Description
Technical field
A kind of motor protecting device is the utility model is related to, belongs to radiation ventilator field, it is specifically a kind of
The spontaneous electric slip ring radiator of motor.
Background technology
Generally use stator variable-frequency control technique during oil-field flooding at present, and upgrade and have developed water injecting pump " one drag more "
Rotor frequency conversion speed-adjusting system, supporting winding motor use, and have " total head opens pump, total head and to pump electric current small ", " low-speed range
Greatly ", outstanding advantages of " no frequency modulation blind area ", but the fan-free cooling system of motor self power generation slip-ring device, production in summer are frequent
Generation slip ring and bakelite burn observations, influence the normal water filling in oil field.Slip ring is by conducting ring, brush with tail, brush carrier, conduction
The components such as bar, collector ring and slip ring cover form.The winding of phase-wound rotor is similar with stator winding, and three-phase windings are linked to be star,
The beginning for not having phase winding is connected on three slip rings made of copper, and slip ring is fixed in shaft.Ring and ring, ring and shaft are all mutual
Insulation, the carbonaceous brush that press against by one group of spring is connected with external circuit.
Under normal operating conditions, the temperature of carbon brush is generally in 50 DEG C -80 DEG C (40 DEG C or so of temperature rises), every piece of carbon brush work
Electric current is in 20A-100A.Brush spring pressure ratio is more uniform, and carbon brush activity is freely and bite phenomenon without friction.Carbon brush is transported with slip ring
The heat produced in row is taken away by ventilating system.I.e. fever reaches in a basic balance with heat dissipation.But it is higher to work as summer temperature, water injecting pump
Room ventilation is not smooth, causes motor self power generation slip-ring device bulk temperature excessive (52 DEG C average)；Employee every 2 on duty is touring when small
Motor temperature is tested during inspection, it is impossible to motor temperature rise is found in time, if requiring employee on duty to be examined per half an hour
Testing temperature, then the increase of employee work amount, working procedure are cumbersome；Device heat dissipation system existing defects, lead to by spontaneous electric slip ring shield
Air holes progress heat dissipation effect is bad, causes self power generation slip-ring device to be easy to cause motor insulating layer aging when exceeding rated temperature,
Water filling pump motor self power generation slip ring insulator bakelite skin deformation, effectively causes motor self-generating device slip ring and bakelite
Burn, clamp spring and carbon brush failure；Since carbon brush shortens, contact resistance and additional resistance becomes larger, brush spring pressure diminishes, if work
Make electric current increase, the balanced capacity of system reduces during temperature change, and part carbon brush temperature will raise, so that whole system temperature liter
It is high.
Traditional slip ring ventilating system is often since cooling air quantity is inadequate, and the closed air passage of slip ring has blocking or leaks out
Cause carbon brush and collector ring heating, the safe operation of serious threat generator.Therefore, the monitoring to collector ring and carbon brush, safeguard simultaneously
The failure of its generation of timely processing and damage, are to ensure one of important process that generator is run steadily in the long term, avoid fever from closing
Key still puts prevention first, and effectively solves the problems such as collector ring heating is burnt out, and ensures motor safety reliability service, improves coiling electric motor production
The economic benefit and social benefit of product.
