Since the relay relay coil KO is powered, the normally-opened contact KO is closed and the normally closed contact KOI is turned off. Because the impedance of the green signal lamp LD is much smaller than that of the anti-kick relay coil KO, Anti-trip relay contact KO: The anti-trip relay coil KO is kept in a power receiving state. Due to the relay relay contact KO, disconnecting the closing circuit, no matter whether it is an accident or artificial opening, manual closing cannot be achieved. Similarly, when using the jump relay TWI in the comprehensive protector to replace the green signal, due to the jump position The resistance value of the relay coil of the relay relay TWI and the ZN 63 A vacuum circuit breaker in the anti-kick relay KO is unreasonable, and the electromagnetic interference is serious, so that the comprehensive protector emits continuous and different sound. Improvement of the original design control loop According to the analysis of Figure 1, the vacuum circuit breaker wiring is unreasonable. Although the design idea is to directly monitor the state of the closing coil by the green signal lamp or the jumper relay TWI. The anti-trip relay coil KO is either held by the green signal lamp LD or the mutual electromagnetic interference of the jump relay TWI coil, so that normal loop control cannot be realized. The green signal lamp LD or jumper relay coil is separately led to a breaker normally closed auxiliary contact DL 4 in series. After the improvement, it can solve the problem and monitor the status of the breakers. The use of a comprehensive protector integrated protector is an automatic protection component that integrates multiple functions such as protection, measurement, fault recording, and communication, and its superior performance is unmatched by conventional relay protection. At present, it has been widely used in power supply systems and has the tendency to replace conventional relay protection. Many integrated protectors are equipped with an anti-trip relay TB J, which should make better use of the anti-trip relay TBJ on the integrated protector; at the same time, the jumper relay TWJ coil on the integrated protector does not have to bring out a circuit breaker normally closed auxiliary. Contact, can directly monitor the circuit breaker closing coil HQ, but must disconnect z N 63 A 0, improve the vacuum circuit breaker secondary circuit closing control diagram vacuum switch on the jumper circuit breaker KO coil connection. Chromium(III) sulfate usually refers to the inorganic compounds with the formula Cr2(SO4)3.x(H2O), where x can range from 0 to 18. Additionally, ill-defined but commercially important "basic chromium sulfates" are known. These salts are usually either violet or green solids that are soluble in water. It is commonly used in tanning leather. Basic Chrome Sulphate,Basic Chrome Sulfate for Tannery,Tanning Agent Basic Chrome Sulfate HENAN JINHE INDUSTRY CO.,LTD , https://www.speciatyelement.com
Since 33% of the anion charges are due to hydroxy ions the basicity is 33% (but in tanning jargon it is known as 33% reduced). Products with higher basicities, e.g. 42% or 50% may be obtained by the addition of sodium carbonate, these are often used in combination with Sodium Formate. The sodium sulfate is often left in the technical product since it is inert with respect to the tanning process. It is important to fully reduce the hexavalent chromium to trivalent since the hexavalent is more likely to cause health problems for tanners and leather consumers.
