, and be connected to breaker mechanism and High-voltage measuring box by control cables, reach the purpose of electricity consumption after accurate control, post-pay paystation, measurement control box generally is contained on electric pole, be positioned at the below of outdoor breaker, be convenient to management.
Above-mentioned this modular breaker, being divided into is three parts, wherein vacuum circuit-breaker combined electrical apparatus and outdoor voltage transformer need near being arranged on special stand, need at twice to upper air installing, so very inconvenient while installing, after installation also irregular, consistency is poor, the space so this circuit breaker has greatly improved.
The utility model content
The purpose of this utility model is to provide a kind of outdoor composite type prepayment breaker, the problem existed to solve prior art.
In order to achieve the above object, the technical scheme that the utility model adopts is:
Outdoor composite type prepayment breaker, comprise housing, case top is equipped with the three-phase pole, in the three-phase pole, A, C two-phase pole rear side are equipped with current transformer by drawing the connection stake respectively, the housing rear side also is equipped with isolation knife, it is characterized in that: the case top installed in front has voltage transformer, a terminal of voltage transformer is connected with the circuit breaker electric source, in the three-phase pole, draw respectively pile crown in the middle of A, B phase pole, the high-pressure side joint of voltage transformer is connected with the pile crown of drawing of A, B phase pole respectively.
Described outdoor composite type prepayment breaker, it is characterized in that: the case top front side is horizontally connected with mounting bracket, and described voltage transformer is arranged on mounting bracket.
The utility model is directly installed on voltage transformer on the breaker mechanism housing, form an all-in-one-piece combination circuit breaker with prepayment metering function, simplified the installation of this equipment, reduced on-the-spot installation difficulty, reduced installation workload, accelerated installation progress, for the user provides larger facility.The utility model, when guaranteeing the prior art advantage, has facilitated the circuit breaker installation, maintenance, has reduced frequency of power cut and scope.
The accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Embodiment
As shown in Figure 1.Outdoor composite type prepayment breaker, comprise housing 1, and housing 1 top is equipped with three-phase pole 4, and wherein A, C two-phase pole 4 sidepieces are equipped with current transformer 3, the other isolation knife 2 that is equipped with of current transformer 3.The utility model is for the outdoor combination circuit breaker of metering device, be fixed with mounting bracket 8 in Shell of circuit breaker top cover front side, draw pile crown 5 in the middle of A, C two-phase pole 4, voltage transformer 7 is installed on mounting bracket 8, and voltage transformer 7 high-pressure side pile crowns connect and draw pile crown 5 by insulated conductor 6.When voltage transformer 7 is carried out to inspection and maintenance, disconnect isolation knife 2 and get final product the cutoff high power supply, voltage transformer 7 is carried out to safe inspection and maintenance.
In the utility model, four stainless steel double-screw bolts of Shell of circuit breaker top cover front side welding, for fixed voltage instrument transformer mounting bracket, dispatching from the factory frontly is fixed to voltage transformer on mounting bracket.Though voltage transformer is installed on the line side of circuit breaker, its terminal is to be connected with the mains side of circuit breaker.By design cleverly, respectively draw one in the centre of circuit breaker A phase and two poles of B phase and draw pile crown, with high-voltage insulating wire, be connected on voltage transformer again, so just form an integral body, just make circuit breaker and instrument transformer can lift to outdoor electric pole mounting bracket simultaneously, the lifting number of times becomes once by twice, has reduced the installation difficulty of prepayment breaker.Be installed on because of instrument transformer the end opening that the circuit breaker line side is also isolation knife simultaneously, so separately circuit breaker, pull open isolation knife and just can cut off the electricity supply, voltage transformer is carried out safe maintenance or changes insurance, rather than must disconnect the upper level switch just can cut off the electricity supply as original, reduced power failure range.

Claims (2)

1. outdoor composite type prepayment breaker, comprise housing, case top is equipped with the three-phase pole, in the three-phase pole, A, C two-phase pole rear side are equipped with current transformer by drawing the connection stake respectively, the housing rear side also is equipped with isolation knife, it is characterized in that: the case top installed in front has voltage transformer, a terminal of voltage transformer is connected with the circuit breaker electric source, in the three-phase pole, draw respectively pile crown in the middle of A, B phase pole, the high-pressure side joint of voltage transformer is connected with the pile crown of drawing of A, B phase pole respectively.
