The bottom of the stainless steel meter case is provided with two through holes for introducing control cables to the conjunction box; two sides on the back outside the stainless steel meter case are fixedly connected with installing plates; each installing plate is provided with installing holes. The distribution transformation area analog data acquisition standard apparatus is suitable for a distribution transformation auxiliary apparatus which needs distribution transformation of primary current, voltage, etc. of a low voltage side.
Description
Technical field:
The utility model relates to a kind of distribute-electricity transformer district analog data acquisition standard set-up.
Background technology:
Distribution transformer is electric equipment important in the distribution network systems, and the continuous power supply of distribution transforming directly affects safety, reliability and the good service of power supply.In order to guarantee the operation of electricity net safety stable ground, in platform based distribution transformer installing distribution transformer monitoring device and multiple auxiliary equipment, realize Real-Time Monitoring and protection are carried out in distribution.The distribution transforming servicing units such as the monitoring of distribution transformer load, metering device, load collection and imaginary power automatic compensation, the data such as primary current, voltage that all need the distribution low-voltage side, if every covering device is separately installation and operation and maintenance all, equipment cost is higher so, and installation and maintenance is loaded down with trivial details, failure rate is higher, and power supply reliability is low, and major part needs interruption maintenance after these equipment faults.In order to improve power supply reliability, reduce frequency of power cut, save equipment cost, just need a kind of passing through to reserve binding post, the data acquisition unit of the analog quantity wiring of standard is provided for various transformers.
Summary of the invention:
For overcoming the defective of prior art, the purpose of this utility model is to provide a kind of distribute-electricity transformer district analog data acquisition standard set-up, is the distribution transforming servicing unit of the data such as a kind of primary current that all need to be applicable to the distribution low-voltage side, voltage.
The utility model technical solution problem adopts following technical scheme:
Distribute-electricity transformer district analog data acquisition standard set-up, it comprises:
The stainless steel watch case is hinged with the door that can open and close and lock in the front of described stainless steel watch case;
Be fixedly arranged on the base plate on the inner back side of described stainless steel watch case, be installed with voltage, current combined junction box at described base plate; The bottom surface of described stainless steel watch case is provided with two through holes that are introduced into described terminal box for control cables;
The both sides at the outside back side of described stainless steel watch case are fixed with mounting panel, offer installing hole on each described mounting panel.
Compared with the prior art, the beneficial effects of the utility model are embodied in:
1, the utility model device is reserved the analog quantity binding posts such as various device electric currents, voltage, makes things convenient for the transformer wiring.
2, the utility model device integrates rheology, the cable that auxiliary equipment needs, and saves cost.
3, the utility model is simple in structure, and is easy for installation.
4, improve power supply reliability.
Description of drawings:
Fig. 1 stereogram of the present utility model; Fig. 2 is vertical view of the present utility model.(for ease of expressing the structure of table case, all not illustrating the end face of stainless steel watch case among Fig. 1, Fig. 2).
Number in the figure: 1 stainless steel watch case, 2,3 base plates, 4 mounting panels, 5 through holes, 6 combined connection boxes, 7 installing holes.
Below pass through embodiment, and the utility model is described in further detail by reference to the accompanying drawings.
Embodiment:
Embodiment: in conjunction with Fig. 1,2, the distribute-electricity transformer district analog data acquisition standard set-up of the present embodiment, it comprises:
A stainless steel watch case 1, be hinged with the door 2 that can open and close and lock in the front of stainless steel watch case 1, a base plate 3 that is fixedly arranged on the inner back side of stainless steel watch case, be installed with voltage, current combined junction box 6 at base plate 3, the bottom surface of stainless steel watch case is provided with two through holes 5 that are introduced into terminal box for control cables, and be fixed with mounting panel 4 in the both sides at the outside back side of stainless steel watch case, offer installing hole 7 on each mounting panel.
In specifically arranging, size 350 mm of stainless steel watch case * 130 mm * 210mm(length * wide * height), a 300mm * 180mm * 1mm base plate is installed at the back side of table case inside, each makes a call to the circular hole 5 of a Φ 30mm table both sides, case bottom surface, be used for passing through control cables, the front of table case is hinged with a fan size and is the door 2 of 310mm * 190mm, lockable.
1), after safety measure is all finished, the stainless steel watch case 1 that two personnel of ascending a height will be fixed on the cross-arm is fixed on the electric pole by anchor ear.
2), obtaining current: three current transformers are enclosed within on distribution low-voltage side a, b, the c three-phase outlet insulator.Then with control cables wherein an end of three wires connect respectively the S of three current transformers
1On, the other end is connected to inlet wire side a, b in the combined connection box 6, c three-phase current terminal; Again with the S of three current transformers
2By wire link together and with cable wherein an end of a wire be connected, the other end of this root cable conductor is connected on a phase current outlet terminal of combined connection box 6, and couples together with a, b, the c three-phase current outlet terminal of wire with combined connection box 6.When the wiring of current transformer, note the correctness of the polarity of current transformer.
3) power taking is pressed: then the end with remaining four wires of cable is connected with four outlets of distribution low-voltage side respectively, and the other end is connected with the voltage terminal of combined connection box 6 inlet wire sides respectively.
