Abstract
The utility model relates to an anti-fault high-voltage vacuum switch cabinet, which is a switch cabinet in a high-voltage power transmission and transformation device. A plurality of chambers are arranged in a sealed cabinet body. The utility model is characterized in that a main bus is folded backwards and is installed in the cabinet body. Both a main switch vacuum circuit breaker and a spring operating mechanism connected with the main switch vacuum circuit breaker are installed in the cabinet body. A ground connecting bus is connected with a plurality of cabinet bodies and then is connected with the ground. An upper isolation switch is arranged at the upper part of a bus chamber. The utility model has the advantages that the height is lowered; the volume and the weight are decreased; the technical parameter is high; the failure rate is low; the operation is convenient. The anti-fault high-voltage vacuum switch cabinet conforms to the national standard and is suitable for being used in an indoor substation.
Description
The utility model relates to the improvement of the switch cubicle structure in a kind of high-tension power transmission and transformation equipment, is a kind of anti-error type high voltage vacuum switchgear cabinet specifically.
The kind of the high-tension switch cabinet of three-phase single busbar connection is a lot, divides with regard to its structure, mainly can be divided into fixed and handcart switch cabinet two big classes.The typical structure of fixed high-voltage switch cubicle is GG-1A (F), though it is simple relatively, but because of bus is contained in the cabinet top, adopt open type, it highly reaches 3400 millimeters, and its too high height is that 3 meters institutes of general chamber height can not hold, and structure is opened wide, be absolutely unsafe, bigger with international standard IEC298 and national standard BG3906.GB11022 gap, therefore often can not be selected; Though the high-tension switch cabinet of handcart-type structure highly has only 2200 millimeters, be lower than general chamber height, its complex structure, make difficulty, the cost height, and because China's machining level is unsatisfactory, do not satisfy the design accuracy requirement of handcart cabinet, cause the failure rate height of handcart cabinet.
The utility model purpose is to overcome the shortcoming in the above-mentioned technology, a kind of architecture advances is proposed anti-error property high voltage vacuum switchgear cabinet, make its double advantage of getting stationary cabinet and handcart cabinet, reduce its height, it is indoor to pack into, and structure is simpler, reduced volume, weight is lighter, and working service is more convenient.Improve its electric property and mechanical performance.
The utility model purpose is realized by following technical scheme: this anti-error type high voltage vacuum switchgear cabinet, in the cabinet that is welded into angle steel and steel plate, include the cable vault, the main switch chamber, relay bungalow, the terminal chamber, the spring operation chamber, cable is housed respectively in each chamber, lightning arrester, last isolating switch, following isolating switch, current transformer, illuminating lamp, hand-power operation and interlocking device are housed on anti-error type high voltage vacuum switchgear cabinet front panel, it is characterized in that main bus bar is installed on the skeleton of the bus-bar room of back upper place in the anti-error type high voltage vacuum switchgear cabinet cabinet, it is indoor and spring operation is indoor that main switch vacuum circuit-breaker of installing at the cabinet internal fixation and spring operation are contained in main switch respectively, both adopt space formula connecting rod to be connected, earth bus connects the cabinet of a plurality of anti-error type high voltage vacuum switchgear cabinets, and ground connection, last isolating switch is installed in bus-bar room top.
The cabinet of anti-error type high voltage vacuum switchgear cabinet is the closed type cabinet that is welded into by the skeleton of shaped steel system and steel plate, have in the cabinet front can open and close door, have a plurality of elongated blinds fenestras as relief hole at the cabinet top.Just in case have an accident, can select ZN28A-10 series vacuum circuit-breaker to replace oil-minimum breaker of the prior art from the blinds fenestra pressure release at top, realized the no oiling transformation of electrical network, and also the technical parameter height, man-computer relation is good, and failure rate is low.
Spring operation is meant CT17 type or CT19 type spring operation, it and ZN28A-10 series vacuum circuit-breaker all are new products of Xian High voltage Apparatus Research Institute exploitation, and the operating mechanism volume of this model is little, combined floodgate energy height, mechanical endurance is long, can opening and closing more than 10,000 times.Earth bus is meant that cross section is 4 * 40 millimeters
2Copper cash.After the casing connection of earth bus with a plurality of anti-error type high voltage vacuum switchgear cabinets, ground connection guarantees safety again, and is more safer than using earthing screw ground connection on each casing in original technology.Last isolating switch and following isolating switch are all selected CN19-10C for use
2The type switch.Last isolating switch is contained in the bus-bar room.When last isolating switch was operated a switch, the main switch chamber was not charged, at this moment can carry out the indoor maintenance of main switch.
The utility model has the advantages that double advantage of having got stationary structure high-tension switch cabinet and handcart-type structure high-tension switch cabinet, because folding behind the bus is put into cabinet, and be closed by cabinet, make the cabinet height drop to 2200 millimeters with low-voltage cabinet with high, be suitable for very much indoor substation and adopt.Chosen the fixed installation of main switch vacuum circuit-breaker again, installed in the coupled spring operating mechanism cabinet, the structure sealing has guaranteed that the degree of protection of cabinet reaches IP2X, has improved the fail safe of operation.Its main components and parts, the new product of selecting Xian High voltage Apparatus Research Institute to develop, matched with devices, technical parameter height, man-computer relation is good, and is easy to operate, and failure rate is low, realized the no oiling transformation of electrical network, owing to reduced height, reduced volume, also alleviated weight, the maintenance of being more convenient for.Meet standard GB 3906 and GB11022,
Embodiment of accompanying drawings:
Fig. 1 is a kind of anti-error type high voltage vacuum switchgear cabinet structure chart,
Fig. 2 is its front view,
This anti-error type high voltage vacuum switchgear cabinet, the cabinet that is welded into angle steel and steel plate, its overall dimension is wide 1200 millimeters, high 2200 millimeters, dark 1500 millimeters, in include cable vault (3), bus-bar room (6), main switch chamber (9), relay bungalow (10), terminal chamber (13), spring operation chamber (15), cable is housed respectively in chamber, lightning arrester (4), following isolating switch (2), current transformer (14), illuminating lamp (11), hand-power operation and interlocking device (12) are housed on the plate in front, main bus bar (17) is contained in the bus-bar room (6) in the cabinet, and main switch vacuum circuit-breaker (5) and connected spring operation (15) are installed in the main switch chamber (9) respectively and in the spring operation chamber (16).Earth bus (1) is that cross section is 4 * 40 millimeters
