Abstract
The invention relates to a heater operation monitoring device and belongs to the power system substation power equipment heating device field. The heater operation monitoring device is structured in the following manners that: a heater (1) is connected with a monitor (3) through a current transformer (2); the monitor (3) is provided with an indicating lamp D2 (4); and the indicating lamp D2 (4) is a light-emitting diode. According to the heater operation monitoring device, whether the heater is abnormal or not can be accurately judged through lamp light indication. The heater operation monitoring device of the invention is required to effectively solve practical problems in field work. The heater operation monitoring device can be sized to fit the practical spatial sizes of components such as a switch cabinet and a circuit breaker mechanism box; and the operating condition of the heater can be indicated through lamp light. The heater operation monitoring device has the advantages of small size, portable convenience, simple and reliable installation, and convenient check, and is suitable for installation of heaters in different models, and can assist in effectively improving the efficiency of the check and maintenance of a substation.
Description
one, technical field
The invention belongs to power system transformer substation power equipment heating arrangement, spy relates to a kind of supervision well heater running gear.
two, background technology
In recent years along with the fast development of electrical network, the speed that renewal of the equipment is regenerated is accelerated, the well heater that substation breakers mechanism case, switch cubicle etc. adopt still can only monitor heater power source situation, in tour maintenance process, usually produced problem is as follows: 1, because isolating switch well heater is arranged on higher position, personnel cannot see well heater, or need to lift ladder climbing, therefore very painstaking, and owing to using cat ladder to reduce safe distance, there is potential safety hazard; 2, switch cubicle internal heater cannot open door of switch cabinet due to security reason, cannot judge well heater whether normal heating; 3, disconnector heater counter is maked an inspection tour needs use five unlocking prevention key, and clear stipulaties arbitrarily must not use unlock key in safety regulations, violate safety regulations and there is larger potential safety hazard, for above-mentioned reasons, bring very big inconvenience to tour maintenance work, greatly reduce the efficiency of making an inspection tour and safeguarding; For this reason, spy of the present invention arranges a kind of supervision well heater running gear, puts forth effort to solve the problem that inconvenience maked an inspection tour by well heater.
three, summary of the invention
For solving the problem: this city invention spy provides a kind of and monitors well heater running gear: it is characterized in that: well heater (1) is by current transformer (2) link monitor (3), (3) are provided with pilot lamp D2(4 with monitor), described pilot lamp D2(4) be light emitting diode.The present invention runs, and current transformer senses that well heater runs the secondary current being, powers, monitor the diode by inside to monitor, after current/voltage is carried out dividing potential drop by electric capacity and resistance, makes the lamp of pilot lamp D2 luminous.And well heater is when when there being power supply, internal fault cannot heat, because not passing through electric current in well heater, now electric current is 0, therefore the lamp of pilot lamp D2 is not luminous, and well heater is normal at power supply, inner non-fault, there is the electric current passed through in well heater, form loop, then pass through electric current, make the lamp of pilot lamp D2 luminous, and now illustrate that well heater runs and home loop is connected normal.
Beneficial effect of the present invention: accurately can judge that whether well heater is normal by lamplight pointing, and it is light to realize compact, reaches and be convenient to install simply, make an inspection tour object easily.The supervision well heater running gear that the present invention makes requires the practical problems effectively solved in work on the spot, has specifically accomplished: 1, control heater running monitoring device conforms to the real space such as switch cubicle, circuit breaker mechanism case, has accomplished small volume and less weight; 2, can the running status of lamplight pointing well heater; 3, install simply, reliably; 4, the well heater being adapted to various different model is installed; Thus effectively improve the efficiency of substation inspection maintenance.
The present invention, in real work, can collect the size etc. of each switch cubicle, circuit breaker mechanism case, isolator operating mechanism case; According to the size collected, design circuit figure, can realize the function of heating arrangement operation monitoring; Weld according to circuit diagram; Carry out entirety debugging, finally will realize the function for monitoring to well heater running status, accurately can judge that whether well heater is normal by lamplight pointing, and it is light to realize compact, reaches and be convenient to install simply, make an inspection tour object easily.
