Abstract
The utility model discloses a novel double-side isolated and earthed composite apparatus, comprising an underframe, a breaker and a control panel, wherein the breaker and the control panel are respectively fixed at a left side and a right side of the top surface of the underframe, the breaker is a common-box tank circuit breaker, an upper horizontal output terminal of the breaker is provided with an upper three-position switch, an isolated bus is fixed on the top surface of the upper three-position switch, a lower horizontal output terminal of the breaker is provided with a lower three-position switch, a cable terminal is fixed on the bottom surface of the lower three-position switch, a current transformer is sleeved over the central section of the cable terminal, and a spring mechanism is arranged in the control panel. The novel double-side isolated and earthed composite apparatus provided by the utility model has the characteristics of a novel structure, good reliability, flexible layout, a small floor space and low production cost.
Description
Technical field
The utility model relates to a kind of combined electric equipment for the indoor transformer station of 35KV.
Background technology
As dielectric, along with changes in environmental conditions such as height above sea level, frozen soil, coastal, moist, filths, great changes will take place sharply worsens for its insulation property, can't satisfy the instructions for use under these occasions with air for combined electric product originally.Middle press seal enclosed combined electrical apparatus is the first-generation metal confining gas insulated switching installation of developing at these use problems at first, dwindles the requirement that floor space is reduced investment outlay again to satisfy the power department requirement.Press combined electrical apparatus generally to establish three-station in the routine, can't add time isolating/grounding switch, must close behind the circuit breaker can ground connection, does not meet the user program requirement.
Summary of the invention
For solving the problem of above existence, the utility model provides a kind of novel bilateral to isolate the ground connection combined electrical apparatus, and its technical scheme of taking is:
The circuit breaker and the control panel that comprise underframe and be separately fixed at the underframe end face left and right sides, circuit breaker is for being total to the case potting breaker, the last horizontal output end of circuit breaker is provided with three-station, the end face of last three-station fixedly has isolated bus, the following horizontal output end of circuit breaker is provided with down three-station, fixedly there is cable termination the bottom surface of following three-station, and the middle part of cable termination is with current transformer, is provided with spring mechanism in the control panel.
The utility model adopts directly moving three-station of bilateral, possessing line isolates and the line side earthed switch, the annular straight-through current transformer is realized the global function switch, therefore the utlity model has novel structure, good reliability, flexible arrangement, floor space is little, production cost is low characteristics.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing the utility model is further described.
As shown in Figure 1, circuit breaker 1 and control panel 3 are separately fixed at the left and right sides of underframe 8 end faces, circuit breaker 1 is for being total to the case potting breaker, the last horizontal output end of circuit breaker 1 is established three-station 7, the end face fixed insulation bus 6 of last three-station 7, the following horizontal output end of circuit breaker 1 is set three-station 9, bottom surface attached cable terminal 4, current transformer 5 is enclosed within the middle part of cable termination 4, establishes spring mechanism 2 in the control panel 3.
