Abstract
The utility model provides a drop-out recloser which is able to reclose or drop according to failure conditions. The drop-out recloser comprises an insulator. A connector base is disposed at one end of the insulator, and a lower contact is disposed at the other end of the insulator. The drop-out recloser is structurally characterized in that the upper contact is disposed on the connector base, a pressure spring is disposed between the upper contact and the connector base, the upper contact is clamped to the upper end of a moving contact, the lower end of the moving contact is electrically connected with one terminal of the recloser, and the other terminal of the recloser is electrically connected with the lower contact through a connecting shaft, and a control part of the recloser controls the moving contact to act to separate the upper contact from the recloser according to reclosing times.
Description
Technical field
The utility model belongs to the high voltage protective technical field of electric appliances, relates in particular to a kind of drop type automatic circuit.
Background technology
In 10kV electric power system at present, most of transient faults occur on the distribution line branch line, and this fault brings user's loss and on the branch line impact, fuse switch is commonly used for a kind of protective switch of the short circuit in order to reduce.On the distribution line branch line, fuse switch is done quick-break when protection, excision be all protection range internal faults, cause that on branch line, all users are forced to outage; When fuse switch is done backup protection, though can to avoid be all protection branch line fault at every turn, can cause that on main line, all users experience instantaneous power breakdown, and can not be used for major break down electric current area.
Summary of the invention
The utility model is exactly for the problems referred to above, and a kind of drop type automatic circuit that can overlap or fall according to failure condition is provided.
For achieving the above object, the utility model adopts following technical scheme, and the utility model comprises insulator, insulator one end is provided with junction block, the insulator other end is provided with lower contact, is provided with upper contact head on its structural feature junction block, is provided with stage clip between upper contact head and junction block; Described upper contact head and moving contact upper end clamping, the moving contact lower end is connected with automatic circuit one terminal electricity, and the automatic circuit another terminal is by connecting axle and lower contact is electric is connected; The control section of described automatic circuit makes upper contact head break away from automatic circuit according to overlapping the action of number of times control moving contact.
As a kind of preferred version, automatic circuit described in the utility model upper end is provided with falls the operation ring.
As another kind of preferred version, automatic circuit described in the utility model adopts vacuum arc extinguish chamber structure.
As another kind of preferred version, automatic circuit described in the utility model bottom is provided with the state display screen.
As another kind of preferred version, upper contact head described in the utility model and lower contact are silver-plated surface.
As another kind of preferred version, connecting axle described in the utility model is the cast copper silver plate.
Secondly, insulator described in the utility model adopts porcelain bottle insulators.
In addition, insulator described in the utility model is single insulator or double insulator.
The utility model beneficial effect.
The utility model upper contact head is connected with automatic circuit one terminal electricity by moving contact, the automatic circuit another terminal is connected with lower contact electricity by connecting axle, well solve the branch line transient fault by automatic circuit, need not to change fuse, avoid the situations such as circuit breaker trip, effectively improve power supply reliability.
The control section of the utility model automatic circuit makes upper contact head break away from automatic circuit according to overlapping the action of number of times control moving contact.Control upper contact head by moving contact and break away from automatic circuit, when the circuit permanent fault, the automatic circuit unsuccessful reclosing just falls automatically like this, visible obviously cut-off point; Non-maintaining; Have the advantages such as vacuum extinction, improved product quality.
Description of drawings
Below in conjunction with the drawings and specific embodiments, the utility model is described further.The utility model protection range not only is confined to the statement of following content.
Fig. 1 is the utility model structural representation.
