According to the end cover component structure, the overload protector is arranged in the end cover of the motor without additionally occupying the space of the breaker and equipping equipment to protect the motor, a self-recovery function is provided, the structure is simple, the cost is saved, and the safe reliability for motor running is enhanced.
Description
Technical field
The present invention relates to machine field, particularly relate to a kind of end-cap assembly structure of circuit breaker motor.
Background technology
In the drive unit of distribution apparatus circuit breaker; because breaker structure is complicated; parts are more; its drive motors often can transship due to uncertain factor; time one length will make burn-down of electric motor; circuit breaker cannot normally work, and even also can burn whole circuit breaker and transformer substation system thereof time serious, causes very large loss to user.
In order to solve the problem, part producer adds a fuse on the loop of outside motor input power, and when the load, fuse burns, thus can avoid burn-down of electric motor; But this kind of operator guards is generally used for and is installed on the stator winding of series machine, has certain limitation, and still there is some weak point following in this kind of operator guards:
1, fuse burns rear motor and can not normally start, and could start after must changing fuse;
2, fuse is arranged on outside motor, on the one hand, which occupies certain space, and on the other hand, user need be equipped with corresponding fuse;
3, fuse just can only fuse when input current is excessive, and when when ambient temperature is too high or machine operation temperature is too high, electric current is little, fuse can not action, can not protect motor well.
Summary of the invention
The object of the invention is to for the problems referred to above; a kind of end-cap assembly structure of circuit breaker motor is provided; overload protective device is serially connected on rotor winding; not only can be used for the reliably protecting of series machine; and can be used for the reliably protecting of direct current machine, have the advantages that structure is simple, safe and reliable.
The object of the invention is to be achieved through the following technical solutions:
A kind of end-cap assembly structure of circuit breaker motor, comprise end cap, described end cap central place has axis hole, the left and right sides that its inside is positioned at axis hole is symmetrically arranged with the first carbon brush component, second carbon brush component, described carbon brush component contacts with epitrochanterian commutator, the front and back bilateral symmetry being positioned at axis hole in described end cap is provided with the first holder, second holder, locating rack is provided with between described second holder and axis hole, it is overheated that the interior installation of described locating rack has, the overload protective device of excess current protective function, one end and first carbon brush component of described overload protective device are electrically connected, first electrode of its other end and power supply is electrically connected, second electrode and second carbon brush component of described power supply are electrically connected.
As a preferred embodiment of the present invention, in described end cap, be provided with reference column.
As a preferred embodiment of the present invention, described first holder, the second holder all have fixing hole.
As a preferred embodiment of the present invention, described locating rack is inverted L-shaped structure.
As a preferred embodiment of the present invention, described end cap between overload protective device and the second carbon brush component has wire casing, is convenient to cabling.
Beneficial effect of the present invention is; the end-cap assembly structure of described circuit breaker motor is by being installed on electric motor end cap inside by overload protective device; without the need to additionally taking the space of circuit breaker; do not need to be equipped with equipment in addition to go to protect motor yet; and have self-recovering function; structure is simple, provides cost savings, and enhances the security reliability of motor operation.
