Abstract
The utility model relates to a box type fixed metal closed switch device used in a 3-10kV three-phase AC 50 Hz electric power system to receive and distribute electric power, which comprises a cabinet body; a breaker compartment, a main bus compartment, a cable compartment and a relay compartment are arranged in the cabinet body; the cable compartment is arranged behind the breaker compartment; the bus compartment is arranged above the cable compartment; and the relay compartment is arranged above the breaker compartment. The box type fixed metal closed switch device has the advantages that: firstly, the breaker compartment, the main bus compartment, the cable compartment and the relay compartment in the cabinet body are reasonably arranged, so both sides of the box type fixed metal closed switch device are convenient to maintain and debug, and the box type fixed metal closed switch device are small in occupying room and convenient to operate; secondly, a pressure relief channel is arranged in the breaker compartment, so in the case of electric arc in the breaker compartment, the gas can run through the exhaust channel to release the pressure, thus ensuring the equipment to work safely.
Description
Technical field
The utility model relates to the fixed metal enclosed switchgear of accepting in a kind of 3-10KV of being applicable to three-phase alternating current 50Hz electric power system with the usefulness of distributing electric energy of box, belongs to power equipment and makes the field.
Background technology
In electric power system at present, existing fixed formula metal enclosed switchgear mainly is concatenated into the main electrical scheme loop by the requirement of main electrical scheme with isolating switch, circuit breaker, current transformer, with the electric energy inlet highway or by bus electric energy is exported.So general structure is all established two groups of isolating switches in the circuit breaker both sides and many group current transformers satisfy control, safety requirement isolator, do not consider the reasonable construction between cabinet inner breaker chamber, main bus bar chamber, cable vault, the relay chamber more, cause not only that the cabinet size is big, floor space is big, and very inconvenience of operation.
Summary of the invention
Purpose of design: design a kind of both being applicable to and accept in the 3-10KV three-phase alternating current 50Hz electric power system and the usefulness of distributing electric energy, be applicable to the fixed metal enclosed switchgear of box of frequent operation occasion again.
Design: in order to realize above-mentioned purpose of design.1, adopting the design that steel plate separates and the switch cubicle front and back are two-sided between chamber and the chamber, is one of feature of the utility model design.The purpose of doing like this is: both increased the independence and the fail safe of each chamber, can switching devices independently safeguard again, secondary component in the front maintenance relay bungalow, safeguard operating mechanism, mechanical interlocking and running part, the maintenance circuit breaker is safeguarded main bus bar and cable termination to the back.2, the transmission of circuit breaker is connected with operating mechanism by pull bar, circuit breaker lower joint is connected with current transformer, current transformer is connected with the binding post of following isolating switch, the design that the binding post of circuit breaker upper connecting terminal and last isolating switch joins, be the utility model design feature two.The purpose of doing like this is: by the control of pull bar, the upper and lower binding post of circuit breaker is connected with upper and lower isolating switch break-make, thereby has reduced taking of the interior space, make that use is safer.3, the bus in the bus-bar room is the design that product shape is arranged and is connected with last isolating switch binding post, is three of the feature that designs of the utility model.The purpose of doing like this is: reduced the height of cabinet, solved the big problem of space hold.4, circuit breaker is by the design of hand-power actuating and interlocking gear control band mechanical interlocking, be the utility model design feature four.The purpose of doing like this is: make faster and more convenient operation, thereby prevented on-load disconnecting switch, prevented mistake deciliter circuit breaker, prevented mistakenly entering charged chamber, prevented splice grafting ground switch when charged, prevented the function of closing a floodgate, fully satisfied five requirements of preventing with the ground connection cutter.5, the activity in the relay bungalow is installed the design that the little bus of secondary is arranged at various relays and top is housed on the version, be the utility model design feature five.The purpose of doing like this is: be convenient to secondary device is detected, control has increased operability and fail safe.6, breaker chamber, the cable vault design that is equipped with the pressure release exhaust passage and illuminating lamp is housed, be the utility model design feature seven, the purpose of doing like this is: when indoor generation fault electric arc, room pressure raises, pressure relief device has guaranteed the safety of switchgear, the illuminating lamp of connecting inner has made things convenient for and has detected and maintenance simultaneously.
Technical scheme: the fixed metal enclosed switchgear of box, it comprises cabinet, is provided with breaker chamber, main bus bar chamber, cable vault, relay chamber in the cabinet, and the cable vault is positioned at after the branch breaker chamber, bus-bar room is positioned at the top, cable vault, and the relay chamber is positioned at the breaker chamber top.
The utility model is compared with background technology, and the one, by the reasonable construction between cabinet inner breaker chamber, main bus bar chamber, cable vault, the relay chamber, not only can two-sided maintenance and debugging, and also floor space is little, is convenient to operation; The 2nd, the design of breaker chamber internal pressure release channel, when internal arc took place, gas can have been guaranteed the trouble free service of equipment by exhaust by pressure is discharged.
Description of drawings
Fig. 1 is the fixed metal enclosed switchgear structural representation of box.
Embodiment
Embodiment 1: with reference to accompanying drawing 1.The fixed metal enclosed switchgear of box, it comprises cabinet 5, is provided with breaker chamber 1, main bus bar chamber 2, cable vault 3, relay chamber 4 in the cabinet 5, and cable vault 3 is positioned at after the branch breaker chamber 1, bus-bar room 2 is positioned at 3 tops, cable vault, and relay chamber 4 is positioned at breaker chamber 1 top.Adopt steel plate to separate between breaker chamber 1, main bus bar chamber 2, cable vault 3, the relay chamber 4 and switch cubicle is two-sided opens, be convenient to carry out two-sided maintenance.The transmission that is positioned at the vacuum circuit-breaker 6 of breaker chamber 1 is connected by hand-power actuating and interlocking device 8, vacuum circuit-breaker 6 lower joints is connected with current transformer 9, current transformer 9 is connected with the binding post of following isolating switch 10, the binding post of vacuum circuit-breaker 6 upper connecting terminals and last isolating switch 11 joins, be provided with pressure relief channels in the interruption chambe 1, if when internal arc took place, gas can discharge pressure by the exhaust passage, thereby has guaranteed the safety of equipment.In order to reduce the height of cabinet 4, the bus 12 in the main bus bar chamber 2 is the arrangement of product shape and is connected with last isolating switch 11 binding posts, and the supporting insulators in the cable vault 3 are provided with monitoring arrangement.Cabinet 5 is two-sided maintenance type structure, and the secondary component of relay is mainly overhauled in the front, safeguards operating mechanism, mechanical interlocking and running part, and the back is safeguarded main bus bar and cable termination and in breaker chamber and cable vault illuminating lamp is housed.
What need understand is: though the foregoing description is to the utility model detailed text description of contrasting; but these text descriptions; just the simple text of the utility model mentality of designing is described; rather than to the restriction of utility model mentality of designing; any combination, increase or modification that does not exceed the utility model mentality of designing all falls in the protection range of the present utility model.
