Abstract
The utility model relates to a transmission and distribution switch apparatus, particularly an external isolation centrally located metal armoring high-voltage switch apparatus which solves the defects of inconvenient overhaul and maintenance of the existing centrally located high-voltage switch apparatus. The utility model has the technical proposal that the external isolation centrally located metal armoring high-voltage switch apparatus comprises a metal armouring housing and a voltage discharge plate arranged at the top of the housing, wherein, the interior of the housing is distributed with a bus room, a relay room, a breaker room and a cable room. The bus room is sealed and installed at the front upper part of the housing, and the relay room is positioned at the back upper part of the housing. The lower part of the relay room is provided with the breaker room, and the lower part of the bus room is provided with the cable room which is provided with an arrester, a grounding switch and a current mutual inductor. The breaker room is provided with a static contact box and a breaker which is installed on a cart which is moved by a wheel track, and a main bus is arranged in the bus room. The utility model is characterized in that the bottom of the breaker room is provided with a leading out drawer which can be moved, the leading out drawer is a closed flat box body, and the surface of the drawer is provided with the leading out track matched with rolling wheels of the cart. The top of the cable room is provided with a drawn track which is telescopic, and the current mutual inductor are fixed on the drawn track.
Description
One, technical field
The utility model relates to a kind of power transmission and distribution switchgear, particularly a kind of outer middle metal-clad high voltage switchgear of isolating.
Two, background technology
Along with developing rapidly of science and technology and power industry; the novel high-pressure switchgear of excellent performance is constantly put on market; especially in recent years; entering of foreign technology; switchgear has obtained further renewal; the circuit breaker of 10KV has moved towards no oiling, and relaying protection develops into computer integrated protection by discrete component, and the manufacturing process of switchgear is by the digital control processing assembled formation that is welded.Though switchgear is greatly improved from aspects such as technical indicator, serviceabilities, the maintenance of the main components and parts in the switching devices makes that maintenance is very inconvenient because the inner space is little.Chinese patent ZL94229610.9 has introduced a kind of " armouring fixed high-voltage switch equipment ", and its whole components and parts all are fixedly mounted in the sheathed structure, makes that maintenance is very inconvenient.
Three, summary of the invention
The utility model technical issues that need to address are: the outer isolation middle metal-clad high voltage switchgear that a kind of maintenance that the critical piece that easily breaks down can be extracted out is provided.
The technical solution of the utility model is: isolate the middle metal-clad high voltage switchgear outward, comprise the metal armouring shell, cover top portion has pressure relief plate, be distributed with bus-bar room in the shell, relay bungalow, breaker chamber and cable vault, the bus-bar room sealing is installed in the shell front upper part, relay bungalow is positioned at the shell upper back, the relay bungalow bottom is a breaker chamber, the bus-bar room bottom is the cable vault, the cable vault is equipped with lightning arrester, earthed switch, current transformer, breaker chamber is equipped with fixed contact box and circuit breaker, circuit breaker is installed in and relies on the handcart that wheel track moves, main bus bar is installed in the bus-bar room, it is characterized in that: can be an active mobile drawer of drawing is housed in breaker chamber bottom, drawing drawer is airtight flat box body, be provided with the extraction orbit that is complementary with the handcart roller on its surface, telescopic extraction track is housed at the top of cable vault, on the extraction track, be fixed with current transformer.
The beneficial effects of the utility model are: owing to when overhauling and safeguarding high voltage switchgear, circuit breaker and current sensor can be drawn outside the apparatus casing, make that installation, dismounting and the replacing of components and parts are very convenient.
Four, appended drawings is among the utility model structural representation figure: 1-bus-bar room, 2-pressure relief plate, 3-relay bungalow, the 4-breaker chamber, the 5-cable vault, 6-lightning arrester, 7-earthed switch, the 8-current transformer, 9-fixed contact box, 10-circuit breaker, 11-main bus bar, 12-draws drawer, and 13-extracts track out
Five, embodiment
With reference to accompanying drawing, the outer middle metal-clad high voltage switchgear of isolating, comprise the metal armouring shell, cover top portion has pressure relief plate 2, be distributed with bus-bar room 1 in the shell, relay bungalow 3, breaker chamber 4 and cable vault 5, bus-bar room 1 sealing is installed in the shell front upper part, relay bungalow 3 is positioned at the shell upper back, relay bungalow 3 bottoms are breaker chambers 4, bus-bar room 1 bottom is cable vault 5, cable vault 5 is equipped with lightning arrester 6, earthed switch 7, current transformer 8, breaker chamber 4 is equipped with fixed contact box 9 and circuit breaker 10, main bus bar 11 is installed in the bus-bar room 1, one can the be active mobile drawer 12 of drawing is housed in breaker chamber 4 bottoms, circuit breaker 10 is installed in and relies on the handcart that wheel track moves, and draws drawer 12 and is airtight flat box body, is provided with the extraction orbit that is complementary with the handcart roller on its surface, telescopic extraction track 13 is equipped with at 5 top in the cable vault, is fixed with current transformer 8 on extraction track 13.
When circuit breaker 10 needs repair and maintenance, at first make circuit breaker 10 be in gate-dividing state, open 4 of breaker chambers again, that extracts indoor bottom out draws drawer 12, adjust extraction orbit, next circuit breaker cart can be drawn the apparatus casing outside, overhaul and safeguard.When current transformer 8 needs repair and maintenance, confirm that at first cable vault 5 is not charged, fastening bolt is unclamped in the release of back Xiamen, takes connection bus apart, can extract current transformer out.
