Abstract
The utility model discloses an arc-extinguishing, harmonic-eliminating and overvoltage protection device. An upper rail assembly and a lower rail assembly are arranged on both inner sides of a cabinet, an upper handcart is arranged on the upper rail assembly, a lower handcart is arranged on the lower rail assembly, a vacuum contactor or a breaker is mounted on the upper handcart, a voltage transformer and an overvoltage fuse are mounted on the lower handcart, and both the upper handcart and the lower handcart are chassis type handcarts with four rollers; static contact boxes are mounted on thebacks of the vacuum contactor or the breaker and the voltage transformer, and after the handcarts are pushed into the cabinet, all the static contact boxes are connected with a main circuit. When thedevice is assembled, the upper handcart and the lower handcart are pushed into the cabinet along the rails by means of respective rollers; the device can be overhauled as long as the handcarts are drawn out of the cabinet, consequently, overhaul and maintenance are convenient, and maintainers do not need to repetitively climb and get into the cabinet.
Description
Technical field
The utility model relates to electric control gear, relates in particular to 10KV central point non_direct ground distribution system extinguishing arc harmonic elimination apparatus.
Background technology
Traditional extinguishing arc harmonic elimination over-pressure safety device comprises in cabinet and the cabinet separately parts such as the single-phase vacuum contactor of control or circuit breaker, voltage transformer, overvoltage protection device, current limiting fuse.Because each parts all adopts fixed installation on mounting means, add that the cabinet size limits, often cause assembling, maintenances, operate when overhauling inconvenient.
Summary of the invention
The purpose of this utility model is to solve aforesaid operations inconvenience problem, and a kind of extinguishing arc harmonic elimination and over-pressure safety device are provided.
For achieving the above object, the utility model improves the mounting structure of existing extinguishing arc harmonic elimination over-pressure safety device.Structure after the improvement is: comprise each parts in cabinet and the cabinet, it is characterized in that: be provided with two groups of guide rails up and down in two inboards of cabinet, place handcart on the last group of guide rail, place handcart down on the following group guide rail, vacuum contactor or circuit breaker are installed on the handcart, voltage transformer and overvoltage fuse are installed on down on the handcart, and last handcart and following handcart are the chassis type handcart that has four wheels; The back of vacuum circuit-breaker or contactor and voltage transformer all is equipped with the fixed contact box, and all fixed contact boxes were connected with major loop after handcart pushed cabinet.
Good effect of the present utility model is: during assembling, the roller of handcart by separately pushes the cabinet cabinet along guide rail up and down; During maintenance, the handcart extraction can be operated outside cabinet, repair and maintenance is convenient, has saved the maintainer and has climbed the heavy work of boring cabinet repeatedly.
