Technical Field
The utility model belongs to the technical field of the transformer distribution, more specifically say, relate to a high voltage power supply has a power failure incoming telegram alarm.
Background
At present, various kinds of power transformation and distribution stations are generally built in daily production work of various large-scale factories without power supply, the on duty of the power transformation and distribution stations is the daily operation of electrical operators, and the operators often have distance intervals between the on duty room and the power distribution room and field equipment, so that the operators cannot find and process the power distribution stations at the first time during power failure. Due to the above problems, when the high voltage power supply is powered off or powered on, the field device may be suddenly stopped or started, which brings a safety hazard to production, and the electrical operator may bring a greater loss to the plant due to an excessively long reaction time.
SUMMERY OF THE UTILITY MODEL
In order to solve the technical problem, the utility model provides a high voltage power supply has a power failure incoming telegram alarm, the purpose is placed high voltage power supply has a power failure incoming telegram alarm in electrical operation personnel on duty indoor, when high voltage power supply has a power failure or when coming the call suddenly, can in time remind the personnel on duty quick response, makes corresponding operation, will reduce because of the loss that has a power failure or come the power and cause.
The technical scheme of the utility model is that:
a high-voltage power supply power failure and power supply alarm comprises an intermediate relay, an alarm control box, a low-voltage power distribution loop and an alarm control box, wherein the intermediate relay is arranged on a voltage mutual inductance loop of a high-voltage PT cabinet; an input loop of the intermediate relay is connected in series with a voltage transformer in a voltage mutual inductance loop of the high-voltage PT cabinet; the low-voltage distribution box loop comprises a UPS (uninterrupted power supply), an intermediate relay output loop, a change-over switch and an acousto-optic alarm which are connected in series.
The high-voltage power distribution room is a place where high-voltage electrical operators work daily, the electrical operators cannot directly contact and measure due to unsafe factors of a high-voltage power supply, the high-voltage PT cabinet is often arranged in the power distribution room, a high-voltage transformer in the high-voltage PT cabinet is electrical equipment which transforms the high-voltage power supply into low voltage through electromagnetic induction, and the transformed low voltage provides reliable data for collecting power failure and power supply of the high-voltage power supply. Compared with the prior art, the scheme adds the intermediate relay KA in a voltage transformer loop in the high-voltage PT cabinet, and controls the power failure and power on alarm to send out audible and visual alarm by utilizing the normally closed and normally open auxiliary contacts of the intermediate relay KA; the low-voltage power distribution loop power supply of the alarm control box adopts a UPS (uninterrupted power supply), so that the stability of the equipment is realized.
Based on the above scheme, the utility model discloses following improvement has still been made:
furthermore, the alarm control box panel comprises an indicator light of the audible and visual alarm and a control end of the change-over switch, and a low-voltage distribution loop of the alarm control box is arranged in the alarm control box.
Further, the high-voltage PT cabinet voltage transformer loop also comprises a miniature circuit breaker connected in the loop in series.
The utility model has the advantages that: the high-voltage power supply power failure and power supply alarm is placed in an electrical operator duty room, when the high-voltage power supply suddenly fails or has power, the operator on duty can be reminded of quickly reacting to make corresponding operation, and loss caused by power failure or power supply is reduced; convenient use, single operation, low manufacturing cost, scientific design and easy popularization.

Detailed Description
As shown in fig. 1 and 2, the power failure and power supply alarm for the high-voltage power supply comprises an intermediate relay KA arranged in a voltage transformer loop of a high-voltage PT cabinet, a low-voltage power distribution loop of an alarm control box and the alarm control box; an input loop of the intermediate relay is connected in series with a voltage transformer in a voltage transformer loop of the high-voltage PT cabinet; the low-voltage distribution box loop comprises a UPS (uninterrupted power supply), an intermediate relay output loop, a change-over switch and an acousto-optic alarm which are connected in series. The high-voltage PT cabinet voltage transformer loop further comprises a miniature circuit breaker connected in the loop in series. The alarm control box panel comprises an indicator light of an audible and visual alarm and a control end of a change-over switch, and an alarm control box low-voltage distribution loop is arranged in the alarm control box.
The working principle of the circuit is that after the UPS of the 10KV high-voltage power supply is powered on, a power failure alarm loop is connected, an audible and visual alarm HR works, at the moment, the change-over switch SA is rotated to ②④ to be powered on and an alarm loop of the incoming call is powered off at the same time, and the audible and visual alarm HR stops working, when the high-voltage power supply is powered on, a high-voltage transformer TV in the high-voltage PT cabinet is powered on, so that the intermediate relay KA is powered on, the normally-open contact NO of the intermediate relay KA is closed, the normally-closed contact NC is disconnected, the power failure alarm loop is powered off, the power failure alarm loop is powered on, the audible and visual alarm loop is powered on, so that the audible and visual alarm HR works to alarm when the knob switch SA is rotated to ①③ to be powered on and the power failure alarm loop is powered off, so that the normally-open contact NO of the intermediate relay KA and NC are reset, the normally-closed alarm loop is powered off and the audible and visual alarm loop works to alarm HR when the power failure occurs.
