Abstract
The invention discloses an armor moving-open type metal-enclosed switchgear. The armor moving-open type metal-enclosed switchgear comprises a cabinet body, a bus chamber, a breaker handcart chamber, a cable chamber and a relay instrument chamber, wherein the bus chamber, the breaker handcart chamber, the cable chamber and the relay instrument chamber are arranged inside the cabinet body, the bus chamber is located above the position on the back portion of the cabinet body, the cable chamber is located below the bus chamber, the breaker handcart chamber is located in front of the bus chamber, and the bus chamber, the breaker handcart chamber and the cable chamber are provided with pressure releasing devices. A breaker handcart is arranged inside the breaker handcart chamber, and a secondary plug is connected to the position above the breaker handcart. A guide rail and a lead screw are arranged below the breaker handcart, and a drawing type horizontal partition board is arranged below the guide rail. The armor moving-open type metal-enclosed switchgear is reasonable in structure, fast to assemble, safe and reliable, the breaker handcart is operated easily, conveniently and flexibly, a constructor can enter the cabinet body from the front face to carry out installing, debugging and maintaining, the components can be doubly arranged or abut against the wall in a back-to-back mode, the safety and the reliability of the switchgear are improved, and the occupied space is reduced.
Description
Technical field
The invention belongs to power distribution equipment technical field, particularly a kind of armoured.
Background technology
Existing armored mid-set metal enclosed switchgear is because layout is unreasonable, not only maintenance difficulty, and lack safe enough guarantee and safety measure, be both unfavorable for safe operation and the Quick overhaul of equipment, also cannot realize rapid-assembling and the debugging of equipment, and lack operability.
Summary of the invention
The object of the invention is to overcome the defect of prior art, provide a kind of fast and easy assembling, again the armoured of easy access.
It is as follows that the present invention solves the problems of the technologies described above adopted technical scheme: a kind of armoured, comprise cabinet and be arranged on bus-bar room, circuit breaker cart Shi, cable vault and the relay control room in cabinet, described bus-bar room is positioned at cabinet back upper place, described cable vault is positioned at bus-bar room below, described circuit breaker cart chamber is positioned at bus-bar room the place ahead, and described relay control room is positioned at top, circuit breaker cart chamber; Described bus-bar room, circuit breaker cart Shi Ji cable vault all arrange pressure relief device; The indoor circuit breaker cart that arranges of described circuit breaker cart, described short-circuiting device handcart top connecting secondary plug; Described circuit breaker cart below arranges guide rail and leading screw, and described guide rail below arranges pull-out type horizontal baffle.
Described cabinet adopts modular construction, with staking nut and high-intensity bolted on connection, forms;
Described circuit breaker cart arranges mechanical interlocks;
Bus is installed in described bus-bar room top, and current transformer is installed in below;
Described cable vault installing cables, earthed switch, lightning arrester;
The secondary device of relaying protection element, instrument, electrification display and specific (special) requirements can be installed in described relay control room.
Principle: circuit breaker cart adopts leading screw to advance, exit, operation light and flexible, when handcart need to be removed cabinet, just can conveniently take out with a dedicated operation car, carries out various inspections, maintenance; And employing middle, whole handcart volume is little, and it is all extremely convenient to check, safeguard.
Cabinet adopts modular construction, with staking nut and high-intensity bolted on connection, forms, and makes like this processing cycle short, and component universality is strong, and floor space is few, is convenient to tissue and produces.
Switchgear adopts middle, and current transformer, earthed switch are contained in compartment rear portion, and lightning arrester is installed on compartment rear lower, thereby space, cable vault is larger.After short-circuiting device handcart and withdrawable horizontal baffle are removed, workmen just can enter from front installation and maintenance in cabinet.
The mechanical interlocking energy Reliable guarantee handcart of circuit breaker cart is only in service position or test position, and circuit breaker just can close a floodgate; And handcart is only at gate-dividing state, circuit breaker could move.
The contact of the secondary line on switchgear and the secondary line of circuit breaker cart is to realize by manual secondary plug.The moving contact of secondary plug is connected by a nylon bellows and handcart, and secondary fixed contact pedestal is contained in the upper right side of circuit breaker cart chamber.Secondary plug can be plugged and pull up to circuit breaker cart only, when test/open position,, and circuit breaker cart is due to mechanical chain effect when service position, and secondary plug is locked, can not be pulled up.Because the switching-on mechanism of circuit breaker cart is by locked with electromagnet, circuit breaker cart secondary plug do not connect can before only can carry out separating brake, cannot make its combined floodgate.
In circuit breaker cart chamber, the top of bus-bar room and cable vault is equipped with pressure relief device, when circuit breaker or bus generation Internal faults arc, follow the appearance of electric arc, inside switch cabinet air pressure raises, and the special seal circle being installed on door is closed, and the pressure release metallic plate of top equipment will be opened automatically, release pressure and excretion gas, can guarantee the safety of operating personnel and switch cubicle.
Beneficial effect: the present invention is rational in infrastructure, assembling fast, safe and reliable, circuit breaker cart operation light and flexible, workmen can enter from front and in cabinet, carry out Installation and Debugging and maintenance, thereby can form back-to-back dual arrangement or install by wall, improving fail safe, the flexibility of switch, reducing floor space.
